Waste recycling is one of the key aspects in current day studies to boost the country’s circular economy. Recycling wood from construction and demolished structures and combining it with plastics forms wood-polymer composites (WPC) which have a very wide scope of usage. Such recycled composites have very low environmental impact in terms of abiotic potential, global warming potential, and greenhouse potential. Processing of WPCs can be easily done with predetermined strength values that correspond to its end application. Yet, the usage of conventional polymer composite manufacturing techniques such as injection molding and extrusion has very limited scope. Many rheological characterization techniques are being followed to evaluate the influence of formulation and process parameters over the quality of final WPCs. It will be very much interesting to carry out a review on the material formulation of WPCs and additives used. Manufacturing of wood composites can also be made by using bio-based adhesives such as lignin, tannin, and so on. Nuances in complete replacement of synthetic adhesives as bio-based adhesives are also discussed by various researchers which can be done only by complete understanding of formulating factors of bio-based adhesives. Wood composites play a significant role in many non-structural and structural applications such as construction, floorings, windows, and door panels. The current review focuses on the processing of WPCs along with additives such as wood flour and various properties of WPCs such as mechanical, structural, and morphological properties. Applications of wood-based composites in various sectors such as automotive, marine, defense, and structural applications are also highlighted in this review.

Utilizing waste streams to produce bio-based products has the potential to promote a circular economy. In addition, by incorporating biowaste into the circular economy, the production of sustainable bioproducts and bioenergy can be enhanced.

Materials research relating to bio-based polymers and composites has become the order of the day and several types of research are being undertaken on these materials.

Metal additive manufacturing (MAM) does not require any preface for its potential applications in various engineering and technological sectors. This article comprehensively discusses about the application of additive manufacturing technique specifically aerospace components. The structure of this article begins with an introduction to the current state‐of‐the‐art MAM technologies with the aid of patent landscape analysis. Any manufacturing starts with understating of the manufacturing cycle, so herein, the aerospace manufacturing cycle has been discussed commencing from the design phase and followed by the process parameters selection. The immediate effect after printing is the selection of evaluation parameters, wherein the surface texture analysis of AM printed components is discussed. This paves to discuss about the specific alloys such as titanium alloy and Inconel alloys which are widely used in the aerospace industry. This analysis paves a path for the utilization of these materials to manufacture specific aerospace components which are also discussed. Thereby, the impact of MAM over the aerospace sector and the guidelines to decision making on the suitable variant of MAM has been discussed clearly with the help of earlier literatures. Finally, the qualification and certification procedure are discussed therein, leading to the conclusion about the future scope of MAM in the aerospace sector.
