Taskforce Meeting
March 4, 2011
Focus on food waste Also other organics such as leaves and
yard waste and agricultural wastes Food waste about 15-20 % of disposal –
just over 1 million tons /year from Massachusetts
Has value first as food Then can be used to create compost,
soil amendment, fertilizer, and clean, renewable energy
Reduce total disposal by 2 million tons/year by 2020 (30 percent reduction in disposal tonnage)
Capture additional 350,000 tons per year of food waste (about 35% of generation)
Develop at least 250,000 – 300,000 tons per year of processing capacity and supporting collection infrastructure
Increase percent of energy need met by renewable sources
Reduce GHG emissions Support farms by providing additional
energy and revenue source & manure management option
Increase energy production and revenue at wastewater digesters
Windrow composting In vessel aerobic composting Anaerobic digestion – various
technologies Outputs can include compost, soil
amendment, liquid or solid fertilizer and heat/electricity
Farm-based and commercial food waste capacity (100,000 tons per year)
2010 – 70 composting operations registered with DAR
200 additional leaf and yard waste compost sites – municipal and private
Five active wastewater digesters Industrial AD operations
six agricultural anaerobic digesters – two scheduled to begin operations by summer 20113-5 year timeline to develop220-480 kw generatorsGenerate fertilizer and bedding material
Also significant commercial and wastewater facility proposals
Nearly 300 supermarkets recycling/composting
Convention center and hotels composting projects
Pilot projects for residential and school composting
Large commercial generators (food processors, colleges/universities, large businesses)
Work with targeted generator sectors to increase diversion
Residential and school collection programs Renewable energy incentives Targeted grants and loans for capacity
development Integrate food waste into wastewater
treatment digesters Clarify and better enable the development
of facilities using these new management technologies while ensuring proper oversight
Waste ban by 2014
Capturing valuable resource that can improve soil quality, reduce runoff, and conserve water
Generate clean renewable energy Support jobs and economic
development in Massachusetts Provide cost effective material outlets
for businesses, institutions, and municipalities
Support viability of farms by providing energy, soil materials and alternative revenue source
Increase the efficiency ad reduce costs at wastewater treatment plants
Reduced need for landfill capacity (which will decrease over time)
