Hanson UK makes 85 per cent cut in waste to landfill since 2010

Hanson UK, a leading building materials supplier, has gone beyond its 2020 target of reducing the amount of non-process waste from its operations sent to landfill by 85 per cent since 2010, according to its latest sustainability report.

The report, released on 8 June, lists a number of examples of sustainability progress made by Hanson UK since 2010, with significant gains made in waste and resource use. The report reveals that in 2017, only 0.06 kilogrammes (kg) of every tonne of product it produced went to landfill, down from 0.54kg in 2010 – a decrease of 89 per cent that Hanson attributes to new reuse and recycling initiatives targeting cement, concrete and asphalt produced by the company.

Targets remain for waste and resource use, with Hanson aiming to increase cement replacements in concrete to 45 per cent, as well as recycled aggregate in asphalt to 10 per cent – the amount of recycled asphalt planings used in new asphalt has also increased by 14 per cent since last year – and to have concrete plants recycling 95 per cent of surplus concrete.

Waste reduction is also a key focus of the company’s sustainability plans, with Hanson aiming to reduce by-products from the production of aggregates like fine materials and dust. Where they are produced, they are reprocessed and sent off to be used as artificial sand.

In terms of resource use, Hanson has also registered significant decreases in its water use, achieving a 32 per cent reduction in mains water use since 2010, beating the 2020 target of 25 per cent.

Carbon emissions were also in the crosshairs for the company, with carbon emissions per tonne of product falling by more than 14 per cent since 2010, although CO2 emissions per tonne from transport rose by one per cent in 2017.
