green waste/biochar co-composting project update
Goals & Objectives
Demonstrate the techno-economic benefits of incorporating biochar into a green/food-waste C.A.S.P. (Covered Aerated Static Pile) composting process
Measure over the course of the composting cycle:
- Non-methane VOC (Volatile Organic Compounds) emissions during C.A.S.P. and curing phases
- C/N ratio of compost
- Nutrient availability, salt and chloride content of compost
- Parameters to assess stability and maturity of compost
Benefits to Business:
- Reducing VOC emissions would enable higher permittable facility throughput and increased tipping fee capture
- Lower C/N ratio increases the mineralizable nitrogen content of the finished compost, reducing the need for chemical fertilizers
- Reducing salt and chloride levels in the finished compost for a better performing and higher-value end product
- Faster composting enables shorter curing time and reduced site inventory
