“…Huge amount of lignocellulosic rice straw is generated worldwide have the potential to reuse for bioethanol, biochar and pulp production (Bhattacharyya et al 2020;Huang and Lo 2019). Lignin is a polymer and high molecular weight that gave it rigidity and resistant against decomposition by different kinds of microorganisms, (Wang et al 2011).…”

We hypothised that lignin decomposition microbial consortium would make rice-straw decomposition faster as straw contain around 15-24% lignin. In this study, we isolated lignin degrading microbes from four natural sources and based on their ability towards lignin degradation four microbial strains and their combination (2 bacteria (LB 8, LB 18) and 2 fungi (LF 3, LF 9) were selected for rice straw decomposition. During straw decomposition greenhouse gases emission, enzymatic activities (β-glucosidase, cellulase, laccase), reduction in lignin content, weight loss and carbon nitrogen ratio (C:N) were quanti ed. The β-glucosidase, cellulase and laccase activities were higher in LB 18 + LF 3 consortium as compared to others. The lignin content was also decreased (8.9-9.5 to 6.6-7.9%) continuously from initial to 28th days of composting under LB 18 + LF 3. We found the microbial consortium LB 18 + LF 3 decomposed the rice straw faster as indicated by reduction of C:N ratio and reduction of lignin, hemicellulose and cellulose contents of 60, 19.2, 41.5 and 10.3%, respectively at 28th day from initial compare to other strains/consortium. However, higher, CH 4 and CO 2 uxes were observed at 28th days after composting (1.36 and 200.7 mg m − 2 h − 1 ) with no signi cant trend in N 2 O ux. Further, the consortium identi ed could be tested for in-situ straw decomposition with proper moisture management to evaluate its potential in eld condition. Therefore, we conclude that use of lignin decomposing microbial consortium has the potential to hasten the composting of rice straw in large scale, so viable option to reduce the menace of straw burning.

Graphical abstract Nursery cultivation is recognized globally as an intensive production system to support quality seedlings as well as to manage resources efficiently. Apart from other factors, potting media (PM) play a crucial role in determining the success of nursery cultivation. Worldwide, peat is the most commonly used substrate in PM because of its favorable physicochemical properties. However, due to ascending environmental and ecological concerns regarding the use of peat, a variety of new substrates have been used/tested by researchers/practitioners/growers as PM. Bark, coir pith, wood fiber, compost derived from various agro-residues, and vermicompost either alone or in combination are some of the commonly explored substrates and found to have the potential to replace peat to a greater extent. In lieu of availability, abundance, low cost, and no/low processing requirement, the use of agro-industrial residue (AIR) in the PM is the current trend. However, challenges associated with their adoption cannot be ignored. The present review is focused on providing collective information, scientific knowledge and detailed analysis of various AIR used in PM. The critical evidence-based review would help in developing a consistent approach for the identification, selection and characterization of a new renewable substrate. In addition, it would help in developing a rationale understanding of the practical and economic realities involved in the adoption of the same in PM.

“…Straw was chosen as one of the main wastes of cereal production with limited market value. Among all the bioplastics available on the market, the choice for prototype development fell on Mater-Bi®: a biodegradable and compostable bioplastic produced from corn starch by Novamont S.p.A. Its main disposal process is compost degradation, which is more convenient than incineration (Bhattacharyya et al, 2019). Lastly, all these components are compostable according to the EN 13432 standard (European Committee for Standardization, 2002).…”

Packaging waste is cause of serious concern. Each year hundreds of millions of tons of packaging are produced, therefore solutions that drastically reduce the environmental impact are urgently needed. While the recycling of metal, wood, paper and cardboard packaging have been subjected to significant improvement, however for some plastics, an efficient recycling or disposal has not been achieved so far. The European Union has implemented regulatory actions to legislate packaging and packaging waste by setting relevant short to medium-term targeting the recycling and disposal rate. In the last decade, the world global trend of the eco-sustainable packaging market is heading in this direction. The aim of this research is to develop an innovative and sustainable composite material for the production of tertiary packaging based on the combination of natural fibers and biodegradable biopolymers. In particular, the experimental application entailed the creation of prototypes consisting of straw and the biodegradable plastic Mater-Bi® which is named NeoPalea. The new material was prototyped to verify its physical characteristics and to determine its potential use for replacing current not-biodegradable packaging. The results show a good match with the characteristics of current polymers, suggesting the proposed material as a potential substitute for packaging applications.
