Biofertiliser for arable land - return nutrients back to the soil.
Inedible shells, residues and leftovers contain many important nutrients that can be recovered by returning them to the soil. Bio-waste can be turned into climate-smart biofertiliser, so we don't need to import mineral fertiliser from elsewhere. It helps save the soil.
Biofertiliser from bio-waste has a high nutritional value and contains many of the nutrients our crops need, such as phosphorus and nitrogen. Mineral fertilisers are imported into Finnish farmland and have a much greater negative impact on the environment. The production of mineral fertiliser requires a large amount of energy, and the phosphorus produced in the process also runs out over time. From an environmental point of view, it is better to use biofertilisers that reuse the phosphorus from the bio-waste.
Phosphorus is a mineral that is a major plant nutrient and the eleventh most abundant element in the earth's crust. At EU level, phosphorus is at the top of the list of raw materials at risk of running out in the long term. When cereals are harvested, a certain amount of phosphorus is removed from arable land. It is a nutrient that needs to be replaced so that arable land does not become depleted or produce lower yields and low-nutrient crops. With biofertiliser from your biowaste, we can put nutrients back into the soil.
Nitrogen is produced in many biological processes and, like phosphorus, is essential for life on Earth. In a biogas plant, nitrogen is converted into a form that is easier for plants to absorb and becomes biofertiliser.
