The greater Boston area produces 270,000 metric tons of of food waste per year, 97% of which goes to landfills and incinerators. To address this nutrient inefficiency, the decommisioned South Weymouth Naval Airbase is reconceptualized as a regional nutrient cycling center. Regional composting operations, located on the existing western runway, are supported by adjacent wetland, forest, and grassland systems. Topographic manipulations control water flows as well as providing discreet spaces for livestock grazing and processing, grassland birds and wetland species.
Nutrient cycling takes place on a regional level and on the site scale as part of daily operations. 300 metric tonnes of organic waste per year are transported by rail from the greater Boston area. This organic material is taken through a 90 day multi-step process until it becomes nutrient-rich compost which contributes to the vitality of the soil on site and in the region. Additionally, the livestock play an important role in nutrient cycling through the manure they deposit in the soil and meat and milk products distributed to the region.
