Bioplastic production in terms of life cycle assessment: A state-of-the-art review

Environmental Science and Ecotechnology, Journal Year: 2023, Volume and Issue: 15, P. 100254 - 100254

Published: Feb. 20, 2023

The current transition to sustainability and the circular economy can be viewed as a socio-technical response environmental impacts need enhance overall performance of linear production consumption paradigm. concept biowaste refineries feasible alternative petroleum has gained popularity. Biowaste become an important raw material source for developing bioproducts biofuels. Therefore, effective management systems biofuels are crucial employed pillars economy. Bioplastics, typically plastics manufactured from bio-based polymers, stand contribute more sustainable commercial plastic life cycles part in which virgin polymers made renewable or recycled materials. Various frameworks strategies utilized model illustrate additional patterns fossil fuel bioplastic feedstock prices various governments' long-term policies. This review paper highlights harmful fossil-based on environment human health, well mass eco-friendly alternatives such biodegradable bioplastics. Utilizing new types bioplastics derived resources (e.g., biowastes, agricultural wastes, microalgae) choosing appropriate end-of-life option anaerobic digestion) may right direction ensure production. Clear regulation financial incentives still required scale niche large-scale market applications with truly impact.

International Journal of Biological Macromolecules, Journal Year: 2023, Volume and Issue: 248, P. 125845 - 125845

Published: July 18, 2023

Sustainable food packaging is a necessary element to ensure the success of system, accomplishment which weighed in terms quality retention and ensured products safety. Irrespective raised environmental concerns regarding petroleum-based materials, sustainable analysis lab land assessment should be priority eliminate similar fates new material. Functionalized bio-based hydrogels are one smartest inventions that expected revolutionize industry. Although this review, focus relies on recent developments hydrogel natural biopolymers such as proteins polysaccharides from could obtained, challenges encountered hydrogel-based materials future prospects also discussed. Moreover, need for Life Cycle Assessment, stress certifications waste management system suggested can bring both into same recycling bins.

Catalytic Upcycling of Polyolefins

Chemical Reviews, Journal Year: 2024, Volume and Issue: 124(16), P. 9457 - 9579

Published: Aug. 16, 2024

The large production volumes of commodity polyolefins (specifically, polyethylene, polypropylene, polystyrene, and poly(vinyl chloride)), in conjunction with their low unit values multitude short-term uses, have resulted a significant pressing waste management challenge. Only small fraction these is currently mechanically recycled, the rest being incinerated, accumulating landfills, or leaking into natural environment. Since are energy-rich materials, there considerable interest recouping some chemical value while simultaneously motivating more responsible end-of-life management. An emerging strategy catalytic depolymerization, which portion C-C bonds polyolefin backbone broken assistance catalyst and, cases, additional molecule reagents. When products molecules materials higher own right, as feedstocks, process called upcycling. This review summarizes recent progress for four major upcycling strategies: hydrogenolysis, (hydro)cracking, tandem processes involving metathesis, selective oxidation. Key considerations include macromolecular reaction mechanisms relative to mechanisms, design transformations, effect conditions on product selectivity. Metrics describing critically evaluated, an outlook future advances described.

A Review of the Biomass Valorization Hierarchy

Sustainability, Journal Year: 2025, Volume and Issue: 17(1), P. 335 - 335

Published: Jan. 4, 2025

The sustainability of the planet is based on reducing use fossil fuels and greenhouse gas emissions. recovery biomass waste puts economically valuable materials into circulation, which can successfully replace would otherwise be sent to landfills. Based review several published works, we observe that referenced processes value or are not necessarily most profitable environmentally friendly. used methods valorize mainly researchers knowledge experience, neglecting some more appropriate developing technologies. valorization wastes should promote production products with highest added value, it must also friendly cost-effective. This manuscript proposes a hierarchy for various waste, from agricultural activities, urban solids food processing industries, even wood industries. proposed number recommendations aimed at increasing biomass, in order reach objective carbon neutrality comply principles circular economy.
