“…The authors also highlighted the need for life cycle assessment of materials using studies to quantify the overall balance in environmental impact. Reviewers focused on topic areas such as composites with glass fibres or particles [ 49 , 54 , 55 , 56 ], nanoparticles such as zinc oxides [ 57 ], nanoclay and carbon nanofibres [ 53 , 58 , 59 , 60 , 61 , 62 ], and finally other fillers reporting on calcium carbonate [ 63 ], copper slag waste [ 64 ] or residues from mining processes and basalt powders [ 65 , 66 ]. The motivation of this review was to fill the gap for inorganic fillers in sustainable applications for rotational moulding, considering the huge amount of by-products/wastes produced by industrial processes that are not sensitive to temperature and are available in powder form.…”

Rotational moulding is a unique low-shear process used to manufacture hollow parts. The process is an excellent process method for batch processing, minimal waste and stress-free parts. However, the process has drawbacks such as long cycle times, gas dependency and a limited palette of materials relative to other process methods. This review aimed to shed light on the current state-of-the-art research contributing towards sustainability in rotational moulding. The scope of this review broadly assessed all areas of the process such as material development, process adaptations and development, modelling, simulation and contributions towards applications carving a more sustainable society. The PRISMA literature review method was adopted, finding that the majority of publications focus on material development, specifically on the use of waste, fillers, fibres and composites as a way to improve sustainability. Significant focus on biocomposites and natural fibres highlighted the strong research interest, while recyclate studies appeared to be less explored to date. Other research paths are process modification, modelling and simulation, motivated to increase energy efficiency, reduction in scrap and attempts to reduce cycle time with models. An emerging research interest in rotational moulding is the contribution towards the hydrogen economy, particularly type IV hydrogen vessels.

“…All composites with this filler showed reduced tensile strength, especially over 10%; surprisingly, impact properties were not modified by adding the copper slag up to 10%. This same team proposed using basalt powder as a filler of polyurethane in reactive rotational molding [ 32 ], finding increased properties (tensile strength and modulus and hardness) with basalt loading of up to 20%, although obtaining lower homogeneity in wall thickness due to the formation of a foamed structure.…”

Rotational molding allows for obtaining hollow parts with good aesthetics and properties, having as main drawbacks the lack of pressure and the long cycle times, which limit the range of materials. Different fillers have been introduced in rotomolding to obtain composite materials assessed. This review has shown that glass fibers or particles are the most common material among them, although carbon fibers or clays have also been studied. In general terms, 10% loadings provide an increase in mechanical properties; higher loadings usually lead to a decrease in processability or final properties. When the filler consists of a micro- or nano-material, such as clay or graphene, lower loadings are proposed, generally not exceeding 3%. The use of fillers of an inorganic nature to obtain composites has not been as explored as the incorporation of lignocellulosic materials and even less if referring to waste materials or side streams from industrial processes. So, there is a broad field for assessing the processing and properties of rotomolded composites containing inorganic waste materials, including the study of the relationship between the ratio of filler/reinforcement and the final properties and also their preprocessing (dry blending vs. melting compounding).

“…The incorporation of basalt rock powder (BRP) as inorganic filler in the polymeric composite materials is of current interest. Despite so many works on the application of BRP as low-cost filler with polymers such as poly ethylene, poly propylene, epoxy and unsaturated polyester to formulate composites with excellent properties [15][16][17], but to the best of the authors' knowledge, no study has been conducted on applying basalt rock powder as inorganic filler for PVC. This work aimed to study the influence of adding varying ratios of basalt rock powder (BRP) on physical, mechanical and thermo kinetic properties of PVC reinforced BRP composites.…”

Polymeric composites filled with natural fillers are an emerging area in polymer science, and have recently attracted the attention of researchers. Because of their relatively good service properties, the major contributions of these natural fillers are lowering the cost of composite materials and producing faster molding cycles. In this study, the influence of micro particulate ground basalt rock addition on physical, mechanical, and thermal kinetic properties of polyvinyl chloride (PVC) reinforced basalt rock powder (BRP) composite material was investigated.Results showed that basalt rock powder (BRP) affect the physical, mechanical and thermal properties of the (PVC/BRP) composites. Increasing the BRP loading will produce a relative drop in water absorbability, also decrease the tensile strength and elongation at break, while causing an increase in hardness shore A and compression strength values. Moreover, thermal stability, activation energy, and entropy were increased with increasing BRP as proven by Thermogravemetric analysis (TGA), differential thermal analysis ( DTA), and differential scanning calorimetry (DSC).
