phosphorus methods for improving bioavailability of wastewater P Ministry Ylivainio from capture products, creating a new fertilizer end product. of sewage The second aim is to develop a common method for sludge to estimating bioavailability of P for efficient and fertilizer environmentally friendly use of the capture products. World’s mineral phosphorus (P) reserves are diminishing, leading to elevated prices of P fertilizers. For sustainable agriculture practices, new ways of recycling P and closing the circulation are needed. In Finland, P in sewage sludge is the most neglected P source in agricultural production due to, among other things, low bio‐availability of P in the capture products. Rec Alkaline Rec Alkaline Ltd is developing a method for recycling ? ? Jarmo Pudas Alkaline battery alkaline batteries, which will raise the recovery rate above 80 percent. The method for chemical processing of funding recycling alkaline batteries takes place at room temperature so it consumes a fraction of the energy required by the foundry method. Investment costs are also significantly lower than with smelter technology, which requires substantial initial spending. And the recovery rate is almost twice as good as smelters can offer. The company has studied and developed the process for many years. Financing from Tekes facilitated the initial research and helped to chart chemical models. The company has started building the technology in 2015. The factory will be completed during Q3/2017. SAVE Agricultural Gypsum, mainly consisting of calcium sulphate with some 2016 ?

At Yara’s Siilinjärvi plant, Finland, some 1.3 million tons of gypsum is produced yearly.
