Richgro garden products is a family owned and operated business, established in WA back in 1916, and today is a nation wide supplier of compost and fertilisers.
Richgro’s team started researching viable renewable energy options in 2011 to reduce their $600,000pa electricity costs, touring Europe and America looking for the right solution.
They decided on anaerobic digestion.
As a licensed receiver of organic waste streams, predominately green waste from council collections, Richgro have formed a closed loop system, which produces electricity, a bio-fertiliser by-product which can be blended with existing products, heat and CO2 which can be used on-site.
With an input of some 35-50,000 tonnes of food waste available per annum, the anaerobic digestion plant can produce around:
- 2MWe capacity electricity
- 2.2MWth heat for utilization
- CO2 for use within their blueberry hot houses
- 100m3 of liquid bio-fertiliser
