Analysis of soybean production and potential secondary application

Abstract

In addition to the grains as the main agricultural product, the agricultural production of soybean also produces large quantities of plant residues in the form of soybean straw. The article focuses on the primary trends in soybean production worldwide, and Serbian’s current position in global production. The paper analysis the dynamics and structure of sown areas, gross harvest volumes and soybean yields in the world for the period 2006-2023 in the context of leading producing countries. Soybean straw is an agricultural leftover that yields up to 1.5 kg per kg of soybeans. The existing literature demonstrates the vast potential of soybean straw as an environmentally friendly source of carbon to produce chemicals, materials, fuels and energy similar to oil refineries. The possibility of using untreated soybean straw for the synthesis of building materials was considered. Different types of common cement were used as starting raw materials for synthesis. The characterization of two test samples was performed using X-ray diffraction analysis (XRD), light microscopy (LM), thermal conductivity and heat capacity measurement.
