  • Composting of biological waste

    A composting plant based on new technology has been built in Savonlinna, in Finland, and came into operation at the beginning of this year. The technology was supplied by the Finnish company Vimelco Oy. The owner, Konepalvelu Suomalainen Oy, composts separately organic waste collected from the Savonlinna area, and organic waste from the food industry. In addition the nearby local authorities ...


  • Household compost as good for soil as conventional fertilisers, say EU researchers

    Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

  • Composts that contain biodegradable plastics may hinder plant growth

    Composts containing biodegradable plastics may hinder rather than help plant growth, according to a recent study by university scientists in Poland. These findings have implications for waste management practices within the EU. It is important to assess the quality and potential environmental risks associated with composts prepared from different wastes. Biodegradable plastics - known as ...

  • GEC Organics Delivers First Large Sale of Proprietary Compost Soil Amendment

  • Compacted urban soils improved with composts have long-term benefits for tree growth

    Composting to compacted urban soils can provide a lasting effect that aids tree growth, new research indicates. Urban soils improved with added organic material are less compacted after five years compared with soils that have not been treated with organic composts, the study suggests. Urban soils are often compacted from the construction and repair of buildings, roads and pavements. Compacted ...

  • Comparing N2O emissions from organic and mineral fertilisers

    A recent study compares the effects of organic, 'natural' fertilisers, such as compost, with mineral, synthetic fertilisers, such as urea, on N2O emissions from Mediterranean soil. It suggests that there is little difference between the fertilisers, but that pig slurry offers the best overall balance in terms of emissions and crop yield. Nitrous oxide (N2O) is a powerful greenhouse gas (GHG). ...

  • Target the crop not the soil - to reduce fertiliser use

    Feed the crop not the soil’ is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it. Modern agriculture is dependent on phosphorus, ...

  • SPS 2014 – Sustainable Phosphorus Summit

    SPS 2014, the fourth world summit on phosphorus and its global issues, is to be held from 1 to 3 September 2014 in Montpellier (France). Its aim is to address the issue of phosphorus, from a regional to a global scale, along with its many interactions with our societies. SPS 2014 will be held just after PSP5 - Phosphorus in Soil and Plants, ...
