The Circular Economy 2INTRODUCTIONThe Circular Economy is an environmental sustainability approach characterized by the creation 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 are linear with no recycling and reuse of materials. Attaining a circular economy does not need variations in the life of the disabled or extra cost on the mobility scooter manufacturing company, or loss of revenues. The sustainability of the manufacturing activities involves equipment, 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 scooter manufacturing company. The components that are required for the manufacture of electric mobility scooter for the disabled can be categorized into structural parts, electrical parts, and miscellaneous parts. The miscellaneous parts include the bodywork, tyres, upholstery, and transmission systems. The electrical components include the sires, batteries, wires, circuit boards, and motors. Some of the subtopics discussed in this paper include description of the components used in the manufacture of electric mobility scooters, the description of the lifecycle of the mobility scooter after sustainability, and the short term and long term steps that can be taken by the company for ensure sustainable system for the components required to mobility scooter manufacturing[ CITATION Mar171 \l 1033 ]. Structural ComponentsThe structural components required during the process of manufacturing the electric mobility scooters for the disabled include the seat assembly, chassis, suspension, and wheels.

The Circular Economy 3The number of wheels that are needed in the manufacture of mobility scooter depends on the particular 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 process involves removal of other components making the wheels enable effective recycling or reuse[ CITATION Mit10 \l 1033 ]. The metallic rims in the wheels can be reused in the manufacture of other wheels after painting and repairing them. The rims can also well be recycled by melting is a large furnace with a considerable amount of energy and then purification to remove contaminants and to ensure that the final product is of high quality. The molten metal can then be solidified through cooling to make specific shapes of another structural component. The suspension system is a collection of shock absorbers and springs. There are two different types of suspension systems that are used in the manufacture of the mobility scooter, namely rear suspension and front suspension. The suspension is used in the insulation of both vehicle and rider from the shocks of roads and also in keeping the wheels in the closest possible ground contact and provides control of the scooter to the operator[ CITATION Rei16 \l 1033 ]. The suspension system is majorly made up of the metallic materials and can be recycled through 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 the manufacture of the electric mobility scooters. The chassis is primarily an internal structural section or the framework which supports the steering system, wheels, and transmission system.

The Circular Economy 4Both the rear and front wheel are connected to the frame of chassis indirectly through the system of 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 company include backbone tube, perimeter frame, underbone tube, and monocoque chassis. The materials used in the manufacture of this chassis material include steel, aluminium, titanium and magnesium. The flow of chassis materials can be made circular by recycling the chassis through sorting to remove the secondary materials coupled with the chassis, and then melting the scrap metal in a huge furnace as a huge amount of energy. However, this energy needed to melt and recycle the metallic chassis is much lower compared to the energy required to produce metals by the use of virgin raw materials. Before melting, the chassis should first be shredded to fit inside the volume of the furnace. After melting, the resultant molten metal can be used in the manufacturing of different structural components that can be used in manufacturing new mobility scooter[ CITATION Rob18 \l 1033 ]. The seat assembly is specifically meant for the disabled through the provision of greater seating and riding comfort. Some of the attributes that are incorporated and determined while designing the seat assembly for the mobility scooter by the company include foldable armrest, possible rotation of 45o to 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 first sorting the old seats. During the sorting process, all the components used in making the seat are separated and the metallic components recycled through shredding, melting purification, and solidification processes[ CITATION Fab10 \l 1033 ].
