The object of sludge characterization must be to get quantitative mea- sures for sludge behaviour in treatment processes and when disposed of. Thus the incentive for characterization could be one of the following: 1. Because sludges exist in large quantities we want to know the amounts and the expenees involved in their treatment and disposal. 2. Because sludges are environmental nuicances/hazards, energy sourc:-es, fertilizers or even food sources; we want to know their potential. 3. Because the processes change the sludge propert~es, we w~nt to know their "treatability". 4. 5ecause sludges...

Disposal of organic sludge and liquid agricultural wastes is a universal problem. Their production cannot be halted and as steps are taken to maintain or improve the quality of rivers and lakes it grows in quanti ty. The Commission's early awareness of the need for action to prepare for substantial growth in the Community's' sludge disposal problem led to the setting up of the COST 68 project to coordinate and guide European research and development work with particular emphasis on recycling sludge to agricultural land. Two years ago the field of research activi ties was extended to liquid...

The agricultural value of sewage sludges is well known and a lot of published data has demonstrated the positive effects of sludge appli- cations on plant growth and yield. These effects are probably due mainly to the nitrogen and phosphorus content of sewage sludges. But, as sludges are more organic than mineral, we can expect an effect of the organic matter added to the soil on soil fertility. Certainly, in the future, landspreading of sludges will be regulated, taking into account pollution hazards for waters (excess of nitrogen and phosphorus supply compared to plant needs and soil...
