Over the years we have posted about secondary aggregates and recycled aggregates, both of which represent more sustainable alternatives to primary or virgin aggregates.
Here's another example, this time from a Lanarkshire company that has recently launched a new range of low-carbon aggregate produced from incinerator bottom ash, together with recycled sand produced from street sweepings and gully waste:

Levenseat’s low carbon product offering is designed to help construction firms lower their building costs while also reducing their environmental impact by replacing virgin aggregate within concrete – for each tonne of recycled aggregate used, 29kg CO2 is saved from being emitted. In 2020 2.7 million tonnes of IBA was produced from Energy from Waste plants in the UK.
Earlier this year, we posted about carbon-negative aggregates. This has now helped Jackson Civil Engineering secure an Environment Agency Flood & Coast 2021 Excellence Award.
O.C.O’s aggregates sales and development manager said:
Not only have we been able to show that carbon-negative aggregates have a role to play in sustainable construction and the road to carbon zero, but also, just as importantly, that they offer a credible alternative to using up our finite resources of traditional sand and gravel.
I really feel the tide is beginning to change; people will have to start looking for alternatives and I think this award will open their eyes to the fact there is a manufactured product that can be used in various applications – such as asphalt and Type 1 concrete – which is both proven to work and is environmentally friendly.
