ABSTRACT
Many industries, including leather industry, are faced with high expenditure for solid organic waste treatment and disposal.Organic biopolymers represent a source of raw material for agriculture, because the composition of protean wastes provides enough elements to improve composition and rehabilitation of degraded soils.The main target of this scientific paper is investigating the development possibilities for various multicompound systems of biodegradable polymers and studying the effects of these complex products on the structure and chemical and physical characteristics of degraded or contaminated soils (having a poor level of organic matter or submitted to a strong erosion process). All treatments applied to wastes aim at substantially reducing environmental pollution. Complex characteristics of protean wastes from the leather industry are approached by accurately determining waste hide chemical composition and various possibilities of recovery and recycling using biotechnologiesThe novelty resides in the theoretically-based practical indications regarding the rational application of complex polymeric products – biofertilizers – on various types of soil (sandy, salty, eroded, dumps etc.) depending on the requirements of soil remediation and nutrition specific to agricultural plants. The work presents a new pilot technology for biochemical decay of the tannery protein wastes and use of the resulted products as fertilizers.
