From plastic waste pyrolysis to Fuel: Impact of process parameters and material selection on hydrogen production

Ahmed S. Al-Fatesh et al.

Summary: Hydrogen, as an energy carrier, has the potential to replace fossil fuels and reduce environmental pollution. The accumulation of plastic waste materials poses a severe burden on the environment due to the increasing demand for plastics. Thermo-catalytic conversion of plastic waste materials to hydrogen and other fuels is a promising long-term solution to this environmental challenge, but the development of durable and high-efficiency catalysts is a potential challenge for researchers.

Lignin-induced sacrificial conjoined-network enabled strong and tough chitosan membrane for food preservation

Jing Luo et al.

Summary: Chitosan, as a natural green polymer, shows potential as a plastic replacement. However, the strength and toughness of chitosan limit its commercial use. By constructing a sacrificial conjoined-network, a high-performance lignin/chitosan composite film was successfully fabricated, which simultaneously improved tensile strength, elongation, and toughness. The composite film also exhibited excellent UV resistance, thermal stability, low oxygen permeability, and food preservation qualities. This lignin/chitosan composite represents a promising alternative to plastic.

Lignin valorization through polymer grafting by ring-opening polymerization and its application in health, packaging, and coating

Camila C. O. Santos et al.

Summary: The growing interest in developing biodegradable polymers as substitutes for non-biodegradable ones has led researchers to explore alternatives for sustainable materials. Lignin, widely produced by biorefineries and paper industries, has been found to play a crucial role in the preparation of polymers and composites through ring-opening polymerization (ROP). Its aliphatic and phenolic reactive hydroxyls can initiate cyclic ester monomers, and it also possesses antioxidant and anti-UV properties as well as biodegradability. Understanding the role of lignin in environmentally friendly materials can overcome current limitations. This review focuses on the polymer grafting onto reactive hydroxyls from lignin surface by ROP, and the use of grafted lignin in biodegradable polymer composites. The impact of lignin surface modification and the monomer-to-initiator ratio on the properties of prepared materials, such as mechanical, thermal, antioxidant, and UV absorbance properties, is discussed, with emphasis on applications in biomedical fields, as well as packaging and coatings.
