Project Description

Organic waste management presents challenges and opportunities alike for community-based economic development. Waste-to-compost transformation can be socially and economically successful by employing ecological design principles, multistakeholder collaboration, and values-based supply chains (VCs). An analysis of commercial buyers’ preferences for compost will inform approaches to forming effective partnerships of public, private and nonprofit stakeholders to develop a market for local waste resource products.

Recyclable organics refers to ‘green’ organic wastes such as leaves, tree prunings, and shrubs from household yards, parks and gardens, and road reserves. Commercial wet organics includes organic wastes from the agriculture, and food processing industries such as manures, wool scouring wastes, grape marc, animal carcases, and biosolids. Domestic food waste is the food fraction of the waste stream generated by households.

Domestic residual waste refers to the residual waste placed by householders in the garbage bin after source separation has occurred. For all organic processing industry scenarios considered, it is assumed that domestic residual waste does not include paper, cardboard, and plastics which are source separated by householders for kerbside recycling.
