Resource efficiency

Resource Efficiency

Energy, water and waste can often be big costs to manufacturing businesses and food waste has an understandably high profile with many groups. Single-use plastics have come under the spotlight since the BBC’s Blue Planet II brought the issue of ocean plastics to a wider audience and other issues are not far behind.

The circular economy is a new(-ish) term for an old idea, treating ‘waste’ as a resource, but the concept is as valid as it has ever been. Taken together with general resource efficiency, ‘circular’ thinking can save money and open up new opportunities. With many larger organisations adopting standards such as ISO14001 (environmental management) and ISO50001 (energy management) there can be additional benefits from aligning to your customers’ priorities. A good environmental record is also a proven means of attracting and retaining talent.

Green Knight can help you work through your resource consumption, identify opportunities to make savings, contextualise these more broadly and communicate them to your key stakeholders.

Planting tiny urban forests can boost biodiversity and fight climate change

Planting tiny urban forests can boost biodiversity and fight climate change Alex Thornton Fri, 08/07/2020 - 00:30 How much space do you think you need to grow a forest? If your answer is bigger than a couple of tennis courts, think again. Miniature forests are springing up on patches of land in urban areas around the world, often planted by local community groups using a method inspired by Japanese temples. The idea is simple — take brownfield sites, plant them densely with a wide variety of native seedlings and let them grow with minimal intervention. The result, according to the method’s proponents, is complex ecosystems perfectly suited to local conditions that improve biodiversity, grow quickly and absorb more carbon dioxide. The Miyawaki method The method is based on the work of Japanese botanist Akira Miyawaki. He found that protected areas around temples, shrines and cemeteries in Japan contained a huge variety of native vegetation that co-existed to produce resilient and diverse ecosystems. This contrasted with the conifer forests — non-indigenous trees grown for timber — that dominated the landscape. Miyawaki forests can grow into mature ecosystems in just 20 years — astonishingly fast when compared to the 200 years it can take a forest to regenerate on its own. His work developed into the Miyawaki method — an approach that prioritizes the natural development of forests using native species. Miyawaki forests can grow into mature ecosystems in just 20 years — astonishingly fast when compared to the 200 years it can take a forest to regenerate on its own. They act as oases for biodiversity, supporting up to 20 times as many species as non-native, managed forests. Local pollinators such as butterflies and bees, beetles, snails and amphibians are among the animals that thrive with a greater diversity of food and shelter. Greening urban spaces worldwide The popularity of Miyawaki forests is growing, with initiatives in India, the Amazon and Europe. Projects such as Urban Forests in Belgium and France, and Tiny Forest in the Netherlands, are bringing together volunteers to transform small patches of wasteland. Urban forests bring many benefits to communities beyond their impact on biodiversity. Green spaces can help to improve people’s mental health, reduce the harmful effects of air pollution, and even counter the phenomenon of heat islands in cities, where expanses of concrete and asphalt raise temperatures unnaturally high. Carbon sinks The potential for helping to combat climate change makes Miyawaki forests a particularly attractive option for many environmentalists. Reforestation is a key part of strategies to limit the rise in global temperatures to 1.5 degrees Celsius, with initiatives such as the Bonn Challenge, Trillion Trees Vision and the World Economic Forum’s 1t.org project setting ambitious targets. It’s estimated that new or restored forests could remove up to 10 gigatons of carbon dioxide equivalent by 2050. If you have a patch of wasteland in your local community that is sitting idle, a Miyawaki forest could be one way of doing your bit to help the environment. However, not all forests are equally effective in sequestering carbon. Mature forests of native trees soak up much more carbon dioxide than the monoculture plantations that make up many reforestation projects. As scientists learn more about the role of other factors, such as carbon in the soil, it is increasingly clear that planting the right kind of trees matters as much as the number. Conservation groups stress that Miyawaki forests should not be seen as an alternative to protecting existing native forests. Small, unconnected wooded areas never can replace the large tracts of forest that are vital to so many species — and that remain under threat from commercial plantations and slash-and-burn farming.
