Unsustainable global phosphorus (P) management has led to target digestate from anaerobic digestion (AD) as a potential source for P recovery. However, although modeling interactions within AD is crucial recovery optimization, model inputs often require accurate fractioning into different minerals, e.g., struvite, vivianite, amorphous calcium phosphate (ACP). This study aims develop new method based on acidic leachate of P, Ca, Mg, Fe, K, and Al. We acidified 9 samples, 3 being digestate, the other 6 are substrates used biogas unit feeding. Main results obtained acidification curves each nutrient in sample. Nutrient allowed us construct algorithm P. Finally, elemental was achieved all samples. Acidification protocol its then proposed environmental samples implicated AD.

Cow manure (CM) is one of the largest secondary sources phosphorus, while mined phosphorus rock becoming scarce and diminishing in quality. Phosphorus recovery from CM essential for increasing use efficiency and, therefore, securing future food production. Calcium phosphate (CaP) granulation can enable efficient during anaerobic digestion. However, CM, absence ionic form high presence inorganic carbon magnesium inhibits CaP granulation. In this study, was achieved first time treatment, using an up-flow sludge blanket (UASB) reactor preceded by acidifying continuously stirred tank (CSTR).

The use of methane fermentation in mesophilic conditions for the energy cow manure and additional co-substrates from farm can bring a small dairy (140 cows) financial benefits up to EUR 114,159 per year. Taking into account need pay emissions calculated as carbon dioxide equivalent, this profit could be reduced 81,323 With traditional direct manure, would drop by much 60% level 33,944 Therefore, introduction fees may significantly burden current farms.

In this study, cow manure was hydrothermally treated in a 2-litre reactor for 1 h at temperatures between 100 °C and 260 °C. Both the raw solid liquid products of hydrothermal treatment were characterized to understand fate inorganic elements assess suitability land applications energy recovery. Satisfactory elemental balances obtained organic most indicated that incorporated into solids with lower solubility, exception potassium sodium, which mostly solubilized process water; calcium chlorine also lesser extent water. Elemental composition surface functional groups showed hydrochar produced within carbonization range (180–260 °C) seemed better suited utilization as soil amendment than manure. The potential recovery lies anaerobic digestion water, from higher methane yields can be Lower are considered compromise safe manure, enhanced dewaterability. These findings help eliminate bottlenecks upscaling promote circular bio-economy.

This article presents the current state of biogas (biomethane) production technology with an example using cow manure from perspective photofermentation efficiency. In specialist farms, there is a problem waste management in form manure; analyses were carried out on photocatalysis process order to be able effectively produce biomethane based monosubstrate solutions (manure). Cow was tested for its elemental composition determine suitability this raw material production. The compared A, which stored 1 week (fresh sample, wet), and B, month (old dry).
