Ash blocks reduce landfill

MATERIALS Cutting Edge

GOVERNMENT efforts to reduce the amount of waste buried in landfill sites has seen an increase in costs associated with dumping rubbish.

Many local authorities are turning to burning municipal waste in incinerators but even this leaves some waste ash that has to be sent off to expensive landfill sites.

But now a West Bromwich-based company has hit upon an idea to use the left over ash found in incinerators and turn it into useful building products.

ATRR uses the incinerator bottom ash to replace some of the aggregates normally used in concrete production to manufacture concrete blocks, ready mixed concrete and foamed concrete. It started producing foamed concrete last October and blocks and ready mixed concrete at the start of the year.Already the products have had some success on local schemes.

Group commercial manager Rod Stanley said: 'We have seen a marked increase in demand since the Government introduced the new landfill limits and demand for the concrete blocks is also starting to increase.'
