The European community cannot address the issue of bio-waste solely in terms of collection and waste management, assuch activities generate costs. Today, waste prevention in Europe must involve waste reduction and prevention at a locallevel, targeting all producers of bio-waste, not only consumers and households, and promoting the use of a number ofwaste reduction practices including composting, mulching, grinding, use of slow-growing plant species, using bio-wasteas animal feed, reducing food wastage and the use of ramial wood chips.

The Miniwaste project, supported by the European Life+ program (2010-2012), aims to provide evidence that it ispossible to significantly reduce the production of bio-waste generated in the European Union, as well as provide toolsand points of further reflection on bio-waste prevention.The partnership (Rennes Métropole, Irstea, City of Brno, LIPOR in Porto, and ACR+) wishes to set up a computerisedtool for local authorities within Europe. This project will help users to conduct a bio-waste management programmeincluding territorial diagnosis, the implementation and monitoring of specific preventive actions and the evaluation ofthese actions.The overall structure will be based on three different modules:1-A decision making assistance module that includes a territorial diagnosis chart offering several scenarios associatedwith different potential possible actions in the field of bio-waste prevention:Composting (home, community, apartment blocks, vermi-composting, catering services), food waste (household,restaurant), smart gardening and animal feeding.The territorial diagnosis is produced on the scale chosen by the user in order to get homogeneous data. It could be aneighbourhood, district, town, etc.For a given sector, the decision making module consists in entering data of 15 territorial indicators in terms ofpopulation, current waste management and current preventive actions on the territory, etc. Meanwhile, a calculation ofpotential waste reduction is processed by the computer using an algorithm.The result of the diagnosis is displayed for the whole territory and for each sector according to the list defined.Corresponding to the results, synthetic worksheets are proposed as a real decision making tool with the followinginformation: target, type of waste concerned, linked indicators, main actions, participants involved, materials necessary,personnel necessary, an estimate of cost, and expected results.With such information (diagnosis and worksheets), the users are able to choose one or several preventive actions toimplement in their territory.2-Some guidelines to implement the actions and especially some data sheets proposing activity indicators and impactindicators: depending on the preventive actions chosen, the user can download the corresponding procedural sheetwhich explains step by step how to implement the actions in detail. Moreover, a data sheet is available with a list ofrelevant indicators (awareness, number of composters, etc.)3-A results display module, producing graphs to help visualise the results.This web tool will be available on the Miniwaste website by subscription, from 2013 (www.miniwaste.eu). Moreinformation will be provided and a tool demonstration will be organized during the final conference scheduled in Rennes in November 2012.

Umweltbildung mit #wirfuerbio
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (4/2023)
#wirfuerbio ist die bundesweite Kampagne der kommunalen Abfallwirtschaft zur Reduzierung von Störstoffen im Bioabfall. Mit einer starken Bandbreite unterschiedlicher crossmedialer Kommunikationsmittel und Maßnahmen verändert sich das Verhalten der Biotonnenbenutzer. Die Störstoffquote sinkt um mehr als 50 Prozent. Die Kampagne weist einen neuen Weg in der Umweltbildung. Mit der Abfallbox und der SpieleApp „#wirfuerbio das Sortierspiel“ wird Kreislaufwirtschaft in Form von Spaß und Spiel erlebbar. Der Beitrag zeigt, wie Abfallbox und Spiele-App didaktisch funktionieren und ein Bewusstsein für Kreislaufwirtschaft und Mülltrennung entwickeln.
Feldversuche zum Abbauverhalten von kompostierbaren Vorsammelhilfen in der technischen Kompostierung
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (4/2023)
Kompostierbare Vorsammelhilfen (zertifiziert nach EN 13432 und „OK Compost Home“) wurden zwei Versuchsmieten in „realitätsnahen“ Mengen zugesetzt, wobei eine theoretische Befüllung von 1 bis 1,2 kg Bioabfall pro Vorsammelhilfe erreicht wurde. Die Vorsammelhilfen fragmentierten bereits in den ersten beiden Rottewochen und verschwanden zwischen der zweiten und der vierten Woche in der Fraktion > 10 mm vollständig. Geringe Partikelanzahlen vom Typ der untersuchten Vorsammelhilfen konnten in der Fraktion 0,63 bis 0,2 mm in der Anlage 1 nach neun Wochen und in Anlage 2 nach zwölf Wochen nachgewiesen werden, wodurch gezeigt werden konnte, dass die untersuchten Vorsammelhilfen während der ordnungsgemäßen Kompostierung kaum zu Mikrokunststoffen fragmentiert.
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.
Digestate and compost quality - case studies at anaerobic disgestion plants with the BTA Process
© European Compost Network ECN e.V. (6/2012)
The key for the successful anaerobic digestion of biowaste and/or municipal solid waste is an efficient removal of the impurities before the digestion step. This is not only indispensable for the reliability of the process and therefore the plant availability, but furthermore for the quality of the produced digestate or final compost. With the existing
developments within the EU, the quality of the digestate / compost has become a focus of attention.

Organic waste composts as potential fertilisers for cereal prodktion in developing merket
© European Compost Network ECN e.V. (6/2012)
Production of waste compost is well established in many European countries. In developing markets, however, the waste composts are not fully accepted as conventional organic fertilisers. The nutrient value of composts must be studied locally. The aim of the study was to investigate the potential fertilisation value of two composts for cereal production.
