COMPOSTING ALTERNATIVE MATERIALS: REGULATORY REVIEW & APPROVAL PROCESS REGULATORS ROUNDTABLE USCC 17 TH ANNUAL CONFERENCE HOUSTON TX JANUARY 27, 2009 Division of Solid & Infectious Waste Management
Why Alternative Materials? Increased interest by generators seeking to reduce waste disposal costs Compost operators need incoming materials Attain state’s waste diversion goals Alternative to a beneficial use regulatory program
Ohio’s Approach Composting rules allow certain facilities to request approval Rule language Information required for review Criteria for approval
Review Goals Good understanding of what the material is Technical feasibility Operator readiness
Understanding Material Clear description of process that generated waste Single waste stream or commingled wastes? Kinds of contaminants expected? Historical and current analytical test results Fairly consistent? Can it meet any applicable compost quality standards? Is the material compostable/biodegradable? Physical characteristics (i.e. dusty, sludge-like) Other?
Technical Feasibility Has it been done before? Does available literature suggest it might work? Does the compost methodology makes a difference? Does it as value to composting process?* Other? *More on this later!
Operator Readiness Are they fully aware of how to handle this material? Is the facility adequate for handling the material? Leachate control Capacity Do they have the right equipment? Do they have enough experience? Other?
Sources of Information Literature search Research databases Outside experts (academia, testing laboratories) Other operators Peers (intra & inter agency, other states)
Value to composting process If not clearly a feedstock or bulking agent, what other value does it add? Fertilizer value (nutrients, micronutrients) Soil-like minerals? (i.e. anion/cation exchange) Balances pH Promote microbial growth or action (i.e. clay) Make compost more soil-like
