There is increasing use of biodegradable mulch films (BDMs) as an environmentally sustainable alternative to traditional in agriculture. However, their degradation fate and priming effect (PE) on native soil organic matter (SOM), including the form microplastics (MPs) after disintegration, are not well known. In this study, we investigated mineralisation a BDM (0–2000 μm MPs) its PEs three soils, i.e., Ferralsol, Vertisol Solonetz. The MPs were incubated at concentration 0.8% (w/w) separately soils temperatures 20, 30 40 °C for 150 days. We also evaluated MP particle size two (a Ferralsol Vertisol). Six fractions (i.e., <100, 100–250, 250–500, 500–1000, 1000–2000, 2000–4750 μm) A δ13C technique was employed determine proportion C mineralised from SOM owing distinct values. Temperature, type, interactions all key factors PEs. increased with 20 over time few exceptions. At °C, greater carbon clay content showed than Opposite trends observed °C. both exhibited similar suggesting that 'co-metabolism' may be dominant high temperatures. Furthermore, smaller tended induce mineralisation, whereas larger caused small particles.

Agricultural mulching is an important input for modern agricultural production and plays role in guaranteeing food security worldwide. At present, polyethylene (PE) still commonly used most countries around the world, which non-biodegradable, years of have caused serious white pollution. Lignin one three major components plant cell walls, it also main renewable natural aromatic compounds nature. Lignin-based composite film materials are green, biodegradable, show good prospects development field mulch. This paper introduces types, structure, application status lignin, summarizes preparation lignin-based its latest research progress, focuses on methods, examples mulching, looks forward to future mulching.

Renewable resources, such as biogas and volatile fatty acids from organic substrate digestion, are used to generate the poly(3-hydroxybutyrate-co-3-hydroxyvalerate), a biopolymer with mechanical thermal characteristics comparable fossil fuel-based plastic. A double-stage fermentation was simulated for generating poly(3-hydroxybutyrate-co-3-hydroxyvalerate) analysing role of odd carbon on 3-hydroxyvalerate building block inclusion. Valeric acid then supplied at various concentrations 100–2000 ppm since it responsible highest 3-HV molar fraction accumulated. The recovery granules through non-halogenated extraction also simulated: methyl ethyl ketone employed solubilising granules, mixture methanol water (7:3) applied during precipitation stage. yields ranged 78% 96%, basing amount polymer entering line, i.e. 0.5 2.5 kg, content 40%mol 20%mol, respectively. lowest were finally theoretical assessment biodegradability: maximum weight loss 90% obtained containing fraction, thus confirming dependence biodegradability molecular structure.

Bioplastics derived from polyhydroxyalkanoates (PHAs) are among the promising substitutes for unsustainable petroleum-based polymers. PHA-based polymers demonstrate superior chemical and physical properties, such as hydrophobicity, insolubility in water, iso-tacticity, UV resistance, hydrolysis absolute biodegradability. Compared with conventional plastics, bioplastics more beneficial due to their reduced carbon footprint, energy efficiency, biodegradability, biocompatibility, have hence revolutionized polymer industry. However, further research is needed explore novel strategies overcome limitations, decreasing water absorption brittleness, while increasing crystallization ability thermal degradation temperature. These constraints can be addressed by supplementing bioplastic synthesis process reinforcements plasticizers. The development adoption of biopolymers an environmentally friendly economically viable synthetic plastics imperative, considering degree subsequent exhaustion petrochemical supplies worldwide environmental contamination instigated industrial production plastics. goal this appraisal provide in-depth account most recent advancements generation various wastewater streams via use microalgae, harvesting technologies. microalgae higher quality made polymeric biomolecules include based on cellulose, starch, proteins, PHA, polyhydroxybutyrate (PHB), polyethylene (PE), polylactic acid (PLA), poly vinyl chloride (PVC). Various types manufacturing methodologies also been highlighted researchers capitalists alike investigate ways harness these renewable resources sustainable bioplastics.
