Carbon offsetting firm Carbon8 Aggregates has said the Environment Agency’s decision to approve its new carbon-negative aggregate product is a “game changer” with huge implications for the UK’s construction sector. The product, which is made from flue gas emissions from energy-from-waste plants that are transformed into carbon-negative aggregates, has been granted an end-of-waste status, meaning it can be marketed and sold as an aggregate. Carbon8 Aggregates said the product can replace primary quarried aggregates, reducing the carbon footprint of construction projects. The company said it could be used in road and path construction, flooring, pipe bedding and the production of precast concrete blocks. Each tonne of the aggregate produced reuses around 0.67 tonnes of waste and captures half a tonne of CO2. The approval has also enabled Carbon8 to secure carbon credits from the United Nations, which it can sell to fund future projects. Carbon8 Aggregates chief executive David Hodgkinson said: “The development of a carbon negative aggregate with regulatory and industry acceptance is a game changer for the construction and waste industries. We believe the market wants to use our aggregate and now we can produce and sell it in large volumes. We are creating a route to market for waste and thereby significantly reducing CO2 emissions. Other countries are now expressing an interest in what we have done in the UK… The aggregated market is 1.7bn tonnes per year globally, so the potential impact is huge.” Richard Barker, director of partnership and innovation at environmental charity Waste & Resources Action Programme (WRAP) said: “We are pleased to see certification from the Environment Agency and UN, which offers confirmation of the product’s environmental credentials and contributes to the potential for its wider use. We will continue to work with Carbon8 Aggregates on accelerating the uptake of this and other resource-efficient innovations.”
