Vermicomposting is the ideal technology for wet organic wastes such as sludge and semi dewatered materials. Worms require a moisture content between 60% and 90% depending on the structure of the ‘feedstock’. At MyNOKE® we are combining wet resources with semi moist materials. Sludge with no structure will be mixed with carbon rich fibre to provide the structure compost worms require.

Yes – with some limitations though as anaerobic digestion is reducing the carbon content in the organic waste but increases nutrient content such as nitrogen. High amonia concentration in the digestive can be toxic to earthworms. At MyNOKE® we are buffering the nutrients with fibrous resources to balance nutrient and fibre for the wellbeing and performance of our earthworms.

At all MyNOKE® vermicomposting operations together we are vermicomposting 150,000 tonnes of organic resources per year and are steadily growing. The largest sources of organic materials are some 95,000 tonnes per year from one of our clients. In addition we are receiving 15,000 tonnes of anaerobic digested sludge and 21,000 tonnes of waste activated sludge from other individual customers.

The smallest municipal ‘worm farm’ we are operating is at Maketu with approximately 250 tonnes biosolids intake per year.
