India generates over 500 million tonnes of agricultural waste annually, much of which is lignocellulosic biomass rich in silica, calcium, potassium, and carbon elements, which are favourable for catalytic applications. This study highlights the valorisation of abundant agro-wastes such as rice husk (up to 20% silica), coconut shell (74%-78% fixed carbon), sugarcane bagasse (45%-55% cellulose), and tamarind seed (rich in polysaccharides and carbon), as cost-effective and sustainable catalysts. Various preparation t...

Ash and slag waste (ASW) is a finely dispersed mineral material resulting from the combustion of brown and hard coal at thermal power plants. The involvement of ash and slag waste in industrial circulation is one of the effective ways to solve the issue of energy and resource saving. Utilization of ash and slag waste in industrial production will provide a solution to the environmental problem of environmental pollution by industrial waste - technogenic fine dust and harmful effluents by gradually reducing the rat...

A study was made of the influence of ZSM-5 zeolite on the composition and properties of the products of fast pyrolysis of flax shives in the temperature range of 350-750 -C. Zeolite ZSM-5 increased the heat of combustion of gaseous products, as well as the content of methane, ethylene, hydrogen, and carbon dioxide, which is probably associated with the processes of cracking of volatile products passing through a layer of a catalyst heated to high temperatures. The synthesis and study of zeolite catalysts ZSM-5 con...

As a result of the operation of thermal power plants used solid hydrocarbon fuel, ash and slag waste (ASW) is formed. ASW is a finely dispersed mineral material remaining as a result of burning brown and hard coal. The involvement of ASW in industrial turnover is one of the most effective ways to solve the issue of energy and resource conservation. The share of involvement of these types of waste in economic turnover in the European Union is about 98%, in China about 80%, and in Russia this indicator does not exce...
