BIODEGMA® Box Systems with GORE® laminate and GORE®HEAP Cover are officially Best Available Techniques for the Biological Treatment of biodegradable Waste in the European Union

In October 2017 the European IPPC Bureau has released the so called “Final Draft” of the BREF Document (Best Available Technique Reference Document) for Waste Treatment. The BREF Documents are key pieces of the European Industrial Emissions Directive (IED DIRECTIVE 2010/75/EU) which aims at preventing or where this is not possible reducing pollution to protect the environment. It describes identified Best Available Techniques (BATs) to achieve such goals for certain industrial activities like inter alia biological waste treatment operations.

During a 3,5 year revision process of the former Waste Treatment BREF from August 2006 different expert subgroups, have compiled and described techniques representing the most effective and advanced stage which achieve high general levels of environmental protection while allowing broad implementation in the Member States due to their technical and economic viability.

The ECN TG BREF as the responsible subgroup for Biological Waste Treatment had been mandated to as well work out BATs for aerobic treatment operations like inter alia composting.

While the common theme concerning the best available technique status of emission abatement measures for aerobic waste treatment operations besides of good daily practice purely circled around end-of-pipe means like e.g. biofilters and scrubbers the experts had to as well consider and acknowledge the many well working installations of the technique “Semipermeable membrane covers with forced positive aeration” particularly with GORE® Cover®- and GORE® Box laminates all over Europe and globally for various biological treatment operations, like composting, stabilization and biodrying.

Subchapter 4.5.2.3 of the Waste Treatment BREF describes before mentioned technique in detail particularly its abatement performance treating emissions, such as odours, ammonia, VOCs, dust and bioaerosols.

The initial criticism of such a point of source emission abatement (treatment installations like e.g. GORE® Cover-or Biodegma Box installations work as two in one systems in which the biological reactor acts as well as emission control means due to the encapsulation with GORE´s semipermeable membrane laminates) could be overcome by a broad range of emission control data which provide evidence of the equivalence to end of pipe means like biofilters.

Nevertheless, due to low energy consumption, smaller footprints as well as lower OPEX and CAPEX like e.g. enclosed buildings this technique provides an optimum ratio of high environmental protection and economic viability.
