New Zealand’s Ecogas to collect food waste for biogas production to heat greenhouses

July 16, 2019 |

In New Zealand, the announcement that Ecogas will collect central North Island food wastes and process them at Reporoa into energy and bio-fertilizer will provide an example that all communities across New Zealand could follow, said the Bioenergy Association. The Bioenergy Association has identified that 1.8 million metric tons of CO2-e of greenhouse gases could be reduced if this type of project was extended to other food processors and communities.

“The production of biogas from the waste will allow the generation of electricity, provide hot house heating, produce high value bio-fertilizer, and provide carbon dioxide for enhanced plant growth in the hot houses. These are valuable products which will reduce T & G Global’s horticulture operating costs and increase productivity. This is on top of the avoided cost of disposing of organic wastes from the site, as well as those communities who have contracted to supply organic waste instead of disposing of it into landfills,” said the association’s CEO.
