What are UK companies doing to save global coastlines?

By Magda Nawrocka-Weekes, CCell

The reality of climate change can no long be ignored. Despite scientific research and the warnings given half-hearted initiatives mean that the world is in a perilous state. The past five years have been the hottest since records began. We’ve seen the increased frequency of extreme weather events and the visible effects of dumping tonnes of plastic into our environment. Because of this it is clear that we now need to act.

To help combat these changes, governments around the world have made a string of commitments to reduce carbon output, increase recycling and to find alternatives to single-use plastics. These commitments, however, are rarely kept. 

As 16-year-old Swedish climate change activist Greta Thunberg said: “Adults keep saying, we owe it to the young people to give them hope. But I don’t want your hope, I don’t want you to be hopeful, I want you to panic.”

Amongst this panic, anxiety and fear, there is cause for hope. Success stories are abundant if you know where to look: Campaign groups have effectively lobbied for legislation, already reducing single-use plastics, new technologies are making energy cleaner and companies are using their resources to help protect our coastlines.

With that in mind, here’s how UK companies are saving global coastlines and sea life… 

Halting Coastal Erosion

A big issue, that often goes unreported, is the damaging effects of coastal erosion. Not only does it threaten communities who live and work on the coast, but it also affects the marine life that relies on these ecosystems.

Rising sea levels and increasingly severe weather events, such as Hurricane Dorian, threaten to submerge millions of kilometres of coastline around the world. There are island communities that may be lost forever within the next 30 years, and the UK will not fare well against these changing conditions.

Fortunately, there are quick, simple and cheap solutions. For example, Huesker’s SoilTain coastal protection tubes. These are long tubes, made from a semi-permeable fabric, that are positioned along the coast and filled with a sand-water slurry mix. The water drains back into the sea, leaving only the sand behind. Acting like a wall of sandbags, a common flood preparation, these tubes provide immediate but short-term protection from erosion by waves. They can also be placed further from the shore where they act as a breakwater to incoming waves and storms. Here some marine flora and fauna can begin to grow on the tube structures, allowing them to achieve balance with the environment they are introduced to. 

Another UK company working to protect global coastlines is CCell. They grow artificial reefs over a number of years, on which corals can proliferate. By passing a safe, low-voltage current through the seawater, minerals (mostly calcium carbonate) are drawn in and create a “natural concrete” around a steel structure, while helping coral to grow 2-3x times faster. In nature, coral reefs protect vast swathes of coastline and provide a habitat for 25% of marine life. CCell’s approach uses renewable wave energy for power, with a focus on boosting the local economy around beachfront businesses through eco-tourism, coral restoration, and local manufacturing. All of this while providing near-nature coastal protection.

Getting Hotels Involved

Beachfront businesses are acutely aware of the risk of coastal damage and pollution. Not only does pollution put people off visiting their beach but coastal erosion may literally cut the ground from under their feet.

Fortunately, some hotels and other businesses are taking action. The Watergate Bay Hotel in Cornwall, one area most reliant on coastal tourism, has made some dramatic changes to its operations. They now use 100% renewable energy and filter their pool water with UV to minimise chlorine use and also organise beach clean-ups to remove plastic and other pollution from the beach.

Minimising the plastic that ends up polluting our oceans can be achieved by reducing the amount of plastic produced in the first place. This is the reasoning behind the monumental decision made by the Marriott and Intercontinental Hotel chains to reduce their use of single-use plastic bottles for their toiletry products. By switching to bulk dispensers, they have already prevented 170 tonnes of plastic from going to landfill and eventually ending up in our oceans.  

Recycling Ocean Plastic

As well as coastal erosion and sea levels rising, the other indisputable issue affecting marine life is plastic. From the more apparent giant garbage patches in the Pacific Ocean to the discovery of microplastics, this form of pollution is everywhere we look.

Microplastics are caused by the degradation of plastic materials into smaller pieces. Small plastic fibres break off from things like fleece jackets and fishing nets, and are also found in the form of micro-beads that were added to cosmetics, such as exfoliators. These microplastics are particularly harmful to marine life as they are easily swallowed and can accumulate to toxic levels.

A number of charities have been set up to help remove some of this plastic from our oceans, with clean-up teams and autonomous technology having some impact. A number of UK companies are also helping to remove plastic by making it financially beneficial.

For example, Finisterre uses plastic recovered from the ocean and elsewhere to make their swimwear, using proceeds to support the charity Surfers Against Sewage, and raising awareness of microplastics through their fashion range. Another UK company, GANT, use only recycled ocean plastic in their clothing. Both provide a financial incentive to support ocean clean-up, help raise awareness, and allow customers to make ethical purchasing decisions.

Supporting charities/pressure groups

It is becoming increasingly easy, as a customer, to make environmentally conscious decisions. The improved availability of ocean-friendly options is due in part to consumers voting with their wallets, funding products and initiatives they genuinely believe in. However, on the other side of the coin, existing businesses are wondering what they can do to help. After all, if you don’t use plastics and aren’t based near the coast, these examples will be tough to follow.

However, there are other ways to support environmental protection and raise awareness. Ecotricity not only delivers renewable energy and gas to their customers, but they have also partnered with Sea Shepherd, the largest marine protection charity in the world. When a customer switches to Ecotricity, the company donates up to £60 to Sea Shepherd to help protect marine life and clean up plastic from the ocean.

Business owners looking to take action should start by considering the marine protection charities or pressure groups they could support. Ideally, ones that share their values and ethos, as well as ones that makes a demonstrable difference.

On a business-wide scale, there are other ways to make an impact. Looking into how you can reduce, reuse and recycle is an excellent way to start. Is it possible to cut back on energy use and/or switch to a renewable supplier? Can the reuse of materials be encouraged, such as offering customers discounts when they return packaging? Perhaps investigate sourcing recycled ocean plastic for some products?

At times it can feel like our choices don’t have a tangible effect on the climate crisis, and its associated problems, from coastal erosion to plastic pollution. But we need to start thinking differently.  Whether we are consumers, business owner or leaders in other type of organisation we have purchasing power and can use it to demand environmental protection. Together we can create a network that will make a huge difference
