Increased Greenhouse Gas (GHG) emissions from both natural and man-made systems contribute to climate change. In addition reducing the use of crude petroleum’s derived fuels, increasing tree-planting efforts sustainable practices, air pollution can be minimized through phytoremediation. Bio-fuel crops grown on marginal land sustainably address change, global warming, geopolitical issues. There are numerous methods for producing renewable energy organic inorganic environmental resources (sunlight, air, water, tides, waves, convective energy), technologies doing same with biomass different properties sources (food industry, agriculture, forestry). However, production bio-fuels is challenging contentious in many parts world since it competes soil growth may harmful environment. Therefore, necessary wildlife management techniques provide bio-energy while maintaining or even improving essential ecosystem processes. The second generation viewed as a solution serious issue. Agricultural lignocellulosic waste primary source second-generation bio-fuel, possibly bio-fuel future. Sustainable practices grow biomass, followed by their holistic conversion into ethanol desired yield productivity, key concerns employing mix successfully. this paper, we analyze various types bio-fuels, sources, impact sustainability.

Food waste represents a significant burden to management systems, exacerbating food insecurity and contributing global pollution, climate change, biodiversity loss. Supermarkets bear partial responsibility for waste, yet their sustainability efforts could also contribute solution. The present work aims at evaluating sustainable approach within supermarkets. To this end, we conducted multi-criteria analysis, incorporating the perspectives of academic experts 505 Italian consumers. Experts deemed residual value apps most solution in supermarkets, while emphasising influence price brand image. consumer analysis corroborated these results. Specifically, consumers expressed willingness pay 36 % less bag goods set expire 2–3 days, which increased 60 24 h. findings point opportunities mutual benefit between suppliers when is effectively managed store, thereby highlighting need further, product-focused research.

The transportation sector is marked by high emissions, and new sustainable solutions are required to solve this problem. Biomethane, also known as green gas, has the potential regenerate certain wastes, promoting resource circularity. This study aimed at evaluating profitability of small- medium-sized plants using organic fraction municipal solid waste (OFMSW) by-products, considering a incentive decree within mature biogas-biomethane market Italy. Net present value (NPV) was used key indicator, sensitivity, scenario, risk analyses were proposed. results showed that subsidy for by-products contributed across multiple contexts. Conversely, stringent values OFMSW led diminished treating substrate. Consequently, verified 100 m3/h with 300 OFMSW. break-even point analysis tariff determining project profitability, contingent on size substrate, ranged from 0.61 0.95 €/m3 0.76–1.01 by-products. provide valuable policy managerial insights, emphasizing support needed biomethane – renewable circular achieve twin goals energy independence low-carbon economy. contribute achievement Sustainable Development Goals 7 12.

The conversion of lignocellulosic agricultural waste into biofuels and other economically valuable compounds can reduce dependence on fossil fuels, harmful gas emissions, support the sustainability natural resources, including water, minimize amount in landfills, thus reducing environmental degradation. In this paper, wastes biomethane, biohydrogen, biodiesel, bioethanol, biobutanol, bio-oil is reviewed, with special emphasis primary secondary residues as substrates. Some novel approaches are mentioned that offer opportunities to increase efficiency valorization, e.g., hybrid systems. addition physical, chemical, biological pretreatment waste, some combined methods mitigate negative effects various recalcitrant processing (alkali-assisted thermal pretreatment, hydrolysis alkali bioaugmentation) evaluated. addition, production volatile fatty acids, polyhydroxyalkanoates, biochar, hydrochar, cellulosic nanomaterials, selected platform chemicals from described. Finally, potential uses recovered products discussed.

Biogas produced from anaerobic digestion of organic materials is emerging as a renewable energy source. Unfortunately, the large quantities CO2 contained in raw biogas greatly decreases its calorific value, thus efficient separation needed to upgrade biomethane. Several technologies, based on physical or chemical sorption CO2, are already available but they suffer some drawbacks, primarily related their negative impact environment and/or high requirements. Development alternative green upgrading technologies therefore needed, and research growing exponentially this field. As consequence, frequent assessment state art these rapidly evolving required. This review summarizes latest advances strategies for unconventional solvents such ionic liquids deep eutectic clathrate/semi clathrate hydrates, which low cost, ease operation environmental sustainability represent attractive advantages over conventional technologies. In particular, present work focused performance sorbent systems terms CO2/CH4 selectivity rather than absorption capacity. Indeed, most important parameter evaluating suitability practical applications, means negligible CH4 losses. The scientific results published last few years have been collected discussed serve guide researchers choosing optimal technology operating conditions perspective environmentally friendly biogas. Ionic excellent candidates upgrading, especially form hybrid systems, show best selectivity. Similarly, via hydrates can be considered efficient, cost-effective. However, drawbacks still need addressed.
