- Industrial Compostability After many years of development and intensive discussions in normalization committees, requirements for industrial compostability have become well established and have been firmly fixed in several norms. In all of the above norms, the same 4 essential requirements are specified: Biodegradation shows quantitatively the inherent characteristic of the material to be consumed by microorganisms and […]
- Home Compostability While the first norms on industrial compostability were already published at the turn of the century, it took 10 more years to create a norm on home compostability. Based on AS 4736, the Australian norm on industrial compostability, Australian Standards published in 2010 world’s first norm on home compostability: AS 5810. Nevertheless, several other certification […]
- Degradation in other environments In case the product’s intended disposal route does not include industrial or home composting, other conditions need to be selected, representative for the environment in which the product will need to degrade after being disposed of. In this context, different environments can be selected, including soil, fresh water, marine water, anaerobic digestion or landfill. OWS […]

- Feasability – Input material To assure that the input substrates will have no adverse effect on the process, several parameters need to be analyzed, providing a first impression of the suitability of a product for anaerobic digestion. Selection test In case the waste contains impurities (e.g. municipal solid waste), a thorough pre-treatment will be necessary. A selection test will […]
- Life Cycle Assessment The life cycle analysis studies the entire product chain, from cradle to grave, and provides valuable insights into the environmental sustainability of activities. Life cycle assessment has been identified by the European Commission as the most valuable framework to assess the environmental impact of activities. OWS serves as an independent and experienced partner to perform […]
- Feasability – Anaerobic digestion process When little information is known on the suitability of the substrates for anaerobic digestion, 2 important tests are available to evaluate if a substrate or a mixture of substrates can sustain stable fermentation. Biogas Production Potential (BPP) test Determines the maximum amount of biogas that can be produced from a given feedstock. The feedstock is […]
- Feasability – Digestate The output after anaerobic digestion (as such or after post-treatment) can have many applications (direct use as fertilizer, compost after post-treatment, cover in landfilling,…). To evaluate what application offers the best options, it is important to analyse several parameters on the output. The selection of the necessary parameters happens in consultation with the client and […]
- BES-CSTR process OWS offers the design and construction of wet completely mixed digesters. These digesters work at a low total solids-content and can be used as main digesters, or as post-digesters (e.g. following a DRANCO-FARM or BES-Plugflow digester). Technology OWS uses this type of technology for clean and wet […]
- SORDISEP process Wet separation technology for maximum recycling and high quality compost of MSW The wet separation process is positioned after the DRANCO digester in order to treat a digestate free from sticky organic components which are converted into biogas in the digester, facilitating wet separation and optimal removal of inerts and sand. Inerts, sand and organic […]
