GESS RNG Biogas announces new projects, manure collection process
The process, which GESS RNG Biogas’s teams have been working on since 2018, reduces the amount of manure fed into lagoons and significantly increases efficiency. Compared to the traditional covered lagoon system, anaerobic digesters not only improve gas production efficiency, but reduce odour and atmospheric pollution from escaping gases; cold weather production loss, limitations on material processing, and wet waste.
GESS RNG Biogas will implement its collection system at two biogas plants in North Carolina. The Union County facility can accept swine manure, poultry litter, food processing by-product, and agricultural crops as feedstock. This plant is designed to produce up to 200,000 MMBtu of biogas annually initially, scaling up to 500,000 MMBtu per year.
The Bladen County plant will collect swine manure and poultry litter from surrounding farms, with initial production estimates between 160,000 and 200,000 MMBtu of biogas per year, scaling up to 500,000 MMBtu per year.
GESS RNG Biogas is also finalising two dairy projects. The first, in Grand Rapids, Michigan, will produce up to 150,000 MMBtu of biogas per year. The second, in Syracuse, Kansas, will produce up to 300,000 MMBtu of biogas annually.
As initially reported in mid-December, the firm’s sister company, Cyclum Renewables will install renewable microgrids on all projects. These will allow sites to utilise RNG, biodiesel, and EV trucks, which can be fuelled on-site while producing each plant’s electricity. This will help to minimise the carbon intensity score of each plant. Cyclum has agreed to offtake some of the RNG for use in fuel production at its planned renewable fuel truck stops.
