The paper focuses on collection of information on recent multifaceted usage of biomass materials with critical examination on its sustainability. The use of biomass is becoming popular, with wide global acceptance as it is considered as green technology. The use of biomass products across industrial parallels, the material combination and production processes were elucidated in this paper. Biomass materials are seen as affordable alternative to conventional materials for domestic and industrial applications. The multifaceted use of biomass, which includes, energy generation, metallurgical applications, construction purposes, reinforcement in metal matrix composite, microelectromechanical system, biochemical and traditional medicine were discussed. This underscores the need to develop a sustainable plan to meet with its diverse usage to be beyond laboratory efforts. This paper examined whether the availability of biomass can sustain its multifaceted usage or not. It also examined the modalities to ensure sustainable use of biomass. Different policies were highlighted and discussed in line with continuous multifaceted use of biomass.

“…Furthermore, these materials are frequently disposed in an open land resulting in environmental contamination. Agro-waste materials such as rice husk ash (RHA) [14][15][16], groundnut shell ash (GSA) [17,18], coconut shell ash (CSA) [18,19], melon shell ash (MSA) [20] have been utilized by the researchers as reinforcing materials for improving the properties of AMC's. These AMC's can find application in automotive, aerospace, and construction materials [21,22].…”

Aluminum matrix composites (AMCs) have been extensively studied primarily due to higher strength-to-weight ratio, lower cost, and higher wear resistance properties. However, increasing demand for economical and energy-efficient materials in the automotive, aerospace and other applications is tailoring research area in the agro-based composite materials. Therefore, the aim of this systematic review work is to study the influence of agro-based reinforcements on the tribological and mechanical properties of AMC's processed by various techniques. It was observed that the processing conditions can be designed to obtain uniform structures and better properties AMCs. The agro-waste reinforcement materials, such as rice husk ash, bamboo stem ash, coconut and shell ash can result in a reduction in the density of AMC's without compromising mechanical properties. Moreover, the efficient utilization of the agro-waste leads to a decrease in manufacturing cost and prevents environmental pollution, hence, can be considered as a sustainable material. The state-of-the-art revealed that the agro-based reinforcements do not form brittle composites, as in the case of ceramic reinforced composites. Hence, the study concludes that the agrobased AMCs have great potential to act as a replacement for costly and environmentally hazardous ceramic reinforced-AMCs which can especially be used in various automotive applications that demand higher strength-to-weight ratio, lower cost, and higher wear resistance.

“…Moreover, energy requirement for processing of these wastes to be made suitable for reinforcement purpose is also lesser in comparison to processing of synthetic reinforcements. Mustard husk ash, 22 melon shell ash, 23,24 coconut shell ash, [25][26][27] bagasse ash, [28][29][30] bean pod ash, 31 breadfruit seed hull ash, 32 bamboo leaf ash, 33 marble dust, 34 304 stainless steel sawdust, 35 etc. have been successfully utilized by researchers for fabricating AMMCs.…”

This paper investigates dry sliding friction and wear behavior of AA7075 composites reinforced with rice husk ash and carbonized eggshells. Composites with varying weight percentages of rice husk ash and carbonized eggshells in the range of 0–5 wt.% were fabricated through stir-casting technique. Density, porosity content, and microhardness were computed before tribological testing. Friction and wear tests were conducted on pin-on-disc type tribometer at room temperature. The samples were tested at different loads (10–50 N) with constant speed of 1 m/s and constant sliding distance of 1500 m. Samples were also tested at different sliding speeds (3 and 5 m/s) with constant normal load of 30 N. The addition of natural reinforcements decreased the density of composites. Microhardness of sample having 5 wt% rice husk ash increased by 15.08% over base composition. Maximum wear resistance was shown by sample with 5 wt% rice husk ash. Highest coefficient of friction was shown by sample with 3.75 wt% rice husk ash and 1.25 wt% carbonized eggshells. Wear loss varied directly with increasing load and sliding speeds for all composites, whereas coefficient of friction increased with increasing load and decreased with increasing sliding speed for all composites. Delamination and ploughing are dominant wear mechanisms at low speed whereas ploughing is the dominant wear mechanism at high speed as depicted by scanning electron microscopic images of worn surfaces. Composites with improved wear-resistant properties can be used for different tribological applications particularly in automotive industry.
