Climate Action Week Round-up

The last week has been full of exciting activities as a part of Climate Action Week in the run-up to COP26, the 26th UN Climate Change Conference of the Parties. The Sustainability Team have hosted a number of events at the University and it was fantastic to see so many people getting involved and voicing their opinions.

The week began with an online session hosted by Sustainability Coordinator Emily Mason, called ‘SDG and a Cup of Tea: Climate Action – a COP26 Discussion’, where staff came together to discuss the UN Sustainable Development Goals (SDGs). There was a particular focus on Goal 13, Climate Action, and we discussed the ways that staff can directly support rapid carbon reduction at the University and beyond. Together, we discussed key sustainability topics and came up with lots of new exciting suggestions and ideas.

On Tuesday, we celebrated the launch of the University of Kent’s Sustainability Strategy. The online launch was introduced by Professor Richard Reece, Deputy Vice-Chancellor Education and Student Experience, and then Dr Catherine Morris, Environmental Adviser, presented the main four themes that run through the strategy. This was followed by a panel discussion on the future of Sustainability at Kent, chaired by Dr Anthony Manning, Dean for Internationalisation, allowing us to discuss how the strategy will be implemented across the University. This provided the opportunity to share different views and opinions, and to discuss a variety of important topics. We are looking forward to continuing these important conversations, so please contact the Sustainability Team at: sustainability@kent.ac.uk if you want to talk further.

Dr William Rowlandson, Senior Lecturer in Hispanic Studies, took us on a Sustainability Tour following the SDG trail around the Canterbury campus on Wednesday. The sun was shining as we walked around our beautiful campus, discussing topics such as sustainable innovation, campus biodiversity, and responsible consumption. Our tour ended with an introduction to the Kent Community Oasis Garden (Kent COG) from Emily Mason where we talked about SDG 17 – Partnerships for the Goals, learnt about the work that volunteers are doing in the garden, and signed up to become volunteers ourselves!

Sustainability Tour

COP26@Kent: Co-create your campus of the future, held at the Gulbenkian yesterday, brought the many different areas of sustainability together allowing us the opportunity to talk about the challenges and successes of sustainability at Kent. The areas that were represented included: Waste and Procurement, Energy and Buildings, Curriculum and Research, Sustainable Food, Biodiversity and Grounds, Transport (including representatives from Stagecoach and Bird), and Student Action (including representatives from the SAC Sustainability Working Group, and the ECS Society). The Sustainability Ideas Factory was also launched, giving students the chance to win up to £500 by submitting their best ideas about how we can make the University of Kent more sustainable. We received lots of input from staff, students, and the public at the Gulbenkian on Thursday and we are looking forward to implementing your ideas and working together to make change across the different areas of sustainability within the University.

We want to thank everyone that took part in Climate Action Week this year, and also those that made holding these exciting events possible. With the new Sustainability Strategy published, we are looking forward to connecting and collaborating with others to make the Sustainable University of the Future that we aspire to create a reality.

Celebrating Black Environmentalists #BlackHistoryMonth

Sustainability has always been based off of equity. Equity for the planet and people. Without social equality and justice we cannot have environmental sustainability.

The sustainability/environmental movement must be more vocal against systemic racial violence, injustice and inequalities, committing to listen, learn and take action. It is also a time to reflect on issues within the sustainability community.

We know that those most affected by climate change are the poorest and tend to be from the Global South and black and minority ethnic communities, so why does the environmentalist movement lack diversity?

These conversations can be uncomfortable, but we should feel uncomfortable about the current situation. As people who care about the world we live in, we should be actively engaging with this issues and seeking to dismantle the systems that have led to such injustice and inequality for our fellow humans and the environment we rely on.

To mark Black History Month we wanted to share the voices of black environmentalists and celebrate their work. In all the work we do we will continue to seek out more representative voices and sources to provide a fuller picture of delivering sustainability globally.

“America is segregated and so is pollution. Race and class still matter and map closely with pollution, unequal protection, and vulnerability.  Today, zip code is still the most potent predictor of an individual’s health and well-being.  Individuals who physically live on the “wrong side of the tracks” are subjected to elevated environmental health threats and more than their fair share of preventable diseases. Still, too many people and communities have the “wrong complexion for protection.” Reducing environmental, health, economic and racial disparities is a major priority of the Environmental Justice Movement.”

The Sustainability Team welcomes new member, Bella.

Hi everyone! My name is Bella, and I am an Environmental Social Science student at the University of Kent. I have recently joined the University Sustainability Team to carry out a work placement as part of my undergraduate degree, and I am very excited to get involved with the amazing work that the Sustainability Team are doing. I really wanted to do a year in professional practice to get experience of working in a professional environment, to learn more about my own interests and potential career paths, and to put the skills that I have learnt throughout my degree so far into practice.  

My main interests are community conservation and learning about how we can act to mitigate the climate and ecological crisis. I am looking forward to working on a variety of projects with the Sustainability team that I hope will help to improve biodiversity and bring our local community together to make positive change. This term I will mostly be working on the Hedgehog Friendly Campus project and with the Kent Community Oasis Garden (KentCOG), where volunteers can come to spend time in nature, garden, and grow food.  

The Hedgehog Friendly Campus project is particularly exciting for me as I have been lucky enough to have regular hedgehog visitors in our garden at home during the lockdown, and so I am passionate about raising awareness of the dangers that hedgehogs are currently facing. In the past decade we have lost over a half of rural hedgehogs and a third from towns and cities, largely due to habitat loss and fragmentation. This forces hedgehogs to move into more urban areas where they may not be able to find enough food and water and are threatened by poison or traffic. The University of Kent has already been awarded the Silver Hedgehog Friendly Campus status as a result of efforts to make the campus a safer place for hedgehogs to live, and this year we will be working towards achieving the Gold Hedgehog Friendly Campus status! 

I also enjoy learning about the impact that the climate crisis is having on our mental health and, with the Wellbeing subgroup from the SAC Sustainability Working Group, set up a series of Climate Cafés to create a space where we can safely express our feelings about climate change. We are hoping to run more of these online events so please get in touch if you are interested. In my free time, I enjoy travelling, spending time in nature (especially at the beach with my dog), meeting up with my friends and family, and watching Marvel movies whilst I crochet!  

If you have any questions about the projects that I will be helping with, or want to get involved, please feel free to contact me via email: is348@kent.ac.uk 

What’s happening with the Hedgehogs?

Guest article from School of Anthropology and Conservation student Katie Hargrave-Smith


What’s happening with the Hedgehogs?

The hedgehog, or the Western European Hedgehog (Erinaceus europaeus) to be specific, is a national treasure for us in Britain. We have few wild charismatic mammals as we hunted many to extinction, or caused mass habitat loss. The hedgehog is Britain’s only spiny mammal, and once upon a time people were almost guaranteed to see a hedgehog in their garden in summer. Unfortunately, the hedgehog population has declined by up to 50% since 2000, and are now vulnerable to extinction.

This is largely due to human action. As we continue to change how we use land , we encroach on hedgehog habitat, and by walling our gardens have removed vital remaining habitat from them. They also create nests at ground level, so are vulnerable to grounds management. Furthermore, the defence mechanism of hedgehogs is to curl up into a ball, as their spines fend off predators trying to eat them. However, this defence mechanism is not so effective against humans, as cars often don’t think to drive slowly on roads where hedgehogs could be, or to check bonfires where the hogs might be nesting. And finally, there is not enough consideration given to hedgehogs when people decide to put out slug repellent or rat killer, and hedgehogs are often the unfortunate victim.

 

What can you do to help?

There are a number of things that everyone can do to help hedgehogs; some simply take seconds, while others require a small amount of effort (but it’s worth it to help protect this wonderful creature!) We have used ideas from both the British Hedgehog Preservation society and Hedgehog Street. Here are 10 things you can do, in order of ease:

1)      The Big Hedgehog Map

If you ever see a hedgehog, even if it has sadly died, it is incredibly important, and easy, to log it to the Big Hedgehog Map. This allows conservationists to follow hedgehog populations. It also helps highlight areas for action, such as on a road where hedgehogs are often being killed, a sign can be put up to warn people to drive carefully at night and be aware of hedgehogs. The map also allows you to backlog sightings, so if you saw a hedgehog a year ago and remember where, you can log it!

2)      Don’t litter

Although this one goes without saying, sometimes it is important to say it. Hedgehogs can easily get caught in litter and can also use it in their nests thinking its foliage. Why not make a point to pick up litter when you go out, and tell your friends/family why? Spreading awareness is always helpful.

3)      Check before you mow or strim

Always make a point to check for hedgehogs before you mow the lawn or do any strimming. If it’s not you who does these activities, make sure to mention it if you know someone else is about to.

4)      Make sure bonfires are hog-safe

Hedgehogs see logs stacked up and think of it as an ideal nesting spot, unaware of the danger of bonfires. As hedgehogs curl up when threatened, they sadly do not escape the flames. If you or someone you know is building a bonfire, make sure they know to either build it the day of the bonfire, or to move it the day of, as hedgehogs find nests at night. If you know that a public bonfire night is being organised (such as the annual Bonfire Night), why not contact the organisers to make sure they are being hedgehog safe?

5)      Stop using chemicals

Worms, beetles and other invertebrates make a tasty meal for hedgehogs, and repellents, insecticides and pesticides are all toxic for hedgehogs. These chemicals shouldn’t be necessary in a well-managed garden, but if you feel you have to use them, why not search for a hog-safe repellent? Such alternatives could include using coffee grounds, wool pellets, or slug tape (and there are more!)

6)      Put out food and water

Why not put out some food and water for hedgehogs to enjoy? They eat hedgehog food (the brands Spikes and Brambles are the only Hedgehog Friendly Campus approved brands), and meaty cat and dog food. Putting out a water dish is especially important for hedgehogs during dry spells. However, please don’t put out your pumpkin this halloween, it’s bad for hedgehogs!

7)      Call for help if you see a hedgehog during the day

Hedgehogs are nocturnal, so if you see one during the day it is probably unwell. If it seems like it is going somewhere with intention, or it is carrying leaves in it’s mouth for its nest, it could be okay, but if unsure call a local rescue service for advice.

8)      Create a wild corner

If you have a garden, why not allow a corner to grow naturally? They love brambles, hawthorn, wildflowers,  and nettles! This will create a great habitat for hedgehogs, from nesting areas and foliage, as well as lots of prey for them to eat! You can add branches to create structure.

9)      Make your pond hedgehog safe

Hedgehogs can swim! However, they cannot climb out of steep verges, so unless your pond has a bank, why not add a ramp to allow hedgehogs to climb out so that they don’t drown? You can add a ramp using wood, rocks or chicken mesh. Also, make sure that the water levels stay topped up.

10) Link up your garden

Making sure there is a hedgehog sized hole in your fence allows the hedgehog to roam between gardens. A 13x13cm (5×5”) hole will allow a hedgehog through, but not most pets. Make sure you speak to your neighbours if you share the fence and use this as an opportunity to share what you know about hedgehogs! You might inspire them to make other holes in their fences and make their garden more hedgehog friendly.

 

What we are doing to make our campus hedgehog friendly

The University of Kent became part of the Hedgehog Friendly Campus scheme in 2019, and members of the university recently undertook a survey to find out if there are hedgehogs present on campus. Ten tunnels were strategically placed around campus in which any small animals could walk through, over a strip of non-toxic ink and leave footprints on the other side.

As well as this, the university carries out regular litter picks around campus, including the woods on the site, and the Landscape and Grounds management team have had sessions to educate them on what to do if they find an injured hedgehog, how to check for them if they are about to strim and what risks there may be on campus for resident hedgehogs. Thanks to these efforts, the University of Kent has been awarded the Bronze award by the Hedgehog Friendly Campus Scheme and is looking to work towards the silver award.

A guide to student-friendly toiletries plastic reduction: blog post #4

Guest post by SDG Ambassador Julia Daly

———————————————————————–

Welcome to the last blog post of this plastic reduction series. I’ve seen many undergrads already receiving their final results, and many postgrads, myself included, will soon be handing in (or have already handed in) our final dissertations. With this closure to the academic year, I will also be bringing this blog series to an end. But before I go, I would like to share two shampoo bar products that I have tried and loved. Shampoo bars that work for your particular hair type are, in my experience, the most difficult to find when it comes to plastic free alternatives, so I am THRILLED to have found two that both work.

Today’s focus are shampoo bars from two brands: Eco Warrior and Faith in Nature. Both are available from Holland and Barrett and Boots so very accessible. Eco Warrior are a British brand that make soap which is vegan, cruelty free and eco-friendly using recyclable packaging. Similarly, Faith in Nature are also UK based, cruelty free, vegan and reducing plastic use by using recyclable and recycled packaging. Eco Warrior are a purely soap bar company, whereas Faith in Nature provide a plethora of options: soap bars, liquid shampoo in fully recycled plastic bottles, the option of buying 5 litre or 20 litre bottles of liquid product to reduce plastic consumption and refill stations in stores across the country.

Eco Warrior – Shampoo Bar, Orange and Ginger Essential Oils, 100g for £4.00

A good size shampoo bar that lathered well when wet. As I’ve not had a great experience with shampoo bars in the past, I found that this one was the first to lather well and could be used by directly placing the bar onto my hair without leaving clumps of product behind. It does take a while to cover your entire head and get to the roots, I would say about twice as long as with liquid product. My hair didn’t need a lot of time to get used to the new product, perhaps a week or so, and after washing, my hair felt very clean and oil free. The only thing that wasn’t ideal about the product was that it seemed to half in size after every use, meaning that it only lasted about a month and a half. My hair, being thick and long probably expedited the use of the product so someone with thinner, shorter hair would definitely get a lot more use out of one bar.

Faith in Nature – Shampoo Bar, Coconut & Shea Butter, 85g on sale for £4.34, RRP £5.79

I have only just started using this shampoo bar but needed to include it in this post despite not giving it a full trial. Despite being a smaller bar, it doesn’t seem to use as much product per wash compared to the Eco Warrior bar implying it will last longer (picture shows new, unused bar on the left vs bar used for two washes on the right).

The thing I noticed which was consistent between bars is the necessary for patience to get enough product for a good lather. But once this is achieved, the result is squeaky clean. Both products weren’t particularly drying or moisturising, so you just achieve a neutral clean. Both bars had a pleasant, mild scent which does not linger in your hair once it is rinsed and dried which some people prefer. If you do like to have some scent to your hair or require extra moisturiser, I recommend following up with a conditioner but this is by no means necessary!

Shampoo is a product I personally use a lot of due to my hair length and type so it is great to find plastic free alternatives although they are not 100% perfect! These were definitely a step in the right direction and may work better for you than they do for me depending on your hair type.

Thus concludes my student friendly guide to plastic reduction series! I am so grateful for the opportunity to contribute to the Sustainability Kent blog as a Sustainability Development Goals Ambassador. Although I will no longer be a student in the very near future, I hope to continue sharing my personal plastic reduction journey perhaps through a newly created blog dedicated to plastic reduction. Thank you to everyone who has given me such wonderful feedback and I hope the series is helpful to students and non-students alike!

Maximising our green space at Medway

The Medway campus has a patch of green space that is underused and not particularly relaxing to spend time in (it is next to a busy road). However, the Medway sustainability group
made up predominantly of champions from Student Services know it has great potential to be developed into a space that could provide an alternative to an otherwise urban environment.

We aim to maximise the limited green space at the Medway campus by creating a quiet space for reflection that can be utilised by students, staff and the wellbeing team. As a group we have come up with a series of ideas and designs that utilise the campus’ small patch of woodland as a focal point for a wellbeing and art trail, incorporating music and natural sounds to break up the noise from the road. This will provide a unique space for alternative outdoor therapy for students accessing the University’s mental health services, and a space for all campus users to get away from it all.


We are now at the stage where we want to turn our ideas into a reality and are looking for students and staff to join our group to help us create a space that we can all benefit from.
We are looking for people who will bring new ideas into the group, are resourceful and are happy to volunteer their time on the site. At the moment we are on a break due to the Covid 19 pandemic, however if you would like to join the Medway Sustainability Group please email sustainability@kent.ac.uk and we will add you to our mailing list.

Printing the world to rights: how print firms are approaching sustainability in Kent and the UK

This is a guest blog from James Hale, a graduate of the University of Kent. Having studied English and American Literature, James now works as a freelance writer, penning his thoughts on anything and everything of interest. He’s passionate about sustainability, and loves helping to spread the word about how we can all factor it into our day to day lives.

————————————————————————————————————————–

Print is everywhere; it is so ubiquitous that we rarely notice it. When we think about printing, we tend to imagine newspapers, books, magazines, leaflets and cards, but how often do we stop to consider the impact large format print has on the environment?

Large format printing – the process by which the enormous billboards and banners of our modern world are realised – is everywhere, a major industry that populates our bus stops, shopping centres, train stations and more with vast advertising images.

We live in an ever-more eco-conscious world, and while we may rarely think about this type of printing or the impact it might have, print companies are working to make sure they can deliver their products in a way that is kinder to the environment around us.

Getting interested

For printing companies, however, finding ingenious ways to offer ecologically sensitive products is only half of the story. The Image Reports Widthwise Report published in June this year reveals that seven out of ten British print service firms have never once been asked by their clients about their eco-friendly credentials, despite the fact that a recent global census conducted by Fespa reported that 76% of printing companies worldwide said that their customers were keenly interested in environmental issues.

What’s especially notable is that these businesses felt it prudent to plan their strategies with that environmental interest in mind. Whether the UK is really lagging behind the rest of the world in its awareness of the ecological impact of large format printing, or whether this might be just a statistical anomaly, the point remains that there is a fundamental problem still facing the industry: how should they sell a service to clients who aren’t asking for it?

Communication, communication, communication

It’s an issue that some businesses have put a great deal of thought into. The Verdigris Project is an industry campaign that aims to raise awareness of environmental concerns and initiatives in the printing trade, and is sponsored by a number of industry giants, including HP, Kodak, Agfa and Fespa (a global collection of national associations for professional printers). It’s also hoped that printing companies will seek their own ways to inform clients about the environmental impact of their projects, and to confidently offer them greener alternatives.

Substrate procurement

The UK reportedly uses 12.5 million tonnes of paper every single year, and any environmentally-minded printing firm should be concerned about using recycled and sustainable paper wherever possible, and this means they need robust procedures for obtaining recycled paper.

Modern recycling techniques mean that large format paper made from recovered fibre can be just as good a printing substrate as ‘virgin pulp’. As a result some companies have opted to commit to procurement policies that insist on recycling-based solutions.

Other substrates

Of course, when we get into the realm of specifically large format printing, the substrate in question may not be paper-based at all. Many large banners and signs are printed on vinyl and other plastics, not to mention the many other materials of varying environmental friendliness.

If a large format printing firm wants to lessen the potential negative impact of their work on the environment, finding alternative substrates that don’t involve plastic would be an excellent place to start; much has been said lately about the growing unpopularity of plastic following David Attenborough’s BBC show Blue Planet II and the discovery of a plastic bag 35,000 feet down inside the Mariana Trench, the deepest known part of the world’s oceans.

Some firms, such as Kent-based industry leader PressOn, have adopted new and innovative print solutions to alleviate the problem. PressOn were an early adopter of products known as Tension Fabric Systems, which involve a printed sheet of fabric suspended across an aluminium frame, creating a large printed piece that is ideal for interior environments such as offices, malls and shops.

The metal frames are endlessly reusable for other printed designs, and the fabric that serves as the substrate completely removes the need for plastic. Nigel Webster, PressOn’s managing director, explains:

“Although popular in the States for a few years, we first started using tension fabric frame systems in the UK two years ago for one of our largest US based retail clients. PressOn always strive to promote this more environmentally friendly system to our clients, and it’s reassuring to see that the demand for this type of system has grown dramatically.

Brands in the retail sector traditionally use a lot of self-adhesive vinyl on their graphics inside the store and the shop windows, with regularly changing campaigns and offers to promote. By switching to the fabric frame system and installing aluminium frames in stores, we can print graphics directly onto more sustainable polyester fabrics using latex inks. These systems mean we don’t need to print, install and then remove and dispose of vinyl graphics.

The demand for eco-friendly print solutions has now extended to other sectors, too. They’re popular in corporate branded office environments (we’ve recently completed a project for Sky to use these systems in their offices), hotels, restaurants, bars and even to event and exhibition graphics too. Along with tension systems, other options for non-pvc products include paper wallcoverings from sustainable sources and also self-adhesive polyester fabrics as well. It’s great news for the environment and the print industry.”

Choosing the right inks

It could be said that the use of plastic and the wastefulness of large quantities of paper are more obvious problems than the ink used to create the printed designs — particularly as some varieties, such as petroleum and solvent-based inks, can be a source of gases that are harmful to the environment. Fortunately, there are several more ecologically friendly alternatives.

Eco-inks – made from vegetable oils or soya beans from sustainable farming environments – are becoming more widely available, while some printers are turning to UV-curable (UVC) inks. The liquid in UVC inks is aqueous-based; after printing, the ink is dried (or ‘cured’) via exposure to strong ultraviolet light. Significantly, however, these types of ink aren’t typically used by the large format industry, and are usually preferred by businesses producing packaging.

When it comes to large format printing, the best option usually lies in latex-based inks, which also don’t emit any unpleasant chemicals or odours, and have the added advantage of drying almost instantaneously after printing.

The environmental issues with some inks don’t end there, however. In order for paper and cardboard to be properly recycled into a clean pulp that can be reused as new paper, it must first be subjected to a process of de-inking to remove anything that may have been printed on it previously. Water-based, hydrophilic inks can be resistant to the alkaline floatation de-inking technique widely used in Europe; this is designed to separate ink from fibre and cause it to float to the surface, where it can be completely removed from the pulp.

Paper recycling is also an enormous endeavour – around 90% of Europe’s newspapers are printed on recycled paper – so finding inks that can be removed easily and efficiently is of paramount importance for eco-conscious printers.

In the end, the large format printing industry’s ability to be environmentally conscious rests as much with its customers as its service providers. The technology is there to print and recycle in a way that minimises chemicals and waste products; it only remains for those who commission billboards and large signage to be open to new techniques and approaches.
