Generation of solid waste (SW) is a major problem in urban areas, thus its management is one of the important obligatory functions to not only urban local authority but also for the inhabitants. The citizens expressed their concerns about the waste management system in KCC and associated problems that they are encountering. Waste generation in Khulna City Corporation is around 455 tons of municipal solid waste/day and generation rate is now 0.75 Kg/capita/day on an average. Existing public utility services and facilities are not adequate to meet the demand of disposing these massive amounts of wastes and that’s why several problems are arising. There are some deterrents in the KCC’s solid waste Management system, arising from both the city corporation authority and the citizen of different levels. With a view to address the problem from through community participation, this paper intends to evaluate the potential of community based solid waste management approach in context of Khulna city.

Healthcare Waste Management

The management and treatment of healthcare waste (HCW) are of great concern owing to its potential hazard to human health and the environment, particularly in developing countries. Nowadays, various technological alternatives are gaining momentum as efficient and favorable waste management options across the world. However, selecting a suitable technology as well as an effective waste management approach for the treatment of HCW is still a challenging task for the municipal authorities. This study renders a comprehensive analysis of healthcare waste management (HCWM) practices and the technological options for its better management through a case study in Khulna, the southwestern division of Bangladesh. A number of healthcare establishments (HCEs) in the study area were selected and a questionnaire survey, as well as field investigations, was performed to find out the present status of HCWM and its limitations. An assessment of different technological alternatives was also carried out using Sustainability Assessment of Technologies (SAT) methodology which could pave the way for treating hazardous waste more efficiently in the Khulna metropolitan area. The study revealed that the overall HCW generation rate and hazardous HCW generation rate in Khulna city were 0.90 kg bed−1 day−1 and 0.18 kg bed−1 day−1, respectively. Assessment of management system revealed that 56% (n=38) of workers did not receive any form of training in the handling of hazardous waste. Around 54% (n=47) of them did not use any safety equipment or clothing. It has been found from the study that, among different technological alternatives based on the final score, incineration was the most suitable option for the treatment of hazardous waste in Khulna. Finally, some guidelines have been put forward to improve its existing management practices.

Enhancing demand side management is among the focus of Malaysia in its effort to pursue green growth throughout 2016 to 2020. Per capita waste disposal in the country is 0.3 to 1.2 kg and only a mere 2% is recycled. There is huge potential for reducing solid wastes in the country through a more sustainable waste management approach such as reducing, recycling and proper disposal.  This paper explores the result of a quantitative study conducted via a survey questionnaire on 118 households around Klang Valley. Applying the protection motivation theory, an ordinary least squares regression is applied to data to determine the significant factors affecting waste management behavior of households. Several elements of waste management behavior are investigated, such as waste avoidance, green purchases and reuse and recycle behavior. Results of study show that coping and threat appraisal processes significantly affect waste disposal and reuse and recycle behavior. For green purchasing and waste avoidance behavior, they are affected by coping appraisal but not threat appraisal process.  The study suggests that if the government can promote the information on how severe contaminated environments can have on humans and their surroundings, it can lead to more responsible disposal of waste as well as can increase reuse and recycling activities of households. Apart from that, highlighting the positive impact an individual person’s action can bring to the environment may increase reuse and recycling, waste avoidance and disposal and green purchase activities of the society, particularly the households.
