“…The evaluated results were in agreement with the work by Oladele and Afolabi [16]. Also, the machine was used in the production of waste paper pulp for the development of composite samples in the work titled; Flexural, water absorption and wear responses of green composites from bio-resources by Oladele et al, [17]. The machine has proven to be efficient in turning waste paper to pulp at the most convenient level of operation.…”

The current work report the design and fabrication of waste paper recycling machine that is efficient in tackling the challenges of waste paper disposal. The traditional methods of disposing waste papers have proven to be relatively expensive and unhealthy in many developing nations across the globe. Therefore, provision of low technological and cost effective machine for the recycling of these biodegradable wastes in more economical, healthy and safe for the environment is needed. Thus, the objective of this work was to design and fabricate a motorized waste paper recycling machine with slight modifications on the existing ones. The machine was designed to use rotary blades rotated by high speed electric motor followed by performance evaluation of the machine to determine its efficiency. Design calculations were used to ensure cost reliability and minimum energy consumption of the machine. The results showed that 25-30 kg of waste papers per hour were recycled and turned into pulp at a machine speed of 1440 rpm which implies high and good efficiency. The pulp was used for production of waste paper based composite samples with the addition of suitable binders.

“…Moreover, the rubber/treated WP provided the best mechanical performance, especially for NR. Corn husk was used as a second filler for the rubber/WP composites to produce low-cost and low-weight composites with improved properties [ 84 ]. The results reported an improvement in composite wear resistance and water resistance as the corn husk content increased (2, 4, 6, 8, and 10 wt.%), which is associated with the hydrophobic nature of the corn husk.…”

This review focuses on polymeric waste-paper composites, including state-of-the-art analysis with quantitative and qualitative discussions. Waste paper is a valuable cellulose-rich material, produced mainly from office paper, newspaper, and paper sludge, which can be recycled and returned to paper production or used in a new life cycle. A systematic literature review found 75 publications on this material over the last 27 years, with half of those published during the last five years. These data represent an increasing trend in the number of publications and citations that have shown an interest in this field. Most of them investigated the physicomechanical properties of composites using different contents of raw waste paper or the treated, modified, and cellulose-extracted types. The results show that polyethylene and polypropylene are the most used matrices, but polylactic acid, a biodegradable/sourced polymer, has the most citations. The scientific relevance of waste-paper composites as a subject includes the increasing trend of the number of publications and citations over the years, as well as the gaps identified by keyword mapping and the qualitative discussion of the papers. Therefore, biopolymers and biobased polymers could be investigated more, as well as novel applications. The environmental impact in terms of stability and degradation should also receive more attention regarding sustainability and life cycle analyses.

“…This, however, showed that biodegradable materials need to be added to polymers in order for them to be able to degrade after use. Nowadays, the attention of researchers worldwide is on how to ensure a proper disposal of used polymer products [32][33][34]. Therefore, there is a need to synergize between the required properties and the disposal mode for the sake of the environment.…”

In this study, wear resistance and some selected physical properties of pawpaw–glass fiber hybrid reinforced epoxy composites were investigated. Two different layers of pawpaw stem—linear and network structures—were extracted and chemically modified. Hybrid reinforced composites were developed comparatively from the two fiber structures and glass fiber using hand lay-up in an open mold production process. The wear resistance was studied via the use of a Taber Abrasion Tester while selected physical properties were also investigated. The influence of the fiber structure on the properties examined revealed that network structured pawpaw fiber was the best as reinforcement compared to the linearly structured fiber. The addition of these vegetable fibers to epoxy resin brought about improved thermal conductivity and increased the curing rate while the wear resistance of the corresponding developed composites were enhanced by 3 wt% and 15 wt% of fibers from linear and network pawpaw fibers. It was noticed that linearly structured pawpaw fiber had its best result at 3 wt% while network structured pawpaw fiber had its best result at 15 wt%.
