ClearLignocellulosic biomass from agricultural waste to the circular economy: a review with focus on biofuels, biocomposites and bioplastics
This review examines how agricultural waste rich in lignocellulose can be converted into biofuels, biocomposites, and bioplastics as sustainable alternatives to petroleum-based products. Recent advances in biorefinery technology have improved the ability to process plant-based waste into a range of useful materials. Replacing conventional plastics with bioplastics from agricultural waste could help reduce both plastic pollution and greenhouse gas emissions.

Bio-based plastics in a circular economy: A review of recovery pathways and implications for product design
Researchers reviewed how bio-based plastics — made from renewable plant sources — can be recovered and recycled at end-of-life, finding that the feasibility of eight different recovery methods depends heavily not just on plastic chemistry but on how products are designed, and offering guidance for designers to improve recyclability.
Economia Circular E Desenvolvimento Sustentável: Compostabilidade, Biodegradação E Inovação Em Biopolímeros E Compósitos Renováveis Para Aplicações Estruturais, Agrícolas E Embalagens
This review paper summarizes research on new plant-based plastics that can break down naturally in the environment, unlike regular plastics made from oil. These eco-friendly materials could replace traditional plastic in food packaging and farming, potentially reducing the tiny plastic particles that end up in our food and water. However, the technology still needs improvements and better waste management systems before these biodegradable plastics can widely replace regular plastics.

A review of recent innovations in biopolymer-based materials for various applications assessed how bio-derived polymers are being developed to reduce reliance on fossil-fuel plastics. The transition to biopolymers is relevant to reducing the long-term sources of microplastic pollution.
Nanocellulose Hybrid Lignin Complex Reinforces Cellulose to Form a Strong, Water-Stable Lignin–Cellulose Composite Usable as a Plastic Replacement
This study developed a strong, water-stable composite material made from cellulose and lignin extracted from agricultural waste (sugarcane bagasse), as an eco-friendly alternative to plastic. The lignin-cellulose composite showed dramatically improved wet strength compared to regular cellulose sheets, demonstrating potential as a biodegradable plastic replacement that would not generate persistent microplastic pollution.
Biocosmetics: technological advances and future outlook
Researchers reviewed emerging biocosmetics technologies, examining how bio-based and naturally derived ingredients are being extracted and formulated to replace conventional fossil-fuel-derived cosmetic components, with a focus on circular economy manufacturing and biodegradable packaging.
Towards a Circular Economy of Plastics: An Evaluation of the Systematic Transition to a New Generation of Bioplastics
This review evaluates the transition from petroleum-based plastics to bioplastics within a circular economy framework, assessing the sustainability, production challenges, and environmental trade-offs of current bioplastic alternatives.

The study demonstrated that this approach addresses both the microplastic pollution problem and fossil fuel dependence while enabling end-of-life recyclability.
Renewable cellulosic nanocomposites for food packaging to avoid fossil fuel plastic pollution: a review
Researchers reviewed how cellulose nanoparticles extracted from plant biomass can replace petroleum-based plastics in food packaging, finding that adding just 1–5% cellulose nanoparticles significantly improves strength, reduces oxygen and water vapor permeability, and keeps packaging biodegradable. The review positions cellulose nanocomposites as a scalable, eco-friendly alternative to fossil-fuel plastics that contribute to microplastic pollution.

Bioplastics in the circular bioeconomy: Production pathways, biodegradation mechanisms, and environmental implications
This comprehensive review examines how bioplastics — plastics made from renewable biological sources — fit into a circular economy, covering how they are produced, how microorganisms break them down, and the environmental risks when degradation is incomplete. A key concern is that even bio-based plastics can form microplastics if they do not fully degrade in real-world conditions like marine or soil environments, meaning that simply switching to bioplastics does not automatically solve the microplastic pollution problem.

This review examines recent advances in using lignin, a natural plant polymer, as a component in composite materials across various industries. Researchers highlight how lignin-based composites can serve as biodegradable alternatives to conventional plastics in packaging, construction, and other applications. The study suggests that scaling up lignin-based materials could help reduce dependence on petroleum-derived plastics and the resulting microplastic pollution.
