Nitrogen (N) from agricultural systems contributes to the eutrophication of waterbodies through leaching. Incorporating organic material with a high carbon-to-nitrogen (C/N) ratio, such as mixed pulp mill sludges (PMSs), into the soil in autumn could

There is a great need for sustainable fertilisers and soil amendments, as current fertilisation practices negatively affect the environment. Pulp mill sludges (PMS) could provide a means to replace fertilisers made using non- renewable resources whil

Meat and bone meal (MBM) is a by-product of the meat industry and is an important pathway for recycling of N and P. MBM contains about 8% N, 5% P, 1% K and 10% Ca. Field trials compared the effects of MBM and mineral fertilizer on yield and quality o

Microbial multitudes maintain the cycles of nutritive elements in natural ecosystems. We have piloted organic residues of various processes including the food and forest industries as well as municipal waste management. This approach opens up avenues

Globally, the number of the so-called zero fibre sediments on the bottom of waterways is supposed to reach thousands of environmental deposits. These by-products of the industry are usually considered as waste causing significant ecological, health a

Väkilannoitteiden tuottaminen perustuu fossiilisen energian käyttöön. Erityisesti väkilannoitteiden sisältämän typen valmistamien vaatii runsaasti uusiutumatonta energiaa. Toisaalta väkilannoitteissa hyödynnetään myös erittäin rajallisi
