Serving abattoirs, butchers' shops, food manufacturers and supermarkets, PDM processes over one million tonnes of animal by-products each year.

With five rendering plants located across the country, PDM is the only company able to handle all different categories (1, 2 and 3) of ABP and process into a range of different products, be it as diverse as energy or pet food ingredients.

PDM's nationwide collection service means it covers every high street in the UK and already visits over 10,000 individual customer sites each week.

With a strong focus on research and development, PDM's plants have benefited from continuous investment in new technology and environmental control systems to ensure that product quality, safety and emissions standards are consistently second-to-none and comply with all relevant legislation and operating permits.
