Richgro digester makes the most out of food waste

 

The anaerobic digestion facility at Richgro was installed by Perth based Biogass Renewables and became operational in 2015.  The considerable investment not only helped the garden business for which Richgro is famous…..but it has also opened up a whole new area of growth.  Richgro is able to provide a service to local food and drinks manufacturers – diverting out of date stock or faulty stock from landfill and using it to generate biogas used onsite to produce heat and electricity – a huge onsite saving for Richgro with the added bonus of being to sell some electricity back into the grid. The waste liquid from the process is nutrient rich and is used in the production of their compost.  In addition, Richgro is able to route much of the waste heat and CO2 from the process to newly constructed glasshouses for growing out of season blueberries.

In 2012 Biogass Renewables secured gents from the  Clean Technology Investment Program (now disbanded). The grant funding was augmented by concessional finance from Clean Energy Finance Corporation (CEFC), and support from the Government of Western Australia under its Low Emissions Energy Fund.  The investment was approximately $8 million and the journey was around 5 years from initial discussions to completion. The Jandakot based plant has the ability to process up to 140 tonnes of food waste per day.
