“…For example, India annually generates between 75-90 million tons of bagasse (wet mass) [65], which it mainly uses through incineration with cogeneration (electricity and heat generation) in medium and large sugar factories. In Brazil, the energy recovery of one ton of bagasse generates 12 kWh of electrical energy, 330 kWh of thermal energy (steam), and 16 kWh of mechanical energy [66].…”

Sugarcane is a lignocellulosic crop and the juice extracted from its stalks provides the raw material for 86% of sugar production. Globally, sugarcane processing to obtain sugar and/or ethanol generates more than 279 million tons of solid and liquid waste annually, as well as by-products; namely, straws, bagasse, press mud, wastewater, ash from bagasse incineration, vinasse from ethanol distillation, and molasses. If not properly managed, this waste will pose risks to both environmental factors and human health. Lately, valorization of waste has gained momentum, having an important contribution to the fulfillment of policies and objectives related to sustainable development and circular bioeconomy. Various technologies are well-established and implemented for the valorization of waste and by-products from sugarcane processing, while other innovative technologies are still in the research and development stage, with encouraging prospects. We propose a sustainable sugarcane processing flow and present an analysis of the physico-chemical characteristics of generated wastes and by-products. We emphasize the available possibilities of valorizing each waste and by-product, considering that they are important biomass resources for obtaining biofuels and a wide range of other products with added value, which will contribute to the sustainability of the environment, agriculture, and human health worldwide.

“…The overall economies of the agro-waste biomass can be improved by proper utilization of lignin to valuable products. It can be converted to gasoline range fuel additive or phenolic building block chemicals by either simultaneous lignin depolymerization or hydrodeoxygenation using hydrogen donating solvents (Abu-Omar et al 2021,Quereshi et al 2020). …”

The over dependency on conventional fossil energy resources is the consequence of high energy demand and excessive consumption of petroleum fuel, which turns out to be a major concern of 21st century. The burning of fossil fuel is an origin of greenhouse gas emission resulting in the utmost threat to environment subsequently which leads to global climate changes. As far as sustainability is concerned, fuels derived from organic or plant wastes overcome this downside and also are an established solution of the traditional oil resources depletion. In this context, exploration of agricultural residue appears to be a suitable alternate of non-renewable resources to support the environmental feasibility and meet the high energy crisis. Use of agricultural waste rather lignocellulosic biomass as a feedstock for biorefinery approach emerges to be an eco-friendly process for the production of biofuel and value-added chemicals intensifying the energy security. Therefore, a prospective choice of this renewable biomass for the synthesis of green fuel such as biobutanol, bioethanol keeps away food versus fuel dilemma and also comes up with favorable outcome in terms of cost effectiveness. Exploiting different agricultural biomass and exploring various biomass conversion techniques, biorefinery generates bioenergy in a strategic way which eventually fit in circular bioeconomy. The view of bioeconomy highlights the fruitful use of agricultural waste biomass in biorefinery acquiring such a system so that the by-products can be further utilized with low or no waste generation to maintain the sustainability and circularity of economy which are critically described.
