Jasper Hill Farm has just designed and constructed a nutrient recovery system as an innovative approach to waste management. Our 'Green Machine' is an enclosed, integrated, biological treatment system for managing the manure, whey, and wash-water from the barn and creamery. This three-prong system employs Aerated Composting of manure solids, Anaerobic Digestion for primary liquids treatment, and an Advanced Botanical System for secondary liquids treatment.
Essentially, this system gleans value-added compost, clean irrigation water, and heat energy (to replace fuel-oil for the creamery boiler) from previously burdensome waste materials. A heat recovery system pulls warm air from developing compost to keep a greenhouse warm year round. In turn, the greenhouse supports the botanical filtration system as well as some vegetable production. Plus, the ability to irrigate pastures means a longer grazing season in a wintry climate.
