The Botanic Garden’s own biomass boiler helps to warm the Great Glasshouse, offices, shops and catering facilities. It currently burns factory waste chippings and shavings that would probably end up in a landfill site if they didn’t come here. Eventually we hope to use coppiced willow and poplar, which is being grown on an adjacent field, or some of the new variety of biomass plants that are being grown in demonstration beds next to the bioler.

In early 2012, we updated the boiler to make it more efficient and effective. To read more about this, click here.
