Learn to build an anaerobic digester: ‘Build a Micro AD weekend’

tjmscjo15 October 2015

The third ‘Build a Micro AD weekend’ (3rd & 4th October)

Last weekend we had another sunny couple of days working on the project. Our engineer, Guy, delivered the digestor and prefeed tanks and the focus for the weekend was to finish the housing for the tanks, and to design the internal layout for all the systems that will be housed in the shipping container and make up the anaerobic digestor.

Bringing rural to urban: community energy and closing ecological loops in the city

ucfugor23 July 2015

Posters ready for the session at the German Deli in Hackney WickBeing interested in researching the often complex motivations behind community energy projects and the ways in which they develop and come to be, as well as being a firm believer in the potential contribution of localised urban energy production for moving towards a low-carbon transition, I was excited to learn about project developed with the London strand of R-URBAN, R-Urban Wick by UCL’s Institute for Sustainable Resources and art and architecture practice public works.

R-URBAN is a grassroots venture, aiming to enhance urban resilience by initiating closed ecological cycles, embedded in a local context. This could for example be achieved by re-localising (and thus “ruralising”) patterns of production and consumption within the city. And, by searching for alternative uses for the by-products of production which may otherwise be disposed of unnecessarily, their status could be transformed from waste product into alternative product, simultaneously creating economic, social and environmental benefits. With landfills close to being full, Londoners and city-dwellers elsewhere will no longer be able to ignore the waste issues that city life produces, so it is a great time to be thinking about ways in which we can divert and utilise the by-products of our consumptive habits.

Investments in Resource Efficiency: Understanding benefits & overcoming barriers

Resource efficiency investments tend to yield both economic and environmental benefits, yet many low- and middle-income economies lag behind. The main causes of inefficiency are market failures and distortions, which create barriers preventing firms and governments from investing in efficiency. Comprehensive strategies are needed to address the complex and interlinked causes of inefficiency.

High and volatile resource prices, uncertain supply, rising demand and environmental impacts – various factors are putting increasing pressure on policy makers, researchers, firms and investors to explore pathways towards sustainable and efficient resource management. Resource efficiency is considered to be an answer to these challenges, yielding substantial benefits – both environmentally and economically. (more…)
