Policy and Program Impact Estimator: A Materials Recovery Greenhouse Gas (GHG) Calculator for Communities

EPA developed a calculator that expands the Waste Reduction Model (WARM) framework to include a community’s existing waste stream and policy and program options. This Excel spreadsheet calculator is designed to help municipalities, counties, and tribes estimate reductions in life cycle GHGs from implementing new or expanded solid waste policies and programs in their communities.

Using EPA’s WARM version 14 emissions factors, the calculator generates projected results for annual and accumulative tons of waste diverted and GHGs reduced over a 10-year planning timeframe. The results can inform comparisons of the estimated GHG impact from implementing different policies and programs, consistent with user-entered assumptions.

Materials addressed by the calculator include metal, glass, plastic, paper, wood, food waste, yard trimmings, and various construction and demolition debris materials. The calculator may also serve to familiarize users with what type of local solid waste data is needed to estimate GHG reductions from recycling and composting programs.

Do We Have the Right Performance Indicators for the Circular Economy?: Insight into the Swiss Waste Management System

Haupt, M., Vadenbo, C. and Hellweg, S. (2016), Do We Have the Right Performance Indicators for the Circular Economy?: Insight into the Swiss Waste Management System. Journal of Industrial Ecology. doi:10.1111/jiec.12506 [Open access article]

Abstract: A material flow analysis of the 2012 Swiss waste management system is presented, highlighting the material content available from waste. Half of municipal solid waste (MSW) is materially recycled and the other half thermally treated with energy recovery. A key component of an industrial ecosystem is increasing the resource efficiency through circulating materials. Recycling rates (RRs), an indicator for the circulating behavior of materials, are often used as measure for the degree of circularity of an economy. This study provides an in-depth analysis of the recycling of paper, cardboard, aluminum, tinplate, glass, and polyethylene terephthalate (PET) from MSW in Switzerland by splitting the RRs into closed- and open-loop collection rate (CR) and RRs. Whereas CR refers to collected material that enters the recycling process, RRs measure the available secondary resources produced from recycling processes. For PET, the closed-loop CR of 45% and the open-loop CR of 40% compare to an RR of 31% and 37%, respectively (including exports and recycling of polyethylene and metals from collection). Official collection rates for paper and cardboard are very high (97%), whereas CR of 74% and 89% and RR of 59% and 81% for paper and cardboard, respectively, were found in the present study (including export). For a majority of the separately collected materials investigated, the rates that are determined are substantially lower than those that are officially communicated. Furthermore, given that official rates often do not provide information on the availability of secondary materials, the improvement potential for increased resource recovery is hidden.

Why sustainability metrics fail to measure achievement, and how to fix them

Read the full post at GreenBiz.

Most major corporations have adopted public reporting to communicate their performance in moving to sustainable management of their business. These reports reveal the companies’ total impact in terms of resource consumption and waste generation as well as normalized versions that attempt to convey corporate improvement in using resources and reducing wastes.

Companies strive to reduce their overall environmental footprint regardless of their overall growth, but the normalized version of the metrics are used to portray their actual efficiency. A growing company might increase its total water consumption but still claim improved efficiency by showing a reduction in water consumption per unit output. The claims based on this type of metric (overall average intensity) generally have been accepted at face value.

Closer examination, however, reveals that overall average intensity seldom, if ever, provides an accurate measure of corporate improvement in efficiency.

Why Measuring Waste GHG Emissions Matters

Read the full story in Environmental Leader.

Accounting for greenhouse gas emissions from waste isn’t as straightforward as, say, measuring those from corporate fleets. But as stakeholders increasingly demand companies reduce their carbon footprint — and firms seek zero-waste accreditation — tracking and disclosing waste GHG emissions is key.

To help companies track more accurate data on GHG emissions from their trash, waste management startup Rubicon Global has teamed up with data company Trucost.

New Waste Tracking Feature Helps Building Managers Save Money and Support a Healthy Environment

The U.S. Environmental Protection Agency (EPA) unveiled today a waste and materials tracking feature in its Energy Star Portfolio Manager, which is a free benchmarking and tracking tool for commercial building owners and managers. Reducing waste and reusing materials more productively through sustainable materials management over their entire lifecycles conserves resources, helps communities remain economically competitive and supports a healthy environment.

EPA’s Energy Star Portfolio Manager is already used to measure energy, water and greenhouse gas metrics in more than 450,000 U.S. buildings, representing over 40 percent of U.S. commercial space, as well as in more than 10,000 buildings in Canada. Now owners and managers using Portfolio Manager will be able to benchmark 29 types of waste across four different management metrics alongside their existing sustainability management indicators. Types of waste include building materials, glass, paper, plastics, and trash.

Currently, U.S. commercial buildings and manufacturing activities are responsible for as much as 45 percent of the 150 million tons of waste in the United States that ends up in incinerators or landfills each year. The transportation, decomposition, and burning of this waste generates greenhouse gas emissions and other air pollutants.

The addition of waste tracking is the culmination of a year-long collaboration between EPA’s Energy Star and Sustainable Materials Management programs and members of the industry to identify key performance metrics for waste and materials management.
