| Popis: | International audience; In France, and in Europe, the main manure management practice is still storage followed by manure spreading. In regions with intensive livestock farming and high manure production, treatment of manure may be essential to reduce losses of nutrients into water resources as well as to reduce gas emissions. In France, manure is treated for commercial reasons or in some regions, as a solution, mandatory or not, to limit the nitrogen (N) and phosphorus (P) surplus. Aerobic treatment of slurry was developed in Brittany (northwest France) to reduce N flow into aquatic environments, while anaerobic treatment was introduced more recently to promote general N management and mitigate climate change. French data on the use of manure treatment are still sporadic, dispersed and not always synthesized except when government or professional organizations publish the data. The objective of this study was thus to collect all available data on the treatment of manure from cattle, pig and poultry farms for an overview of manure treatment in France. Specific surveys in 2008 showed that 12% of pig farms, 11% of poultry farms and 7.5% of cattle farms was concerned by manure treatment. For cattle farms, only questions concerning composting were asked. Responses from poultry farms showed that manure was treated mainly by composting (53.7% of farms that treated their manure), followed by drying (15.1% of farms that treated their manure), separation (2.3% farms that treated their manure). A total of 13.6% of poultry farmers who treated manure said they used another treatment but without specifying which. Treatment on pig farms accounted for 4.2 million m3 of slurry and the main type of treatment was aerobic (2.9 million m3) in large units. Physical-chemical treatment concerned 10.7% of the total volume of manure treated and 16.4% of farms that treated their manure. Composting of pig slurry with straw accounted for 5% of the volume of manure treated and lagoons for 3%. Taken together, the treatment of pig, poultry and cattle manure accounted for 12.7 million tons corresponding to 10.6% of the total annual tonnage (120 million tons). The main processes, mostly applied on the farm, were composting (8.5 million tons), aerobic treatment (2.9 million of m3 of pig slurry) and anaerobic digestion (1 million tons). Other manure treatments, including physical-chemical treatment, were less frequent (0.4 million of m3). Treated manure was mainly used to fertilize the soil and crops on the farm concerned. Manure treatment can thus be considered to be underused in France. One constraint to the expansion of anaerobic digestion is that agricultural use of the digestate requires registration or normalization to become an amendment or an organic fertilizer. Anaerobic digestion is expected expand to reach the European target of 20% of energy from renewable sources. Nevertheless, this expansion will depend on overcoming the constraint requiring registration or normalization of the use of the digestate as fertilizer. Thus, to avoid penalizing farmers, the further development or creation of collective processing platforms (composting, drying, etc.) is recommended, combined with a N recovery process that will enable the production of organic amendments and fertilizers in an easy marketable form. |
