WRAP’s AD project manager David Tozer outlined some of the “near to market” solutions that the organisation is taking forward under its ‘Driving Innovation in AD’ (DIAD) programme in terms of assessing feasibility.

Processes being trialled at demonstration level include enriching digesters with different CO2 inputs to increase biogas potential, upgrading biogas to vehicle fuel, and utilising a wider range of feedstocks at small-scale level.

Much of the work the DIAD scheme seeks to encourage is around transferring technology expertise from other sectors such as the water industry, driving greater efficiencies and simplifying operational costs.

“We are looking to optimise AD at all scales – we want technologies that really stand out from the crowd,” Tozer said.

Tozer said the next step was to promote such innovations to the wider waste industry to obtain feedback and input. He was speaking at EFW Expo at Sustainability Live in Birmingham earlier today.
