ECN-QAS -European approach for quality assurance of compost and digestate

This presentation presents the concept of the European quality assurance scheme for organic resources in respect to quality criteria for compost and digestate.

Quality assurance schemes for compost and digestion products have been established themselves in the last 20 years successfully in various European Member States as a key element for the sustainable recycling of organic residues. The market and demand for quality composts and digestate increased on account of the beneficial properties of organic fertilisers and soil improver, the need for organic matter and continuously increasing prices for mineral fertilisers. This development and also the intention by the European Commission to define an End-of-Waste standard for compost and digestate led to a demand for European uniform quality standards for composting/digestion plants and composted/anaerobic treated products. The European Compost Network ECN met this challenge and developed a concept for a European quality assurance scheme. This concept includes quality standards for recycled organic resources, especially for compost and digestate, to facilitate the free cross-border movement of goods in the EU. Based on the criteria laid down in the European standard “General criteria for certification bodies operating product certification” (EN 45011) and the experiences of existing quality assurance organisations in the field of biological waste management the ECN-QAS specifies requirements for quality assurance organisations in respect to aerobic and anaerobic treatment of bio-waste. Additional to these criteria specific requirements for the sustainable management of bio-waste with the aim to produce high quality products are given. Quality assurance leads to improve the confidence of consumer in recycled organic materials and to increase the markets for organic goods. The pre-condition for a reliable European quality assurance is to harmonise the parameter of the treatment process and the requirements for product quality and to check them regularly by an independent control. Therefore ECN has set up a comprehensive quality assurance scheme including a positive list for input materials, requirements for the treatment process and quality criteria for the end products with declaration for their specific use.

Neubau einer Trockenvergärungsanlage mit Gaseinspeisung am Standort der MVA Augsburg
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (11/2013)
Die AVA betrieb seit 1994 eine geschlossene Kompostierung, in welcher jährlich ca. 60.000 t kompostierbare Abfälle verarbeitet wurden. Da bei der Kompostierung das energetische Potenzial von Bioabfällen nicht genutzt wird, hat sich die AVA für die Errichtung einer Vergärungsanlage entschieden.

Development of local municipal solid waste management in the Western Transdanubia region of Hungary

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.

The APECS-biomass model
© Wasteconsult International (5/2015)
Organic wastes in all their different shapes and compositions have gained significant commercial, political and academic interest during the last decade. The main driver for this development is the widely accepted consideration of organic wastes as valuable resources rather than problematic or worthless stuff. With the aim to turn the economy from its fossil basis into a bio-economy with presumably higher resource efficiency and less negative or even positive climate impact, governments in many countries have startedto support the use of waste biomass in many ways including subsidies.

Post-treatment of Composting Leachate by Photocatalytic Process
© Wasteconsult International (5/2015)
In this study the capability of UV-ZnO photocatalytic process as a post Treatment method for composting leachate was examined at laboratory scale and in batch mode. The effect of some factors such as initial pH, oxidant concentration, light intensity and reaction time on the removal of organic load and color of leachate were investigated. Biological pre-treated leachate samples were collected from the effluent of leachate treatment facility of a composting plant in north of Iran. A Plexiglas column with 110 mm inner diameter and 300 mm height were used to conduct experiments. UVC lamps with different power levels in the range of 8-40W at the centre of the column were used as the source of irradiation. Based on the results of experiments, after 180 minutes of Radiation with 32W UVC lamps in pH 11 and in the presence of 1g.L-1 of slurry ZnO, maximum COD and color removal were achieved to be 57% and 67%, respectively.

Reststoffe der Papierindustrie: Ungenutzte Biomasse?
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Mit einer Altpapiereinsatzquote von 74 % (D 2013) nähert sich die Papierindustrie einer Kreislaufwirtschaft an, in der die Produkt nach der Nutzungsphase wieder Faserrohstoffe sind. Um die Produktqualitäten zu erhalten, besteht jedoch die Notwendigkeit, Fasern nach mehrfacher Nutzung aus dem Kreislauf auszusondern. Zudem müssen papierfremde Bestandteile aus dem Altpapier abgetrennt werden. Hierdurch entstehen Reststoffe. In der deutschen Papierindustrie fallen jährlich ungefähr 4,8 Mio. Tonnen an Reststoffen an. Für die Entsorgung dieser Rückstände entstehen den Papierfabriken erhebliche Kosten. Der Beitrag gibt einen Überblick über die Reststoffsituation der Papierindustrie am Beispiel Deutschland und stellt folgend zwei neue Verwertungsoptionen vor: die Rückgewinnung von Calciumcarbonat und die Herstellung von Lävulinsäure.
