On this visit, rather than seeing a garden, we will be concerned with the environment more generally and managing the Earth’s resources. We will tour the Ardley Energy Recovery Facility, which began operation in 2014, treating up to 326,300 tonnes of non-recyclable waste each year. It diverts at least 95% of Oxfordshire’s residual municipal waste away from landfill and generates enough electricity to power the equivalent of 60,000 homes. The state-of-the-art visitor centre is designed to teach interested adults about sustainable waste management and how energy recovery fits into the waste hierarchy. Visitors should be able to walk approximately a mile over uneven ground. Wheelchair users are welcome but they will only be able to do half the tour. Refreshments on arrival.
