Back to clients Advetec Bath-headquartered Advetec has treated a variety of waste and effluent, since it was established in 2000. But keen to develop a more homogenous product for optimal digestion rates, the business reached out to UNTHA… Engineering company Advetec is no stranger to the scientific bio-degradation of waste. But a partnership with UNTHA UK means the team has been able to roll out a sophisticated aerobic digestion solution for a selection of mixed waste streams. Municipal waste shredding trials first led Advetec to invest in two UNTHA RS30s, which were shipped to the Caribbean and USA to process materials down to a defined <50mm specification.
