Back to clients Crapper & Sons Long-standing waste management firm Crapper & Sons has further strengthened its resource agenda, having invested in a new shredding system to transform wood waste into a biomass fuel. Having started out as a quarrying firm more than 60 years ago, Crapper & Sons owns a landfill site in Wiltshire, but 30 acres is actually dedicated to salvaging as much ‘waste’ as possible. The family-run business was previously processing wood at its Wootton Bassett headquarters, using one high speed shredder fed by one slow speed shredder. But limited resistance to foreign objects within the waste stream, was resulting in unmanageable machine breakdowns and operational downtime. The search for an alternative shredding system therefore began and research brought the team to UNTHA.
