Pre-treatment solutions from ADBA members


The compact, patented separation hammer mill from Swiss company Hybag Automationen AG is the preferred solution for food waste pre-treatment for Metamo Process Engineering Ltd. The Hybag equipment transforms off-spec produce, crop waste, leftovers and wrapped or packaged food waste into an easy to pump, organic substrate in one simple, low energy, low water process. The resulting soup-like substrate is at least 99 per cent organic, with around 15 per cent dry matter and an average particle size of 3-4mm, increasing the gas yield from digestion. Packaging, plastics, cutlery and other extraneous materials are ejected almost dry and at least 99 per cent free from organic matter without further treatment, leaving them suitable for recycling – saving landfill or incineration costs. In combination with Hybag’s tipping trough, conveyor and pump system, the separation hammer mill creates a highly efficient process unit for the pre-treatment of food waste, with several machines already installed for UK waste management companies.


Following extensive testing and years of product development with several leading waste


companies, MSE Hiller has unveiled its new Smicon SMIMO120 depackaging machine. Offering high capacity up to 25 t/hr and superior performance, the Smicon delivers a clean, organic substrate ideal for anaerobic digestion, as well as cleaner packaging waste, meaning lower disposal costs. The unit’s lower


operating speeds of around 500 rpm deliver an increased equipment lifespan, reduced maintenance and running costs, lower energy consumption, and reduced noise levels. The company also offers a test and demonstration truck for use at clients’ sites.


In July 2015, Weltec Biopower will commission a 500 kW AD plant in Northern Ireland, for vegetable producer Gilfresh Produce. With a mixed feedstock comprising vegetable waste, cattle manure and chicken litter, as well as whole crop,
