The project will result in recycling of sizeable amount of nutrients, reduction of fuel consumed for transportation, establishment of large forest area and significant amount of carbon sequestration in biomass and soil carbon storage:
– 550 t/year of CO2 emissions reduced due to saving over 200 thousand l of diesel due to twice shorter transportation distances and due to three times lower sludge volume comparing to 30% dry solids digestate transportation
– 180 t/year of CO2 emissions reduced due reuse of nutrients from MWTS (reduces CO2 3,6 t per 1 t of N of mineral N (N03 + NH4) reused and reduces CO2 1,8 t of 1 t of P of plant available phosphorus P205 reuse) , which is minor, comparing to total N and total P reuse (reduction of 1800 t/year of CO2)
– 4 t/year of CO2 emissions reduced due reuse of nutrients from biomass ashes (reduces CO2 0,8 t per 1 t of K of plant available phosphorus K20 reused) , which is minor comparing to include total K and total P reuse (reduction of 25 t/year of CO2)
– 4500 t/year of organic C added to soil and stored (equivalent 16500 t/year of CO2 stored) due amending soils with bio-solids (dried MWTS digestate)
– 32940 t /year of CO2 sequestrated within all CE demonstration model by aboveground biomass annual increment (10 dmt/ha/a)
All above listed values do not include CO2 sequestration in bellow ground biomass values and C increase in soil due to green biomass littering and do not include CO2 emissions from biomass plantation establishment, nutrient rich waste recycling, biomass plantation management, harvesting and transportation to biomass boiler. All the data will be estimated during LCA preparation.
