Effects of compost and digestate on environment and plant production - results of two research projects

Composts and digestates can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the products and on their utilization.

Composting and digestion of biogenic waste materials and subsequent application of compost and digestate to the soil contribute to the recycling of nutrients and to the production of renewable energy. Moreover, compost and digestion residues (digestate) can improve soil fertility and suppress plant diseases. On the other hand, compost and digestate may also contain a variety of pollutants such as heavy metals and organic contaminants, which are hazardous for the soil.
Compost and digestate have been thoroughly investigated within two associated projects entitled.
- Organic pollutants in compost and digestate in Switzerland
- Effects of composts and digestate on the environment, soil fertility and plant health
These projects yielded new insights into the properties of compost and Digestate, mainly with regard to biological parameters and the occurrence of both "classic" and "emerging" organic pollutants.
The presentation will summarize the results of these two very large and valuable research projects for organic waste recycling.

Mechanical Biological Treatment (MBT) in the UK - A personal view -
© Arbeitsgemeinschaft Stoffspezifische Abfallbehandlung ASA e.V. (9/2012)
I should first point out that I am presenting as an individual not on behalf of my current employer. That is why my slides are branded “Happy Algernon” -this is the company that kindly put the presentation pack together for me. The presentation will explore:- The background of the three major project areas I have worked in that have helped shape my thoughts on MBT. Some of the relevant statistics for the UK and the definition of MBT (for the purposes of this presentation). The reasons why I believe MBT has emerged as being a lead technology for the treatment of MSW. What the future is likely to hold for MBT. The first two areas I worked in were Hampshire and West Sussex which are both Counties on the South Coast of England.

Seit 2003 ist die Eisenmann Anlagenbau GmbH & Co. KG auf dem Markt für Biogasanlagen aktiv und hat bis jetzt etwa 90 Biogasanlagen mit horizontalem Hauptfermenter verkauft. Stand zu Beginn der Bau von landwirtschaftlichen Biogasanlagen im Vordergrund, ist dem Unternehmen inzwischen auch der Einstieg in den Bioabfallsektor gelungen. So hat Eisenmann während der letzten drei Jahre die Unternehmensaktivitäten erfolgreich um Bioabfall-Vergärungsanlagen erweitert werden.

Durch den Erwerb der Schmack Biogas GmbH zu Beginn 2010 konnte der Bereich Biogas innerhalb der Viessmann Group weiter ausgebaut werden. Neben der Firma BIOFerm im Bereich der Trockenvergärung konnten dadurch zusätzliche Kompetenzen im Bereich der Nassvergärung sowie Gasaufbereitung (CARBOTECH GmbH, ebenfalls Viessmann Group) aufgebaut werden. Somit ist man der einzige Komplettanbieter am Biogasmarkt, da durch die Firma ESS auch Blockheizkraftwerke aus dem Hause Viessmann stammen. Durch die Zusammenführung der beiden Kompetenzmarken BIOFerm und Schmack Biogas am Standort Schwandorf ergeben sich vielseitige Vorteile, vor allem für die BIOFerm GmbH.

Current compost production in Izmir and the utilization of the residues from composting process

Landfilling is the main disposal method to remove organic solid waste in Turkey. Even if the domestic solid waste generally has high water content and it is reach by means of biodegradables, the number of composting facilities is limited and they are mainly located in the cities with high population. However, composting is an advantageous method for the countries having both high amounts of organics in their waste and widespread agricultural activities, such as Turkey. Limited landfilling areas and difficulties to locate new landfills are the effects to aim composting, as well as it is the priority disposal method of Turkish Ministry of Environment and Forestry.

The waste disposal system in Poland is one of the least advanced in Europe. Despite great efforts over the last 20 years municipal waste landfilling has only reduced from 95 percent in 1991 to 73 percent in 2010. This still means that millions of tonnes of post-consumer waste continue to be landfilled.
