BioCover www.biocover.dk Photo: slurry tanker equipped with SyreN InterReg project has been launched to roll-out manure slurry acidification in the Baltic States, following on from Denmark’s experience (see SyreN above). The objective is to reduce ammonia emissions to air during slurry application, in order to cut greenhouse gas impacts to eutrophication (atmospheric deposition of N to the Baltic), as well as avoiding loss of valuable nitrogen nutrient for farmers. Over 1 000 famers are already using one or more modules of SyreN technology for acidification during slurry spreading (see above). The InterReg project aims to enhance capacity of public authorities and farmers, through pilot installations, feasibility studies and environmental and economic assessments.
International seminar on slurry acidification to reduce ammonia emissions, 28 - 29 September 2016, Vejle, Denmark (nearby Billund Airport) www.conferencemanager.dk/acidification KOTO company’s AlgaeBioGas installation, Llubljana, Slovenia, is featured as one of the European Biogas Association (EBA)’s six Success Stories: anaerobic digestion of biodegradeable municipal solid waste in European cities. The 13 000 m3/y feedstock anaerobic digesters, using mainly household food waste and food industry wastes, produce methane used for co-generation (4 GWh/y electricity and 2.8 GWh/y thermal energy). Part of the resulting digestate (0.5 m3/day) is used to feed a pilot-scale open raceway algae pond (30 m2), commissioned in 2014, ensuring biological treatment of the digestate and recycling nutrients into production of algae, which are then used as feedstock for further methane production, or for use in bioplastics or fertiliser production. The system is energy and greenhouse emission efficient, because exhaust gas from the methane-burning electricity co-generation is injected into the algae production pond, so using the waste heat and carbon dioxide in algae production, as well as reducing digestate odor. /www.algaebiogas.eu/
Projects PHOSave project (Horizon 2020 SME Instrument), led by PROPHOS Chemicals will construct a pilot plant near Cromona, Lombardy, to recover and recycle phosphates from exhausted fire extinguishing powders. Halogenated chemicals in fire extinguishers have been largely replaced by phosphate based dry powders, because phosphate does not pose environmental or health issues and is effective in combating fire. Prophos Chemicals is Italy’s only producer of dry fire extinguisher chemicals of all classes. Fire extinguishers have to be periodically emptied, overhauled, refilled and re-pressurised, to guarantee reliable performance in case of fire. The recovered phosphate will be recycled into the chemical industry or as fertilisers. BioEconomy pilot project “Biogas beyond energy” (European Commission, Regional and Urban Policy). The project also involves Brandenburg (Germany), Baden-Württenberg (Germany), North-Rhein Westfalia (Germany), Navarra (Spain), Asturias (Spain), Skåne (Sweden), Emilia Romagna (Italy), Malopolska (Poland), and West Finland. The product will develop valorisation of different sources of organic raw materials as biogas plant inputs, in particular livestock manure, and transformation into value-added products including fuels, chemicals, energy and recycled nutrients.

The authors estimated that improved management of P in China (better use, recycling) could prolong the lifetime of China’s phosphate rock reserves by 20 years.
“Intensification of phosphorus cycling in China since the 1600s”, X. Liu, H. Sheng, S. Jiang, Z. Yuan, C. Zhang, J. Elser, PNAS (Proceedings of the National Academy of Sciences of the USA), vol. 113, n° 10, 2016 , reduce losses to water bodies by nearly 30% and nearly avoid consumption of mineral P fertilisers. This optimal scenario includes recycling, reduction of meat consumption, improved crop P-efficiency, optimisation in other applications (gardens, industry), reduction of point source emissions and soil erosion.

50% P-recovery from Germany’s sewage biosolids is feasibleScenarios are proposed to recover 50% of total phosphorus in Germany’s sewage sludge biosolids. Economic and environmental impacts are assessed. Of c. 60 000 tP/year in German sewage sludge, around 25-30% are currently used in agriculture and this should remain an important part of nutrient recycling for high-quality biosolids. To efficiently recover P from the remaining sludge will require modification of logistics in sludge treatment, to ensure that sewage sludge goes to mono-incineration and is not mixed with low phosphorus wastes, in order to deliver sewage sludge incineration ash with a P content of around 8%. Technical processes are available to recover P from such ash. A scenario with 30% recovery of Germany’s sewage biosolids P by technical processes from ash, and 20% continuing to be used in agriculture, resulting in a net positive impact for energy consumption and climate change emissions. “Phosphorrecycling aus Klärschlamm in Deutschland: eine Abschätzung von Kosten und Umweltauswirkungen” (Phosphorus recycling from sewage sludge in Germany : an estimate of costs and environmental impacts), F.
