Nearly 80% of all illness in Bangladesh is related to water and sanitation. The combined rate of enteric diseases in Bangladesh is the highest in the world. 30% of all the deaths of children under 5 are due to diarrhoea, claiming more than 200,000 lives annually. Environmentally sound human waste management, along with personal hygiene awareness, are of critical importance to the prevention of faecal-oral disease transmission. present rural sanitation coverage is about 3%. A national target has been set to ensure that 13% of the rural poor will be covered under the human waste management programme by 1990, the end of the U.N. Water Decade. This however, contrasts with the similar target of 77% for the rural water supply programme, which received higher resource allocation and priority for a much longer period. This lack of correlation between water and sanitation has highly reduced the positive health impact of these developments. An affordable human waste management programme for the rural people, where 87% of the total population lives under conditions of the greatest poverty and underdevelopment, urgently needs serious and realistic consideration in the context of the limited resource prospects for future years. This report addresses the above issues and describes the commendable momentum that has been gained through the continuous efforts of national planners and policy makers. It is hoped that this might in the near future, through the rural human waste management programme, produce the long desired continual reduction of faecal-oral disease transmission.

The purpose of the study presented in this text is to show the influence of COVID-19 on waste management systems and circular economy stream, and their impact on circular economy, particularly the economic impact of the pandemic on the waste management sector, impact on circular economy objectives’ implementation as well as additional challenges like the need for hygienization of waste streams during different implementation efforts, such as changes in the municipal solid waste market and different waste processes of their disposal. Additionally, some methods—such as thermal treatment—which seemed to be not fully aligned with the circular economy approach have advantages not taken into account before. Incineration of higher volume of waste affects the waste structure and will change some of the circular economy objectives. The analysis was carried out on the example of the Polish market.

Local governments face the need to achieve sustainability in the provision of public services, and to do so, proper governance is essential. This work proposes a method to assess governance in local waste management systems based on a set of indicators that are flexible and robust enough to allow objective and reliable evaluation even where the information that is available is deficient. The proposal is based on a set of indicators divided into six categories that represent an increasing order of governance maturity: institutional framework; government effectiveness; transparency and accountability; network creation; participation; and corruption control. The article presents the proposal and a first test in two Mexican municipalities, which are an example of municipal solid waste management systems in an incipient stage of development, where there may be serious limitations in terms of access to information. The results show that the methodology can be replicated in different contexts and can be useful for making decisions about improvements in municipal solid waste management systems or for comparing them with others. In addition, sufficient information was obtained for a first diagnosis of the cases studied, which indicates the coherence of the proposed framework. Points for practitioners Proper governance is essential to achieve sustainability in the provision of public services. The assessment of local governance must be robust enough to motivate changes and, at the same time, flexible enough to allow reliable evaluation where the quality of service and the availability of information may be scant. We propose a new framework for the assessment of governance in municipal solid waste management systems that meets these requirements, based on a set of indicators clustered according to governance maturity.
