Power of Place questions for communities
What information would be of the most use to your community in your community discussions about how to transofrm your food scrap into a resource for the revitalization of the community.
Uses of compost
How much compost is used now in the community? Where does compost used now come from? Places to get info. Town government, landscapers, stores
How much could be used? Agricultural potential of the community? USDA?? Landscapers?
Would the quality of the compost effect its uses? How?
Costs of compost?
How would a local source effect use?
Would a local source reduce carbon footprint?
What percentage of the food scrap feedstock is amenable to home composting?
What part of the food scrap feedstock can not be safely and properly composted at home/home much of it will need to be picked up.
What percentage of the population is amenable to home composting
What percentage of the population will actually do home composting with or without the option of collection for a centralized facility
Providing information and resources to help people make good choices for their situation
Where does yard waste fit in?
Getting rodent proof composting units into the hands of home composters.
The costs involved in education about home composting and providing the right tools
Community Collection from households
How much food scrap is available in various communities (8 ounces per person per day is US average)
How much material for composting is available within 5 miles, 10 miles, 15 miles
What percentage of the population will put out compostables/practice proper separation
How much can this be boosted by education/publicity
What the current collection system looks like and what it costs. The trucks used, the miles driven, the fuel consumed, the time involved for each separate collection (currently trash and recyclables) and their costs.
What technologies for accumulation and collection are available/what are the costs/who might invest in collection (bins, trucks, kitchen collection systems, biobags, etc)
Public or private?
Can we overcome the yuck factor
Must separation be mandatory or will there be sufficient compliance/reliability of supply for a high tech compost facility without making it mandatory?
How much of the food scrap feedstock will still end up in the landfill and for what reasons.
What political obstacles must be overcome/ can sufficient political organizing and data collection and dissemination take place to overcome resistance
Home collection or collection depots? Difference in collection rates?
Can this fit in with current systems collecting leaves and yard waste
How does this fit with community recycling efforts
Contamination issues, trash and chemicals
Is free compost for households and agriculture an important part of the equation?
Can the community plan a good roll out
Amount spent municipally on tipping, dollars and tons.
Amount spent on collection with breakdown of routes/miles/recycling routes
Costs per ton mile??
Costs of Leaves and yard waste collection systems and composting facilities where applicable
Can reduced tip fee costs be channeled to a separate collection or techno fix to collect separately on the same truck.
What are the costs for transformation, roll out and implementation
Amount of commercial food scrap available in each community
How that effects the sizing of facilities
Regulation of commercial food scrap disposal
What capacity is needed in Providence, metro area, RI
Sources of browns to mix in?
How many truckloads a day is that? Greens/Browns can we store sufficient browns in the fall for the year?
Statewide there are 500,000 pounds a day of food scrap, 250 tons of food scrap compostables year round
Approxiately same amount for Browns are also available
That would produce approximately 200000 lbs of compost, 100 tons per day
Providence 90,000 pounds a day, 45 tons, of food scrap
Location, location, location
Cost effective haul distances and population centers, tourism spots
Type of facility? Anaerobic digester? Open windrows, Aerobic compost machines,
Cost of each kind of facility and the various scales that can be economical for each.
Footprints for each type of facility
Products Compost Heat and compost, Electricity heat and compost, Food electricity heat and compost?
Most efficient size of facilities/matched up with amount of food scrap available within a given distance?
Operational Costs so that one could determine tipping fees needed to run the facility and compare to alternatives
Potential revenue streams given the different outputs (to determine ) what would be the best mix and what system would be needed to distribute compost (sales, free to community, or some mix of these?)
Job creation potential construction/operations/ancillary in community
