International congress - Compost and digestate: sustainability, benefits, impacts for the environment and for plant production



The CODIS 2008 has taken place on February 27th – 29th 2008 in Solothurn, Switzerland.

Welcome to CODIS 2008

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 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" and "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 CODIS 2008 congress is the final event of these two projects.

  • Project description "Effects of Composts and Digestate on the Environment, Soil Fertility and Plant Health"

CODIS 2008 is a platform where scientists, practitioners and authorities meet to discuss current issues and future trends.

Concept of CODIS 2008

The main focus of CODIS 2008 will be on the quality of compost and digestate derived from source separated biogenic waste and animal manure. Beneficial and adverse impacts on the environment and plant production due to the application of compost and digestate and the production of renewable energy will be considered.

CODIS 2008 is organized in two parts: In the first two days, the scientific community will have the opportunity to present and discuss their results. These two days comprise plenary sessions, parallel sessions and poster sessions. These two days will be held in English.

The third day is devoted to an encounter between the scientific community, practitioners and representatives of public authorities. It is possible for these people to participate only in the third day, during which presentations will be translated simultaneously into German.
