Department of Life and Environmental Science receives Gold award for Green Impact

BU’s Department of Life and Environmental Science (LES) has received a Gold award for Green Impact, after taking part in the Green Impact challenge back in 2015.

Green Impact Universities and Colleges is an environmental accreditation and awards scheme delivered by the NUS, in partnership with the Environmental Association for Universities and Colleges (EAUC).

It aims to empower people and their departments to take action on sustainability and reward them for their environmental efforts within their workplace. 

The award covers measurable actions relating to topics around sustainability – including communication, travel, recycling, and energy – and the number of actions completed correlates to a Bronze, Silver or Gold Award. 

Main activities included promoting the opportunities that BU offers staff to enhance sustainability, such as water saving, Green Week, and sustainable travel; and the identification and documentation of the five most significant negative environmental impacts and suggestions for solutions in the coming year. 

We would like to congratulate the team and the department on this for their hard work and persistence over the last 4 years.

Pee power (urine-tricity) joins poo power!

Researchers from Bristol University are now working with Akamba Children Education Fund, installing microbial fuel cell technology to generate electricity from urine. This is a massive step in the project, as we will now be generating power from both urine and poo. The microbial fuel cells work by feeding on urine (the fuel) using the biochemical energy that is generated and converted directly into electricity. All that is needed to generate this power is the waste product, making it a sustainable green technology solution. The combination of biogas production, and using microbial fuel cells to use urine and mud to generate power makes the project unique.

Manure Mondays…

On a rainy Monday (05/03/2018) in Kenya, 1000 litres of cow manure arrived on site in barrels and ready to be put into action. The anaerobic biodigester depends on a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen. One of the end products is biogas, which will be combusted to generate electricity and heat for the school. We’re using the manure to kick start the biodigesters in the green toilets which will allow us to convert human waste into biogas.

Along with the arrival of the manure, work on site is making steady progress. The foundations for the structure are now underway which will hold the steel frame structure in place. The skeleton assemblage of the structure has also began, with steel beams being welded together off site. The next step is to get the structure to the site…
