“…The application of SWW to soil on small farms aims to dispose of waste that can cause environmental problems when not managed properly [5,65]. SWW can also serve as a biofertilizer, reducing costs by decreasing the use of conventional fertilizers and complementing soil fertilization based on the nutritional needs of each crop [66].…”

This study evaluates the long-term effects of swine wastewater (SWW) on relevant parameters for soil fertility, including calcium (Ca), magnesium (Mg), potassium (K) cations, cation exchange capacity (CEC), and organic matter (OM) in an agricultural area with 9 years of crop cultivation. Three types of SWW (raw, after leaving the biodigester, and after the manure plant) were analyzed with four application rates of SWW (0, 100, 200, and 300 m3.ha−1), associated or not with mineral fertilization, resulting in eight treatments. The study found that the long-term use of SWW had significant effects on soil parameters. Principal component analysis (PCA) was used to summarize the data. The soil’s calcium (Ca), magnesium (Mg), and cation exchange capacity (CEC) levels were higher in soybean compared to other crops and natural soil. Similarly, the treatment with 0 m3.ha−1 of pig manure and without mineral fertilization showed higher levels of these nutrients. In contrast, potassium (K) was found in greater quantities in oats, SWW from the biodigester, higher doses of manure, and with mineral fertilization. The crops had a higher organic matter (OM) content compared to the natural soil, with corn and raw SWW showing the most significant increase.

“…Faced with ever-increasing waste production and the challenges of waste management, national and European environmental policies are focusing not only on the need to reduce waste production, but also on waste recovery (Crovella et al, 2024). This involves reuse, recovery, recycling or any other action aimed at producing secondary primary materials (Directive 2006/12/EC).…”

Recycling biodegradable waste is one of the crucial stages in sustainable waste management. Recycling them for agricultural purposes can have a beneficial impact on environmental protection, with more organic amendment and fewer chemical fertilizers contaminating farmland and groundwater. This will support food production of the right nutritional quality, by increasing yields. The aim of this research was the biotechnological valorization of dewatered sludge as compost for agricultural soil fertilization. Compost was applied using the windrow method. The materials used for composting are dewatered sludge from the wastewater treatment plant, mixed with fillers, such as green and brown waste. The obtained results suggest that the finished products from heaps A, B and C show a significant level of stability. These results reinforce the viability of composting products as soil improvers, highlighting their stability, effective disinfection and compliance with environmental standards. This study showed that the compost from dewatered sludge can be a promising alternative to the use of chemical fertilizers in agricultural crops, with a view to improving yields.
