プロジェクト概要

The Avonmouth project is part of a portfolio of carbon capture and utilization facilities using Accelerated Carbonation Technology (ACT) to convert industrial CO₂ emissions into solid building materials. The project captures CO₂ and reacts it with alkali earth hydroxides and silicates in waste materials, resulting in carbonated aggregate suitable for use in construction.
The production process involves blending thermal residues, conditioning them with water, and exposing them to concentrated CO₂. This produces aggregate with a verified carbon content of 144 kg of CO₂ per tonne of product. In the full calendar year prior to project registration, the facility produced 401,773 tonnes of carbonated aggregate, illustrating its scale and carbon removal potential.
The project complies with the Puro Standard General Rules and Carbonated Building Material Methodology, supported by permitting, verification, and regular compliance checks. It is also part of a larger expansion plan, with a new facility under development in Wretham and international plants underway in Australia, Japan, and Spain.
