Prosper De Mulder Group (PDM) is spearheading a multi-million pound project to roll out anaerobic digestion plants turning food waste into biogas across the UK.
The first such plant will be built at PDM’s Doncaster headquarters. “If successful, we will build another four in Widnes, Exeter, Hartshill in Nuneaton, and Silvertown in London,” said PDM engineering manager Robert Smith. All gas produced will be fed back into the national grid.
The cost of building the initial Doncaster plant alone is estimated to be £12M and Smith said he hoped building would begin for this in the New Year, having secured planning permission.
The plant would take about a year to construct, he added. “We have to be producing by this time next year.” The facility would generate 2MW of energy annually. It would yield return on investment in less than three years, predicted Smith. It would be handling waste from all parts of the supply chain, such as supermarkets, restaurants and processors and would be able to process 1,000t per week.
PDM handles 1Mt of animal by-product annually from a range of abattoirs, butchers’ shops, food manufacturers and supermarkets, transforming it into products such as petfood ingredients, proteins and liquid fats. The company already uses food waste to generate renewable electricity through biomass Combined Heat & Power units.
