Frequently asked questions

  1. How much waste will be processed by the Westry site?
    The plant will be able to process 30,000 tonnes of waste per annum.

  2. What kind of waste will you process?
    We will handle waste output from agriculture, manufacturing and retail; from meat, dairy, vegetables, baked goods and processed foods both solid and liquid. And whatever the product, we can effectively deal with all forms of packaging.

  3. What are advantages to our business of using anaerobic digestion as a method of disposing of our waste?
    With the increasing commercial and environmental cost of using landfill, anaerobic digestion offers you a viable, ethical and regional alternative. Local Generation will reduce the amount of methane entering the environment; this is great news as methane is 20-25 times more damaging to our environment than CO2. The green energy Local Generation will generate will further cut CO2 emissions that would otherwise be generated by fossil fuels.

  4. Which categories of meat materials will you be able to process?
    We will be able to process Category 3 animal by-product materials

  5. How does the Anaerobic Digestion Process work?
    Anaerobic digestion works on very similar principles to human and mammal digestion. At the plant, food is shredded and liquefied in a similar process to chewing and swallowing. Food and liquid are then mixed in the AD Hydrolysis tank, which acts like a giant stomach. The mixture passes through pipes (the equivalent of human intestines) for further processing in the Digester tank, where the temperature is maintained at a steady 50°C, producing generous amounts of biogas. This biogas will be captured and used to power generators, producing electricity for 1500 homes.

    Finally, the AD process also generates both solid and liquid products. The solid output, called digestate, makes an excellent soil improver. The liquid, thoroughly cleaned, will be recycled back into the AD process. It is this diversity of uses that makes AD such an efficient way of handling waste food.

  6. How will our waste get to your Local Generation plant?
    We can work with your current waste handlers and ensure that the process is seamless for you. However, if you have different requirements we would be happy to discuss these with you in more detail. Together we can work out the best options for your business.
