Sustainable Materials Management 47
Sustainable Materials Management SMM is a systemic approach to using and reusing materials more productively over their entire life cycles. It represents a change in how our society thinks about the use of natural resources and environmental protection. By looking at a product's entire lifecycle we can find new opportunities to reduce environmental impacts, conserve resources, and reduce costs. https://www.epa.gov/smm 48
Tracking Life Cycle Impacts of Alternative Solid Waste Management Strategies Instead of looking at the % of material s mass recycled, why not look at the environmental burden associated with its waste management.

How can SMM be utilized in a similar manner as the 75% goal? With the SMM tools discussed, we can model the environmental burden (e.g., carbon footprint) associated for a solid waste management for the State or for an individual municipality. Or we can compare different solid waste management systems? But to track progress over time, what do you compare the environmental burden to? One possible approach, is to compare to a baseline environmental burden. 76
Developing a Baseline for Florida Let s consider the following: The Statute with Florida 75% recycling goal was issued in 2008. Let s use 2008 as our baseline. Traditional Recycling Rate = 28.4% Adjusted Recycling Rate = 41.5% MTCO2E Emissions = - 13.0 million MTCO2E Energy usage = -147 million mmbtu 77

Traditional Recycling Rate = 28.4% Adjusted Recycling Rate = 41.5% MTCO2E Emissions = - 13.0 million MTCO2E Energy usage = -147 million mmbtu We developed a hypothetical waste management profile that would have corresponded to a 75% recycling in 2008 (included some additional WTE). Traditional Recycling Rate = 59.6% Adjusted Recycling Rate = 75.3% MTCO2E Emissions = - 25.9 million MTCO2E Energy usage = -275 million mmbtu Our Target 78

Lessons Learned With respect to two environmental burden categories (GHG emissions, energy), different recycling approaches result in different progress toward the goal. The materials targeted play a major role. The selection of a baseline is critical. Aluminum Cans Cardboard Newspaper Computer Steel Cans PET Plastic HDPE Plastic Glass Asphalt Shingle Drywall 5 0-5 -10 GHG Emissions (MTCO2E/ton) 93
Refined Approach Lets assume a hypothetical waste management profile in 2008, Baseline 2, that follows: Combusted, 25% Recycled, 50% Landfilled, 25% 94
Refined Approach The Baseline 2 outputs: Traditional Recycling Rate = 52% Adjusted Recycling Rate = 77% MTCO2E Emissions = - 25.8 million MTCO2E Energy usage = -272 million mmbtu Our Target To make it easier to compare, we will normalize the GHG and energy burdens to an equivalent progress toward a recycling goal. 95

Discussion SMM could be used as a tool to set alternative targets with respect to solid waste management in Florida. This approach helps identify materials/system targets to reach SMM goals. What is an appropriate SMM metric? Could be community specific. Provides a scientific methodology to recognize WTE and more sustainable landfill practices, but still rewards recycling efforts. Reaching 75% is still a challenge. 102
What is the Appropriate SMM Metric? Metric Greenhouse Gases Energy Consumption Water Consumption Acidification Potential Community decides which is the most important to become the objective metric Objective Metric Baselines Reporting Measurements 103
