Waste Reduction and Diversion
Reducing the generation of waste and diverting recoverable materials from disposal.
The Solid Waste Management Act establishes a waste reduction goal (RSA 149-M:2) and a hierarchy or preferred waste management methods (RSA 149-M:3) in order to encourage and support an integrated system of waste management that reduces the generation of waste where possible, while also managing the waste that is generated in the most environmentally-responsible manner available. While the Solid Waste Management Act does not establish waste reduction or recycling as mandatory practices in New Hampshire, the statute does encourage management of wastes in accordance with the Waste Management Hierarchy and discourages disposal of recyclables by landfilling or incineration.
New Hampshire’s Waste Management Hierarchy
New Hampshire’s Waste Management Hierarchy provides a standard of preference for management of solid waste in the state, with priority placed on approaches that reduce the generation of waste or divert recoverable materials from disposal in landfills or incinerators. Source reduction (that is, reducing generation of waste at the source) is at the top of the hierarchy because such practices prevent waste from being generated, which results in less waste needing end-of-life management, conservation of resources, and reduction in overall environmental impacts. Of course, it is not always feasible to reduce or prevent waste from being generated. Therefore, the next preference on the hierarchy is diversion. The concept of diversion includes management methods that recover discarded materials so that they are reused or repurposed instead of disposed in a landfill or incinerator. This includes methods such as recycling and composting. Next on the hierarchy are waste-to-energy technologies, including incineration with energy recovery, anaerobic digestion, and emerging conversion processes that turn waste into fuel. These technologies are preferable to traditional disposal methods because they can recover energy, reduce volume and weight, and in some cases produce useful by-products. Meanwhile, traditional disposal methods such as landfilling and incineration without energy recovery have lowest preference on the hierarchy and should be reserved for wastes that cannot be source-reduced or diverted.

Turning waste into usable products
A waste-derived product is a material or item which is produced, in whole or in part, using materials or items which are recovered or diverted from the solid waste stream. Waste-derived products must be certified for distribution and use in New Hampshire. Production, use, and distribution of a certified waste-derived product may be subject to specific terms, restrictions, and specifications.
Solid waste strategic goals and objectives
The New Hampshire Solid Waste Management Plan contains strategic goals and objectives for management of solid waste in the State that support and uphold the provisions of the Solid Waste Management Act (RSA 149-M).
Assessing progress toward New Hampshire's waste reduction goals
The Biennial Solid Waste Report provides information about the State’s waste reduction goal established by RSA 149-M:2, as well as other details related to solid waste management in New Hampshire.
Improving environmental practices and ensuring regulatory compliance
Motor vehicle salvage yards play an important role in recovering and recycling end-of-life motor vehicles. Up to 85% of the material in motor vehicles, by weight, is recyclable. NHDES provides industry specific Best Management Practices to motor vehicle recyclers to help improve environmental practices and maintain compliance at their facilities. The program also works closely with municipalities to facilitate appropriate licensing and oversight of these important facilities within their communities.
