Waste Management

Carbfix and Waste Management

Carbfix and Sorpa, the waste management centre in Reykjavík, will start capturing and storing CO2 from the landfill site in Álfsnes, near Reykjavík. CO2 is sourced from organic waste forming as a byproduct along with methane, which is sold on the domestic market. The CO2 will be captured in a water scrubbing unit at the waste management facilities of Sorpa and injected for permanent mineral storage underground. The pilot phase in 2022 will store 3,500 tonnes of CO2 and build up to 7,500 tonnes. This project aims to reduce the carbon footprint associated with domestic waste disposal. Additionally, the feasibility of issuing certified carbon credits based on the project will be assessed.

The project is a multi-disciplinary collaboration between Carbfix, SORPAiCert, and GeoEnergy with support of Global Environmental Markets. This project is funded by the Development fund of Rannís – The Icelandic Centre for Research.

Carbfix in older rocks for the first time

The project will, for the first time, demonstrate the Carbfix technology in older and less permeable rocks than previously considered. In addition, it represents a new industrial source of CO2 that is not geothermally derived nor sourced from Direct Air Capture (DAC). The successful implementation of the technology in these rocks and from waste management will have important implications for the application of the Carbfix technology worldwide.

Carbon credits

As part of this project, a standard and technical framework for climate mitigation solutions will be developed. The goal is to make certified and verified carbon credits commercially available on international carbon markets. A technological solution, in adherence to the standard, will be developed to capture CO2 emitted from organic waste at the facilities of Sorpa in Álfsnes and inject it for permanent mineralisation underground via the Carbfix method. The project will reduce the emission of greenhouse gases by thousands of tonnes per year and form the basis of a carbon offset program that is both permanent and measurable in real time.
