- Description: Abstract: The overwhelmingly high volume of industrial waste generation in Harare, spurred the initiation of a study to explore the possibility of coming up with novel integrated waste management system framework to reduce the current waste load being deployed to the official dumpsite. An investigation into ways on how eco-industrial park framework development would achieve this was conducted. The study did lay the basis for industrial beneficial interaction among various potential manufacturing industry players; through identifying companies with potential to be part of the eco-industrial park for enhanced waste administration. The intended industrial symbiosis consideration to minimize waste generation as a strategy was muted by virtually clustering already existing firms. The work study guidelines were put in place to make recommendations for an industry wide eco-industrial park based waste management platform to enable utility sharing; energy, waste and byproduct exchange; creation of mutual waste sinks, and information exchange. As well as improving on input operational efficiencies at company level, with the view to accomplish improved protection of the environment. A survey study was undertaken on the industrial organizations in the four major industrial areas of Harare. To achieve this, a questionnaire was sent out to firms to gather data on: manufacturing facilities; quantities, type, sources and destiny of waste treatment; utilization of waste, byproducts and waste heat; energy consumption of production processes; operational performance and difficulties; and expected support from local authorities and government. Interviews were conducted with potential industrial participants and stakeholders, including municipality and environmental agency, to establish gaps for which the eco-industrial park would address. Material flow analysis was used in conjunction with the five-stage industrial ecology methodology to analyze the collected data and come up with the feasible virtual eco-industrial park prototype which covers the main industrial hubs of Msasa, Southerton, Graniteside and Workington. In the considered sample, 10% of respondents confirmed that they were involved in industrial symbiotic practices of one form or another to minimize waste generation. Solid waste constituted 63% of the total waste generated by the firms. Agro-based biodegradable waste contributed about 50% of the total waste. The major firms identified across the industrial sites, to form the basic eco-industrial park network for byproduct and waste exchange were: the cement plant, coal thermal power plant, gypsum plant, chemical and fertilizer plant, and, pulp and paper milling. Fly ash and gypsum were found to be the main byproduct inputs in cement production. Msasa industrial site was selected as the anchor site as, it had abundant land space available to accommodate further growth of incubation firms which would be incorporated over time as the park network grows. Low level waste and byproduct exchange by companies, confirmed that there was potential for implementation of eco-industrial park initiative through training of stakeholders, as well as adopting relevant technological innovation in converting biodegradable waste to biogas energy. As the economy is driven by a proliferation of micro-enterprises and Small to Medium Enterprises, inculcating a discipline of waste segregation at source would enable ease of waste recycling and reuse. Strict legal framework supported by institutional administration and government funding, to assist in network coordination and information dissemination, is critical for eco-industrial park activity realization.

This was done on a South African company which is into linen manufacturing and making uniforms for the hospitality industry. This was achieved by improving effective communication among departments to meet delivery dates. ERP framework was designed to reduce work in progress on the shop floor and inventory. Integration of firm’s activities, intra organizational communication and wider collaboration were some of the pillar considered in the process to achieve a reduction in working capital. Wastage in the form of material or energy, inventory, defects or wasted capacity, was eliminated for effectiveness. Reduction of product cycle times was done through minimizing set-up and delays, coordinating machine maintenance with production operations and optimizing space in order to better utilize workers, equipment and workstations.

The main thrust of this work was to develop theory on how DFE could be comprehensively and consistently managed in daily business situation of product development. It was realized that an integration of environmental management systems, design for Environment, and integrated product development was necessary to achieve this. It was found that an intersection existed where three areas needed to coexist. Hence, theory and a model needed to be developed that explained and guided the management of DFE in the industry. The use of DFE for foundry industry would go a long way in preserving the environment and reducing costs for production hence create more profits.

There was need to check gauges and machines, and determine need for some maintenance or overhaul work to be carried out as faulty machines could not produce quality good products. There was need for operators to be trained, new documents to be produced and actions for the future to be agreed on.

The processes involved stripping of over 70% of animal skin wet mass, to retain a refined product. It is this non-useable material which is contaminated with process chemicals that is a cause for environmental concern. Effort was made to explore areas that consumed the most resources, and had the most emissions, with a view to recover, reuse and recycle or substitute waste material generated in the tannery.

- Description: This study examines the impact of Total Productive Maintenance (TPM) implementation on an organization in terms of productivity and quality levels. The human resource aspect was investigated to assess motivation of operators through training to reduce set up times, change over stoppages, defects rate and resource wastage on the shop floor. Total Productive Maintenance (TPM) implementation case study was evaluated in addressing these short comings in a confectionary manufacturing plant.

- Description: Abstract: The study investigated the metal processing industry and established gaps in its application of cleaner production initiatives. Major processes were reviewed through use of material balance diagrams for typical operations. Upon which feasible CP options were generated to minimize waste and emissions from the metal industry. The specific framework guidelines for CP implementation were outlined for various metal industry sector processes.

- Subjects: Beverage manufacturing , Cleaner production technologies
- Type: Article
- Identifier: uj:5042 , http://hdl.handle.net/10210/13562
- Description: This study explores to improve the resource efficiency, waste water reduction and to reduce losses of raw materials in a beverage making industry. A number of cleaner production technologies were put across in this work. It was also noted that cleaner production technology practices are not only desirable from the environmental point of view, but they also make good economic sense, in their contribution to the bottom line by conserving resources like energy, raw materials and manpower, improving yield as well as reducing treatment/disposal costs. This work is a resource in promoting adoption and implementation of CP in other industries for sustainable development.
