Company HRS Heat Exchangers ‘scraped surface vacuum evaporator’ recently earned them an award at the National Recycling Awards for ‘Best Energy from Waste Initiative.’ The device was installed at an Anaerobic Digestion plant in Barkip, North Ayrshire, Scotland.
The Barkip plant, run by SSE, was opened in May this year and boasts the biggest combined organic waste treatment and energy generating service in the whole of Scotland. It can treat around 75,000 tonnes of organic waste in just one year, and can generate 2.2 megawatts of electricity from using the biogas that is combusted in its gas engines. As well as generating electricity, the heat that is created from this process is trapped and is added to the liquid fraction of the digestate to concentrate into a liquid, which can then be used as an agricultural fertiliser.
The plant makes use of organic matter such as food waste from a range of industries including food retail, food/alcohol production, and agriculture. The waste that is provided then undergoes a process of being broken down by bacteria, which in turn creates the biogas.
HRS is now renowned for demonstrating an innovate resolution for waste minimisation with the success of a good business strategy.
