Biodelignification of sugarcane shoots: agricultural waste management strategy as an alternative feed for ruminants

This research aimed to reduce the lignin content and increase the nutrients content of sugarcane shoots as forages for a ruminant. This research used an experimental method using a completely randomized design (CRD) in factorial patterns, whereas A factor was a type of fungi (Pleurotus ostreatus and Aspergillus oryzae), and B factor was biodelignification time (14. 21 and 28 days). The variables observed in the experiment were laccase enzyme activity, Crude Protein (CP) content, and the percentage of lignin decreased. The research results showed that biodelignification using Pleurotus ostreatus fungi for 28 days resulted: 1,62 U/ml of laccase enzyme activity, 9.23% crude protein content, and 12.83 % of lignin decreased. From this research, the best treatment for bio-delignification of sugarcane shoots was with Pleurotus ostreatus fungi for 28 days, producing the best sugarcane shoots with 9.23 % of crude protein 12.83% of lignin decreased.

Theoretical and legal definition of the concept of «agricultural waste»

The article provides a scientific and theoretical analysis of EU legislation, ukrainian legislation and legal doctrine in the field of agricultural waste management. Particular attention is paid to establishing features in the legal regulation of such activities. The author concludes that today, taking into account the need to implement EU legislation, there is a process of gradual formation of agricultural legislation aimed at solving problems related to agricultural waste management. It is based on the Laws of Ukraine of June 25, 1992 «On Veterinary Medicine», «On animal by-products not intended for human consumption», of May 18, 2017 «On state control over compliance with legislation on food, feed, animal by-products, animal health and welfare», of December 23, 1997 «On the basic principles and requirements for food safety and quality». In addition, the expediency of defining at the legislative level the concept of agricultural waste, understanding it as substances, materials and objects formed in the process of human agricultural activity, as well as plant and animal life, which completely or partially lost their consumer properties and have no further use (other than organic fertilizers) at the place of formation or detection and which the owner must dispose of by disposal or disposal. The article proposes to make changes to the Waste Classifier SC 005-96 «Waste Classifier», approved by the order of the State Statistics Service of Ukraine of February 29, 1996. № 89, by supplementing group 01 with forestry wastes (excluding wastes from forest processing, production of panels and furniture, pulp, paper and board) and fisheries.
