“…Existing LCA studies on moulded pulp products were collected and compared, showing a wide range of purposes and scopes. The 11 LCA studies that were investigated comprised of one study on wood pulp, three studies on wood pulp, four studies on paper, two studies on moulded pulp products and one study on waste paper management . This is not expected to be a full list of LCA studies on wood‐based paper pulp, but it is nevertheless expected to provide decent insight into the life cycle.…”

Eco-friendly packaging such as moulded pulp products have gained commercial importance in the recent years. However, it remains a greatly under-researched area, and there is an arising need to consolidate the best practices from research and industry in order to increase its implementation. The goal of this paper is to give an overview of the main aspects involved in the manufacture of moulded pulp products. This includes a classification of moulded pulp products, historical and current applications, production processes, materials, mechanical properties and environmental sustainability. Moreover, based on the latest research in the field, an innovative drying technique that utilizes concepts derived from impulse drying is presented, and the implementation of this process technology is discussed. Copyright © 2017 John Wiley & Sons, Ltd. INTRODUCTIONMoulded pulp products, also referred to as moulded pulp or moulded fibre products, are primarily used for the packaging of manufactured products and for food-related carriers, such as food containers and serving trays. Because of form (geometry) and aesthetic limitations, moulded pulp products have mostly been limited to the egg tray market for many years. However, demand is now increasing because of their sustainable qualities.1 Environmental, social and economic concerns result in a growing search for more sustainable products and industrial processes. As it consists simply of water and wood fibres (i.e. primarily cellulose), moulded pulp is a renewable material and a biodegradable solution. The manufacturing process includes the recovery of discarded materials from manufactured and recycled products made of wood fibres, such as cardboard, newspapers and magazines. These qualities have enabled growing adoption within the packaging industry. Companies are eager to embrace alternatives to oil-based forms of packaging, because of government regulations and customer demands. Increasing R&D effort for standardizing design and testing practices is essential in order to meet the growing demand for eco-packaging with high-quality features.Reviews of the historical development in industrial applications of moulded pulp packaging, recent manufacturing innovations in the field and an overview of an industrial scenario in the UK are 5 While these articles give great insight into historical developments, they are outdated, and they report few of the recent innovations within the field. Consequently, not enough attention has been given to the different manufacturing processes, and there is a gap related to environmental considerations. By means of a comprehensive review, this paper fills the identified research gap by describing wide-ranging aspects of the manufacturing process of moulded pulp. The research method adopted in collecting and reviewing the publications focused the literature survey exclusively to moulded pulp. It excluded similar products used in the packaging industry, such as cardboard or honeycomb panels.The content has been organized to present the main aspects ...

A two‐step process of coagulation/flocculation followed by a simultaneous dual process (photocatalysis + photo‐Fenton) is developed to treat real pulp and paper (P and P) industry wastewater. The rigid stout color wastewater was treated using a sunlight‐responsive and cost‐effective Fe‐TiO2 composite using recirculating photoreactor with a total working volume of 4 L. The key point of this study is that the treatment is done in very less time (90 min), and it incorporates the idea of circular economy, as the composite is fabricated out of industrial rejects. The further intensification of the process was done by proper process optimization of both approaches. With an initial concentration of stout color (0.78 AU) and chemical oxygen demand (COD) (2200 mg/L), the optimized conditions gave a good reduction in % color and % COD, that is, 64.1% and 41.8% (1280 mg/L) after coagulation/flocculation and 89.74% and 53.12% (600 mg/L) after dual, respectively. The composite was characterized by using various techniques like field emission scanning electron microscopy (FESEM)/energy dispersive X‐ray analysis (EDAX), UV–visible diffuse reflectance spectroscopy (UV–vis DRS), and X‐ray diffraction (XRD) to check the catalyst composition, complexes formed between Fe‐TiO2, and the catalyst intactness in both fresh and 50 times recycled composite. A trapping study was also performed using various quenchers to confirm that OH• plays a major role in the present study among other radicals produced where 55–60% drop in color removal was seen. In order to foresee the commercial use of this study, the process' cost was also estimated. Practitioner points Industrial waste products were used to fabricate inert support that promoted the idea of circular economy/waste management. Iron from the waste used to execute photo‐Fenton process along with forming Fe‐TiO2 complex to make it visibly active composite. Enhanced production of OH radicals facilitated removal of stout color and COD from the real pulp and paper industry wastewater in just 90 min. Coagulation/flocculation followed by dual technique proved to be the best approach out of three different approaches applied. Composite showed excellent durability even after 50 recycles.
