| Abstract |
Our actual context is reflected in the food chain increased demand worldwide, but at the same time is reflected also in the climate change which affects our chain of supply, meaning increase soil temperatures, lack of rain (drought) etc. On the other hand, our soil is drained of nutrients because soil is not resting between seasons. Having no more winters with abundant snow, agricultural fields are cultivated more than once during the year, with huge negative effects on the agricultural fields. Major changes must be considered, meaning that better soil management should be done. The first action required is to improve soil characteristics to serve the increased necessity of more food. There are natural ways to solve these challenges, and one of them is to create compost from the organic waste which humankind produces. In this way, we ensure a healthier balance, not using natural resources or chemical products and we introduce the organic waste back into the bio circular economy strategy that we have across Europe. The treatment of biowaste through composting is the most widespread biological method of organic waste treatment in the European Union. Biowaste composting plays an important role in the transition to a circular economy. The final product (compost), which is used in agriculture as a soil amendment or fertilizer, needs to be of extremely high quality to complete the loop of biowaste treated by composting. Under these conditions, the current study focuses on the potential for producing compost by mixing green waste with sewage treatment plant sludge. Within the parameters of the present experimental study, 75 cubic meters of compost were produced from 200 cubic meters of biowaste (sludge: green waste, 1:2 ratio). Due to the lack of specific standards and procedures (guidelines) for obtaining and validating high-quality compost that can be used in agriculture in the context of Romanian legislation in the field (Law 181/2020), reference values of physico-chemical parameters from regulations in force in various UE states were taken into consideration for the compost quality evaluation. |
