Year 6 Geography Field Trip – Sustainable development

How do we balance our needs with those of the environment?  Year 6 have been exploring ways in which we can do that in both urban and rural settings and our trip to an Anaerobic Digester (AD) and Solar Farm in Codford helped us to see how we generate energy from sustainable sources.  The AD takes food waste, removes packaging (to recycle) and uses bacteria in large anaerobic digesters to turn the waste, otherwise headed for landfill, into methane gas.  The gas is burned to generate electricity for the National Grid – even the exhaust gases are captured to create electricity!  Another waste product from the process is ‘digestate’, a nutrient-rich fertilizer that is used on the farm to fertilize the fields through a series of lagoons and pipes.  In another part of the farm, fields have been turned over to solar panels, which also generate electricity for the National Grid.  Not only does this reduce our carbon emissions, it provides sustainable habitats for wildlife.  The children took copious notes on the trip and produced an eye-catching display on the topic for our geography classroom.
