BR24992914 "Integrated biotechnological solutions for production of value added products aimed at increasing the value of lignocellulosic by-products"
Supervisor: Bekbayev Kairat Serikzhanovich, candidate of technical sciences, Science professor
Relevance:
Emissions and accumulation of greenhouse gases from domestic and industrial sources have led to a significant buildup of carbon dioxide, primarily due to a fossil fuel-based economy. Lignocellulosic waste represents a highly promising renewable resource for the sustainable production of energy and chemicals. In this context, the concept of a circular bioeconomy is a promising strategy for generating profit and rational utilization of lignocellulosic waste. Such studies are also relevant to addressing objectives outlined in the strategic and programmatic documents of the Republic of Kazakhstan, including the "Concept for the Development of the Agro-Industrial Complex of the Republic of Kazakhstan for 2021–2030," the "Concept for the Transition of the Republic of Kazakhstan to a Green Economy," and the "Strategy for Achieving Carbon Neutrality in the Republic of Kazakhstan by 2060."
Target:
Development of a comprehensive set of scientific and technical solutions for producing value-added products (biohydrogen, biomethane, bioethanol, biobutanol, and biomass) from large-scale lignocellulosic by-products and waste from production and consumption, capturing and utilizing by-products, using hydrogen for extracting organic components, and improving the efficiency of meat and dairy production.
