The Circular Economy2INTRODUCTIONThe Circular Economy is an environmental sustainability approach characterized by thecreation of economic models where there is no generation of advanced environmental impacts.This is an alternative model to the traditional model where the flow of energy and materials arelinear with no recycling and reuse of materials. Attaining a circular economy does not needvariations in the life of the disabled or extra cost on the mobility scooter manufacturingcompany, or loss of revenues. The sustainability of the manufacturing activities involvesequipment, services, infrastructure, and products and how their flows can be made linear throughrecycling and reuse as well as planning the future products and business model for the scootermanufacturing company.The components that are required for the manufacture of electric mobility scooter for thedisabled can be categorized into structural parts, electrical parts, and miscellaneous parts. Themiscellaneous parts include the bodywork, tyres, upholstery, and transmission systems. Theelectrical components include the sires, batteries, wires, circuit boards, and motors. Some of thesubtopics discussed in this paper include description of the components used in the manufactureof electric mobility scooters, the description of the lifecycle of the mobility scooter aftersustainability, and the short term and long term steps that can be taken by the company forensure sustainable system for the components required to mobility scootermanufacturing[ CITATION Mar171 \l 1033 ].Structural ComponentsThe structural components required during the process of manufacturing the electricmobility scooters for the disabled include the seat assembly, chassis, suspension, and wheels.
The Circular Economy3The number of wheels that are needed in the manufacture of mobility scooter depends on theparticular design of the scooter that the company is manufacturing at that particular moment. Thewheels can be made circular by first collecting all the used wheels from the dumped scooters andthose bought on second hand by the company, and then sorting them. The sorting processinvolves removal of other components making the wheels enable effective recycling orreuse[ CITATION Mit10 \l 1033 ].The metallic rims in the wheels can be reused in the manufacture of other wheels afterpainting and repairing them. The rims can also well be recycled by melting is a large furnacewith a considerable amount of energy and then purification to remove contaminants and toensure that the final product is of high quality. The molten metal can then be solidified throughcooling to make specific shapes of another structural component. The suspension system is acollection of shock absorbers and springs. There are two different types of suspension systemsthat are used in the manufacture of the mobility scooter, namely rear suspension and frontsuspension. The suspension is used in the insulation of both vehicle and rider from the shocks ofroads and also in keeping the wheels in the closest possible ground contact and provides controlof the scooter to the operator[ CITATION Rei16 \l 1033 ].The suspension system is majorly made up of the metallic materials and can be recycledthrough sorting the springs and shock absorbers separately and then carrying out melting,purification, and solidification processes. The molten metal can be solidified into new suspensionsystem which can be used to replace the old one in the operating mobility scooters or used in themanufacture of the electric mobility scooters. The chassis is primarily an internal structuralsection or the framework which supports the steering system, wheels, and transmission system.
The Circular Economy4Both the rear and front wheel are connected to the frame of chassis indirectly through the systemof suspension that is coupled with the wheels directly[ CITATION Ema18 \l 1033 ].The types of chassis that are used in the manufacture of mobility scooter by the companyinclude backbone tube, perimeter frame, underbone tube, and monocoque chassis. The materialsused in the manufacture of this chassis material include steel, aluminium, titanium andmagnesium. The flow of chassis materials can be made circular by recycling the chassis throughsorting to remove the secondary materials coupled with the chassis, and then melting the scrapmetal in a huge furnace as a huge amount of energy. However, this energy needed to melt andrecycle the metallic chassis is much lower compared to the energy required to produce metals bythe use of virgin raw materials. Before melting, the chassis should first be shredded to fit insidethe volume of the furnace. After melting, the resultant molten metal can be used in themanufacturing of different structural components that can be used in manufacturing newmobility scooter[ CITATION Rob18 \l 1033 ].The seat assembly is specifically meant for the disabled through the provision of greaterseating and riding comfort. Some of the attributes that are incorporated and determined whiledesigning the seat assembly for the mobility scooter by the company include foldable armrest,possible rotation of 45oto assist in outgress and ingress to the operator, and bucket type seat. Theflows of the materials used in assembling the seat can be circular through recycling by firstsorting the old seats. During the sorting process, all the components used in making the seat areseparated and the metallic components recycled through shredding, melting purification, andsolidification processes[ CITATION Fab10 \l 1033 ].
