MRF Glass Used as Alternative Daily Cover

July 12, 2023

The Northeast Recycling Council (NERC) has released a report that reveals data about post-consumer recycled glass containers being used at landfills in the Northeast states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Vermont) and Quebec. NERC’s Glass Committee compiled the Recycled Glass Used as Alternative Daily Cover in the Northeast US & Quebec Report to get a better understanding of the volume of recycled glass containers coming out of Material Recycling Facilities (MRFs) that never reach manufacturers for making new products, but are instead used as Alternative Daily Cover (ADC)—cover material placed on the surface of the active face of a municipal solid waste landfill at the end of each operating day.

“The Report provides great insight into MRF glass that is not reaching manufacturers for making new products and is instead being used at landfills—the lowest value end use with the least environmental benefits,” said Mary Ann Remolador, Assistant Director of NERC and Glass Committee staff lead.

One of the key findings is that 75% of the states/province reported that post-consumer glass collected for recycling is being used as ADC. These states include Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Quebec. The glass being used for ADC includes crushed recycled glass that is broken into pieces too small for manufacturers to use in their processing, non-bottle bill glass, and glass meeting the state’s specifications for ADC. The states not using glass for ADC are Delaware, Maryland, and Vermont. 

One of the contributing factors for glass being used as ADC is the poor quality of glass coming from MRFs. It is oftentimes considered too dirty or contaminated for use in manufacturing. The contamination is due to the glass being mixed with other recyclables at the MRFs. In addition, many Northeast US MRFs aren’t equipped with the necessary systems for removing glass at the beginning of the sorting line. This contamination adds weight to the glass, which makes the cost of shipping long distances impractical.   

The Northeast US also lacks enough beneficiation facilities that accept MRF glass to serve the entire region. Beneficiators clean and process glass, making it into a feedstock for manufacturers. Without these facilities, the region’s contaminated MRF glass has no viable market within a practical shipping range. As a result, many MRFs are sending their separated glass to landfills for ADC.

Another key finding from the report is that only 58% of the states/province have data about the tonnage of MRF glass used as ADC. These include Delaware, Maryland, Massachusetts, New York, Rhode Island, Vermont, and Quebec. 

Additionally, 76% do not recognize post-consumer glass used for ADC as recycling (Connecticut, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Quebec), and 83% require post-consumer glass to be recycled. Maryland and New Hampshire do not require it.   Also, Massachusetts, Pennsylvania and Vermont (25%) are the only states/province that have post-consumer glass disposal bans.

The report also shows that transparency with the public about what happens with post-consumer glass could be improved in most states. While some states take a proactive approach to ensuring end uses for recycled material are publicly available, others do not readily share this information. 

After a thorough analysis of the compiled information, NERC and its Glass Committee drew the following conclusions:

  • Until more investment is made in the glass recycling infrastructure, MRF glass will continue be used as ADC.
  • Without having consistent outgoing materials reporting requirements for MRFs, it’s impossible to generate data about the total tonnage of recycled glass diverted for use as ADC in the Northeast region.
  • More beneficiation facilities capable of cleaning MRF glass are needed throughout the region to make the glass economical for use as a manufacturing feedstock.

The Northeast Recycling Council (NERC) is pleased to announce the release of the 2026 Northeast States Policy Guide , a new regional resource that provides a comprehensive comparison of sustainable materials management policies across eleven Northeast states. “The guide serves as an excellent primer for state and industry stakeholders looking to learn about the various policy frameworks enacted across the northeast and how they have been applied.” said NERC President, Michael Nork, Environmental Analyst, New Hampshire Department of Environmental Services. Developed through a standardized survey of state government agencies, the guide serves as a practical reference for policymakers, municipal leaders, industry professionals, and researchers seeking to navigate and compare policies related to waste reduction, reuse, recycling, and circular economy initiatives. The publication includes both regional policy analyses and detailed state profiles covering product bans, product stewardship (including Extended Producer Responsibility), minimum post-consumer recycled content requirements, mandatory recycling laws, and disposal bans. “This resource provides high level insight into materials of interest that the Northeast has focused on managing for decades. For a regulatory agency, specific resources that provide clear examples of replicable or considerable policy and management strategies are useful tools--having them in one place is even more valuable.” said Shannon McDonald, Waste Diversion Division, Director at Maryland Department of the Environment. Key Findings The guide aggregates state-level data across Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont to highlight core regional policy trends: Regional Policy Prevalence: Regulatory frameworks are widely established across the region, with 10 of 11 states using product stewardship programs, 10 enforcing disposal bans, and 9 maintaining mandatory recycling laws. Broadest State Coverage: Maine and Vermont regulate the widest variety of items in the region, 20 and 21, respectively, distinct material categories through state policies, followed closely by New Jersey at 19 categories. Top Regulated Materials: Electronics are the most widely addressed material (regulated by 10 states), followed by mercury thermostats (9 states), tires (8 states), followed by paint, rechargeable batteries, beverage containers, fluorescent lighting, lead-acid batteries, mercury-added products and yard waste (7 states). Funding & Mechanism Structures: Among the region’s product stewardship programs, 47% are producer-funded, 15% rely on consumer point-of-sale eco-fees, 5% combine producer and consumer fees, and 33% utilize alternative measures such as labeling, recyclability standards, or disclosure requirements. Regulatory Gaps & Emerging Opportunities: Significant policy gaps exist in rapidly growing clean-energy waste streams. Currently, only 1 state addresses electric vehicle (EV) batteries, and zero states have statewide policy programs for solar panels. Unfilled coverage areas present distinct opportunities for cross-state collaboration, policy alignment, and regional innovation. By presenting data in a standardized format for each state, the guide enables stakeholders to easily compare regional policy approaches, identify coverage gaps, and adapt proven regulatory models. "By standardizing how we measure product stewardship, PCR mandates, and disposal bans across all eleven states, this guide allows state leaders to quickly identify where their policies align with neighbors and where transferrable models already exist," said Mariane Medeiros, Director of Strategic Engagement and Sustainability Programs at NERC. "With 10 of 11 states enforcing stewardship programs and disposal bans, the region has proven its ability to manage complex products. The next frontier is applying that same collaborative momentum to rapidly growing clean-energy waste streams like solar panels and EV batteries." Alyssa Eiklor, Board Member and Environmental Analyst at Vermont Department of Environmental Conservation, cited: “The NERC Policy Guide provides a valuable comparison of the similarities and differences in how northeastern states use policies as a tool for waste management. It also serves as a convenient short cut for linking directly to the policies.” The full 2026 Northeast States Policy Guide is available for download at: https://www.nerc.org/state-policy-guide About NERC The Northeast Recycling Council, Inc. (NERC) is a multi-state nonprofit organization committed to minimizing waste, conserving natural resources, and advancing a sustainable economy through collaboration and action. NERC's eleven member states and advisory members work together to address sustainable materials management challenges and promote solutions across the Northeast region.
