Promoting the benefits of carbon negative aggregates
Technology’s David Olley, Aggregates Sales and Development Manager, and James
Ng, APCr Contracts Manager, will be talking about the benefits of carbon
negative aggregates at next week’s New Horizons – Building the Recovery online
by the QMJ Group, which also runs Quarry Management magazine, the Agg-Net
portal and the Hillhead exhibition, the event is designed to give delegates a
better understanding of the climate-related issues and challenges facing the
industry, while also looking the latest innovations to help achieve a
O.C.O team will be presenting on Tuesday (30 March) during the Decarbonization
stream of the conference. Their session begins at 10.15am, with a video
presentation followed by a Q&A session hosted by broadcaster Susannah
said: “This is the perfect opportunity to explain the science behind carbon
capture, the work that goes into producing our carbon negative Manufactured
Limestone (M-LS) and the benefits of using sustainable construction materials.
the drive towards improving green credentials within the building sector
gathers pace, it is really important that products like these become the
specifiers’ preferred choice. This aggregate works the same way as virgin
materials, it is fully certified and accredited and, above all, it provides
permanent carbon capture while also reducing the need to quarry more natural
2020, O.C.O produced over 310,000 tonnes of carbon negative aggregate from its
three UK operations in Leeds, Avonmouth and Suffolk, and that figure is
expected to grow considerably as the aggregate gains a stronger foothold within
the construction sector.
was the first company to commercialise the manufacture of carbon negative
aggregate on a commercial scale, using its Accelerated Carbonation Technology
(ACT) process to treat Air Pollution Control residues (APCr) from the Energy
from Waste (EfW) sector with waste
carbon dioxide gas, to enable the permanent
capture of significant amounts of CO2.
In 2011, the UK’s Environment Agency granted the product End of Waste (EoW) approval. It was the first time any company in Europe had achieved such an accolade for an APCr waste stream and secured the aggregate’s position as a perfect example of the circular economy in action.
