The global economy is threatened by the depletion of fossil resources and fluctuations in fossil fuel prices, and thus it is necessary to exploit sustainable energy sources. Carbon-neutral fuels including bio-oil obtained from biomass pyrolysis can act as alternatives to fossil fuels. Co-pyrolysis of lignocellulosic biomass and plastic is efficient to upgrade the quality of bio-oil because plastic facilitates deoxygenation. However, catalysts are required to produce bio-oil that is suitable for potential use as transportation fuel. This review presents an overview of recent advances in catalytic co-pyrolysis of biomass and plastic from the perspective of chemistry, catalyst, and feedstock pretreatment. Additionally, this review introduces not only recent research results of acid catalysts for catalytic co-pyrolysis, but also recent approaches that utilize base catalysts. Future research directions are suggested for commercially feasible co-pyrolysis process.

The relentless depletion of fossil fuels accentuates the urgent necessity for the sustainable synthesis of chemicals from renewable biomass. 5-Hydroxymethylfurfural (HMF), extracted from lignocellulosic biomass, emerges as a beacon of hope for conversion into value-added chemicals. However, the inherent susceptibility of its unsaturated aldehyde groups to excessive oxidation often culminates in undesired reactions, compromising both the yield and specificity of the desired products.

Effective management of antibiotic sludge (AS) is essential for disease prevention. This study investigated the co-pyrolysis of AS with polyurethane (PU) and rubber tires (RT), focusing on its key drivers, synergies, resulting products, and atmospheric (N versus CO) dependency. Composite pyrolysis index indicated superior co-pyrolysis properties of AS with PU or RT in the CO atmosphere compared with those in the N atmosphere.

Antibiotics in aquatic environments can foster the development of antibiotic-resistant bacteria, posing significant risks to both living organisms and ecosystems. This study explored the thermo-chemical conversion of cattle manure (CM) into biochar and assessed its potential as an environmental medium for removing nitrofurantoin (NFT) from water. The biochar was produced through the co-pyrolysis of CM and acid mine drainage sludge (AMDS) in a N condition.

Homostructure construction has been proven to be an effective method for boosting the photocatalytic activity of polymeric carbon nitride. However, the contribution of the intrinsic activity of molecular fragments in the catalytic performance of homostructured carbon nitride is yet to be explored. In this paper, a facile hydrogen-assisted strategy was used to synthesize triazine/heptazine intermolecular homojunctions (g-CN(MU-H)) with an ultrathin and defective structure, via the co-pyrolysis of melamine and urea precursors.
