At the heart of a circular economy is a shift away from ‘take, make, use and dispose’ towards a more circular approach, where the value of our resources is retained for as long as possible. A circular economy reduces reliance on virgin materials, seeks to avoid pollution and waste and runs on renewable energy.
The energy and nutrients of organic material that enter Australia’s waste system can be reutilised within a circular economy for the benefit our soils and enhanced agriculture.
LMS recovers the energy value of organic waste from our ‘red’ or ‘blue’ bins, which is unsuitable for compost as it is contaminated with fine plastics, chemicals and other inorganic materials. For nearly 40 years, LMS has driven the specialised technology and intellectual property required to efficiently convert organic waste into a valuable source of green energy to power our communities. Through this process, LMS avoids over 3.7 million tonnes of carbon entering our atmosphere every year. Our bioenergy capture is the largest source of carbon emission reductions in Australia and is a valuable baseload energy contributor to Australia’s renewable energy mix.
For clean organic waste (ie, our ‘green’ bins) , composting has been broadly adopted to recycle its nutrient values. Additionally, for suitable organic wastes, Anaerobic Digestion facilities that enable efficient capture of both energy (from biogas) and nutrient values are well established overseas and there is opportunity for significant expansion in Australia. Composting and anaerobic digestion produce complementary nutrient outcomes, with composting supporting soil enhancement and digestate forming a fast‑release fertiliser.
Biogas capture and anaerobic digestion can also offer additional heating benefits for horticulture and industry where needed.
LMS will continue to lead in biogas innovation, organically powering the circular economy.
