“…The process of composting can also be improved by pelletizing the compost material. The in-farm pelletizing of swine manure solid fractions co-composted with organic waste materials showed comparable properties with commercial pelletized organic fertilizers [48]. The addition of co-formulates could lower moisture content and increase the pellet strength.…”

The management of solid waste presents a challenge for developing countries as thegeneration of waste is increasing at a rapid and alarming rate. Much awareness towards thesustainability and technological advances for solid waste management has been implemented toreduce the generation of unnecessary waste. The recycling of this waste is being applied to producevaluable organic matter, which can be used as fertilizers or amendments to improve the soil structure.This review studies the sustainable transformation of various types of biomass waste such as animalmanure, sewage sludge, municipal solid waste, and food waste, into organic fertilizers and theirimpact on waste minimization and agricultural enhancement. The side effects of these organicfertilizers towards the soil are evaluated as the characteristics of these fertilizers will differ dependingon the types of waste used, in addition to the varying chemical composition of the organic fertilizers.This work will provide an insight to the potential management of biomass waste to be produced intoorganic fertilizer and the advantages of substituting chemical fertilizer with organic fertilizer derivedfrom the biomass waste.

“…Investigations shows that on farm granulation of swine manure solid fraction composted with different organic waste materials can turn into organic fertilizer formulations. Investigation results enhance the importance of composting as a way to increase livestock farming sustainability and produce better manure compost for wider agricultural uses (Romano et al, 2014). This paper is based on an investigation that aimed of determining physical properties of organic agricultural waste (cattle, cow manure compost, molasses) through new technology granules production and of granulated fertilizer impact on soil.…”

In recent years, the European countries recycle only 5−7% of bio-waste. One activity of the biological waste disposal is granulation. The production of fertilizer from animal manure with supplement represents an important area of environmentally friendly bio-fertilizer production. This paper presents an investigation of estimation manure compost physical-mechanical properties for reuse of organic waste − cattle and cow manure, sugar production waste − molasses through new technology pellets production and of granulated fertilizer impact on soil. The experimental manure samples produced by industrial methods and samples produced in the laboratory from the time period of 2014 to 2017 were investigated. The following physical – mechanical characteristics were estimated: biometric indicators (dimensions, mass), volume and density of raw material and pellets, material and pellet’s humidity and pellets strength. Experiments results have shown that the difference in limit strength between experimental and industrial organic compost pellets was about 5%. Experiments of fertilizers on the impact on soil shown that the amount of nutrients added to the soil depends on the rate of the granulated compost fertilizer. As the norm increases, organic carbon, humus, mobile phosphorus and potassium increase in soil. Increases in soil fertility, improved agrochemical properties, soil organic matter accumulation and humus increase. Granulated compost fertilizers have no effect on soil acidity. The presented results could be helpful to the development of the fertilizing process by the granulated compost fertilizer for improvement of soil quality in small farms.

“…This allows better handling and transportation of SF at greater distances (even at hundreds of km as an order of magnitude) in order to move nitrogen (N) from Nitrate Vulnerable Zones to others less prone to pollution. Furthermore, Romano et al [9] showed that pelletising homogenizes and further concentrates SF nutrients, thereby improving its fertilising and amending actions.…”

Abstract:The phytotoxicity of four different composts obtained from pig slurry solid fraction composted by itself (SSFC) and mixed with sawdust (SC), woodchips (WCC) and wheat straw (WSC) was tested with bioassay methods. For each compost type, the effect of water extracts of compost on seed germination and primary root growth of cress (Lepidium Sativum L.) was investigated. Composts were also chemically analysed for total nitrogen, ammonium, electrical conductivity and heavy metal (Cu and Zn). The chemicals were correlated to phytotoxicity indices. The mean values of the germination index (GI) obtained were 160.7, 187.9, 200.9 and 264.4 for WSC, WCC, SC and SSFC, respectively. Growth index (GrI) ranged from the 229.4%, the highest value, for SSFC, followed by 201.9% for SC, and 193.1% for WCC, to the lowest value, 121.4%, for WSC. Electrical conductivity showed a significant and negative correlation with relative seed germination at the 50% and 75% concentrations. A strong positive correlation was found for water-extractable Cu with relative root growth and germination index at the 10% concentration. Water-extractable Zn showed a significant positive correlation with relative root growth and GI at the 10% concentration. These results highlighted that the four composts could be used for organic pellet production and subsequently distributed as a soil amendment with positive effects on seed germination and plant growth (GI > 80%).
