The Environmental Protection Agency (EPA) has published National By-Product Criteria for Greenfield Soil and Stone.

These criteria allow for the classification of greenfield soil and stone as a byproduct, meaning the material does not become waste. Keeping materials in use is one of the fundamental elements of a circular economy and enable useful soil and stone materials from one site to potentially be reused for landscaping, reprofiling of land and other similar uses.

David Flynn, director of the EPA’s Office of Environmental Sustainability, said: “Construction is the largest generator of waste in our country, in the region of 9 million tonnes annually with the bulk of this being soil and stone waste. Embracing new approaches to design, materials choice and modern methods of construction will shift the sector onto a more sustainable path.

Reuse of useful soil

"Today, the EPA is streamlining the regulation of construction materials to promote the reuse of useful soil and stone that would traditionally end up as a waste. This opens up more opportunities for safe reuse, and offers greater regulatory certainty to the industry and stakeholders while ensuring appropriate safeguards remain in place.”

The European Waste Framework Directive puts a priority on construction and demolition waste. Construction activity comes at an environmental cost, putting pressure on our natural resources, biodiversity, and generating significant waste quantities. The scale of wasted resources and materials in the construction sector needs urgent attention. 

Warren Phelan, programme manager of the EPA’s Circular Economy Programme, said: “These criteria present a real and meaningful opportunity for the construction sector to follow a simple set of rules and in doing so reduce soil waste from sites and make tangible savings. These latest criteria are the third in a series of national decisions introduced by the EPA to support improved material circularity in the construction sector.”
