Implementation Analysis of the Cleaner Production Concept in Solid Waste Management among Food Businesses along Ryacudu Street, Sukarame District, Lampung Province, Indonesia

In the midst of city or regional growth and transformation, the establishment of fresh commercial zones often arises from the development of infrastructure and enhancements to roads, exemplified by the rejuvenation of Jl. Ryacudu in Bandar Lampung. The recent enhancements to Jl. Ryacudu, supervised by the Public Works and Construction Agency, have given rise to a thriving business center featuring an assortment of shops, cafes, restaurants, minimarkets, and various services lining both sides of the thoroughfare. Consequently, the increased activities have led to a proportional rise in waste production, especially within the food industry sector. Thus, effective environmental management is urgently required to prevent any adverse ecological impacts arising from the solid waste produced. This study aims to evaluate the current status of waste management in the food industry sector, focusing on both its effectiveness and efficiency. Additionally, the study proposes waste management strategies, emphasizing the adoption of the cleaner production concept, incorporating the principles of the 3R system (Reduce, Reuse, Recycle). The study's findings reveal that the complete implementation of the 3R system has yet to be achieved in the current setting. Nonetheless, the effectiveness and efficiency of the current solid waste management practices are considered satisfactory. Furthermore, the preparedness to adopt the 3R approach has been confirmed, indicating a promising path towards sustainable waste management practices within the restaurant industry.

Multi-objective optimization of life cycle assessment of integrated waste management based on genetic algorithms: A case study of Tehran

Abstract The ever increasing population of the cities and wastes produced by them has compelled many researchers and authorities to find a solution to this problem. The environmental and economic problems are among the challenges in municipal solid waste management (MSWM). Integrated solid waste management (ISWM) is a comprehensive method which deals with these problems through different combinations of technologies like anaerobic digestion (AD), composting and landfill. In this study, life cycle assessment (LCA) has been used to optimize the solid waste management of the city of Tehran. The primary objective of this study is finding the most optimal case with minimum carbon dioxide (CO2) production and energy consumption by considering economic data. Two different scenarios have been defined to do the investigations. In the first scenario, the current status of waste management in Tehran has been considered while in the second scenario, the system is upgraded by implementing state-of-the-art technologies like AD and landfill gas recovery. An LCA software, called IWM-2 was used for calculating the environmental load of each scenario and writing life cycle inventory. Both scenarios are once optimized by considering two objectives and once with three objectives, in order to find the optimal amount of waste entering each unit of waste management system being identified. It was concluded that utilizing newer technologies (second scenario) not only has less cost but also their saving of CO2 and the consumed energy is 901 t and 3,389 GJ less than the first scenario.

Municipal solid waste characterization, quantification, and management: A case study in Shadegan International Wetland region, Iran

Thepresent study aimed to investigate the description and determination of municipal waste management in seven cities located in Shadegan wetland region, Iran. Some parameters were evaluated, including the waste generation rate, weight density rate, moisture content, pH, and carbon-to-nitrogen (C/N) ratio. In addition, the current status of waste management in the region was assessed using a simple questionnaire and via interviews with households and field surveys. According to the findings, the generation rate of solid wastes was 0.55-0.8 kg/capita/day. The wastes contained approximately 70% of corruptible materials, more than 12% of plastic, and approximately 9% of paper and paperboard. The density, moisture content, pH, and C/N were estimated at 3,242 kg/m, 72.7%, 5.6, and 23.4, respectively. In Shadegan wetland region, recycling was active through the informal sectors, while there was no definite program for source reduction and recycling. Daily collection operations were carried out with no specific programs and prioritization in determining the route of the vehicle and performed manually in optimal conditions. Moreover, the final disposal was observed to be poor and in the dumping form. The obtained results indicated that the wastes in the region had considerable potential for recycling and composting. Therefore, it is recommended that integrated waste management be applied through the improvement of the regulations, environmental education, development of source reduction programs, organized recycling, mechanization of waste collection, establishment of central composting plants, and selection and design of safe landfills in order to achieve optimal outcomes.

Current status of waste management in Botswana: A mini-review.

Effective waste management practices are not all about legislative solutions, but a combination of the environmental, social, technical, technically skilled human resources, financial and technological resources, resource recycling, environmental pollution awareness programmes and public participation. As a result of insufficient resources, municipal solid waste (MSW) in transition and developing countries like Botswana remains a challenge, and it is often not yet given highest priority. In Botswana, the environment, public health and other socio-economic aspects are threatened by waste management practices due to inadequate implementation and enforcement mechanisms of waste management policy. This mini-review paper describes the panorama of waste management practices in Botswana and provides information to competent authorities responsible for waste management and to researchers to develop and implement an effective waste management system. Waste management practices in Botswana are affected by: lack of effective implementation of national waste policy, fragmented tasks and overlapping mandates among relevant institutions; lack of clear guidelines on the responsibilities of the generators and public authorities and on the associated economic incentives; and lack of consistent and comprehensive solid waste management policies; lack of intent by decision-makers to prepare national waste management plans and systems, and design and implement an integrated sustainable municipal solid waste management system. Due to these challenges, there are concerns over the growing trend of the illegal dumping of waste, creating mini dumping sites all over the country, and such actions jeopardize the efforts of lobbying investors and tourism business. Recommendations for concerted efforts are made to support decision makers to re-organize a sustainable waste management system, and this paper provides a reference to other emerging economies in the region and the world.

Current status of waste management at home-visit nursing stations and during home visits in Japan

A questionnaire survey was conducted with the aim of examining the problems involved in the disposal of infectious waste at home-visit nursing stations and in its handling during home visits by nurses. From among the home-visit nursing stations registered with the National Association for Home-Visit Nursing Care, 1,965 offices were selected at random and questionnaires were sent to the selected offices. Nurses at 1,314 offices (66.9 %) responded to the survey and responses from 1,283 offices were identified as suitable for analysis after excluding 26 offices that closed and five offices whose main field of care was psychiatry. Offices were classified by management configuration. Offices attached to hospitals were classified as “attached office” and all others were classified as “independent office”. More attached office nurses recovered medical waste from patients’ homes than did independent office nurses. They were also more likely to transport waste with them during the course of a day’s visits. There was a significant difference between attached and independent offices in the burden of expense for waste disposal. Both offices have strong concern about waste treatment containers and handling in improvement in home medical care (HMC) waste disposal. Thus, in order to alleviate these concerns, it is necessary to provide nurses with containers for medical waste suited to home-visit nursing care and tools for preventing injuries. Japanese government should address HMC waste disposal more comprehensively through necessary legislation, subsidization and standardization.

Domestic waste levels and an assessment of their current management strategies in Yenogoa Metropolis

The quantities and types of domestic solid wastes were determined for the purposes of planning and effective management of wastes in the Yenagoa metropolis. The current status of waste management in the metropolis was also assessed to identify the problems and prospects for effective waste management. The study shows that with a per capita daily waste production of 0. 189±0.039 kg, an average of about 28, 350 kg of waste are produced daily in Yenagoa metropolis. About 83% of the wastes produced were food wastes made up mainly of yam and plantain peelings. As regards current status of waste management, the study observed that, there was no equipment available for the management of domestic solid waste and no final dumping site for sanitary disposal of wastes was available. The major problems militating against the effective management of wastes were the lack of awareness on the part of the citizenry of the importance of proper waste disposal; the non-availability of collection points and the lack of political will of the relevant ity to meet the demands of proper waste management.
