Zero Waste is a strategy offering waste management solutions for today’s businesses. The Zero Waste strategy has been created with the objective of stimulating sustainable utilisation of resources, production and consumption with the highest possible level of recycling of generated waste. Due to the fact that currently there is very little information and only few relevant data available as a base for the implementation of the Zero Waste strategy, waste management specialists approach and apply such a strategy in different manners. On the other hand, there are areas of waste management where such a strategy has already been applied on a long-term basis in spite of non-existing relevant legislative tools. Indicators determined in the Zero Waste strategy may be achieved only if the individual countries clearly define legislative environment and adopt a national Zero Waste strategy with achievable objectives unambiguously determined. The area of waste separation, or handling of fractions of waste non-utilisable as secondary materials after separation, is one of the areas directly connected to the Zero Waste strategy. The objective of this paper is the evaluation of the usage of fractions of waste non-utilisable as secondary materials for energy recovery, providing thus valuable knowledge and information for the implementation of the Zero Waste strategy.

Secondary Carbon

Abstract Waste is a valuable secondary carbon resource. In the linear economy, it is predominantly landfilled or incinerated. These disposal routes not only lead to diverse climate, environmental and societal problems; they also represent a loss of carbon resources. In a circular carbon economy, waste is used as a secondary carbon feedstock to replace fossil resources for production. This contributes to environmental protection and resource conservation. It furthermore increases a nation’s independence from imported fossil energy sources. China is at the start of its transition from a linear to circular carbon economy. It can thus draw on waste management experiences of other economies and assess the opportunities for transference to support its development of ‘zero waste cities’. This paper has three main focuses. First is an assessment of drivers for China’s zero waste cities initiative and the approaches that have been implemented to combat its growing waste crisis. Second is a sharing of Germany’s experience—a forerunner in the implementation of the waste hierarchy (reduce–reuse–recycle–recover–landfill) with extensive experience in circular carbon technologies—in sustainable waste management. Last is an identification of transference opportunities for China’s zero waste cities. Specific transference opportunities identified range from measures to promote waste prevention, waste separation and waste reduction, generating additional value via mechanical recycling, implementing chemical recycling as a recycling option before energy recovery to extending energy recovery opportunities.

Slaughter House

Presently the slaughter houses of khulna city corporation (KCC) area in Bangladesh are being used in such a way that the wastes come from these are polluting the surrounding environment such as river water, solid surface, air etc. In this circumstance, the research analyzed the management options of this slaughter house wastes and determines how this process would be suitably managed through the community participation. To fulfill the above mentioned objective, the research work was conducted through the questionnaire survey, direct observation, face-to-face interview along with the random sample collection and relevant measures of different factors. The research finding reveals that the total quantity of waste produced from these slaughter houses was 2888.45 tonnes/year. The management of this volume of waste was found as unsatisfactory by the most of the stakeholder groups due to fail of the conservation of public health and ecosystem of the local community. However, the analysis of the research data and other relevant information suggest that the potential management system such as a zero waste management of the wastes of slaughter houses in Khulna City Corporation area is possible to implement for more environmentally friendly development of the society which have the potential to resource reuse (waste-to-energy recovery) and others. Finally, the research recommended three separate designs of the conventional biomethanation plant and a potential biogas production model for these slaughter houses.

Urban Footprint

Currently cities consume 60–80% of natural resources globally. They produce 50% of global waste and 75% of green-house gas emissions. The UN estimates that 66% of the world’s population will live in cities by 2050 while the global urban footprint will triple over the years to 2030. Thus cities, as a system of production and consumption, threaten the environmental sustainability of the globe. Looping actions—reuse, recycling and recovery of resources (materials, energy, water, land and infrastructure)—can help to address resource scarcity and wastage in cities. However, there are many challenges to implementation. Much of the literature explores the challenges to looping actions within resource sectors and for specific actions (i.e., challenges to adaptive reuse of buildings, recycling of material waste, energy recovery from sewage). It often does so without any clear reference to context. Nexus solutions are becoming a popular resource looping response to tackling wastage in cities. Some of the challenges to implementation have been explored, but influence of context has not been investigated. In this paper we explore the challenges facing the implementation of looping actions in cities. Using a mixed methods approach, we identify 58 challenges to looping actions across eight themes. We also establish the challenges to implementing a nexus solution. The research identifies five common implementation challenges. Addressing these challenges could enable looping actions across resource types in cities. The research also demonstrates how context affects the challenges to implementing looping actions and nexus solutions in cities. Nevertheless, the analysis suggests that there are some common levers for promoting looping actions and nexus solutions in cities, regardless of context.

Urban Waste Management

This article illustrates the result of a study based on the life-cycle costing technique applied to urban waste management in a typical Italian setting, in order to discuss the economic and ecological foundations of a management paradigm inspired by the "zero-waste" philosophy. We identify landfill availability as a critical natural capital requiring the adoption of strong sustainability indicators. We argue that the zero-waste approach is neither feasible nor desirable. Instead, strong arguments can be found in favour of a "zero-landfill" strategy, to be achieved through an adequate mix of material and energy recovery.

Environmental Savings

The current waste management system, handling around 500,000 t of household, commercial, and institutional waste annually in the Irkutsk region, Siberia, is based on landfilling in an old landfill with no controls of leachate and gas. Life-cycle assessment modelling of the current system shows that it is a major load on the environment, while the simulation of seven alternative systems results in large savings in many impact categories. With respect to climate change, it is estimated that a saving of about 1200 kg CO2 equivalents is possible per year, per inhabitant, which is a significant reduction in greenhouse gas emissions. The best alternatives involve efficient energy recovery from waste and recycling by source separation for commercial and institutional waste, the major waste type in the Irkutsk region. Recycling of household waste seems less attractive, and it is therefore recommended only to consider this option after experience has been gained with the commercial and institutional waste. Sensitivity analysis shows that recovery of energy – in particular electricity, heat, and steam – from waste is crucial to the environmental performance of the waste management system. This relates to the efficiencies of energy recovery as well as what the recovered energy substitutes, that is, the ‘dirtier’ the off-set energy, the higher the environmental savings for the waste management system. Since recovered energy may be utilised by only a few energy grids or industrial users, it is recommended to perform additional local assessments of the integration of the waste energy into existing systems and facilities.

Waste management is still defined as limited to collection, transportation and garbage disposal. The follow-up of the meaning is the provision of facilities such as garbage bins, garbage trucks and waste collection land. Waste management has not included waste separation. Segregation of waste can minimize the amount of waste that must be discharged to the final place. Segregation of waste can supply recyclable raw materials and handicrafts made from garbage. The manufacture of handicraft products from garbage is still local and requires socialization and training. It is needed to increase the number of craftsmen and garbage absorption on the crafters. Through careful socialization and training, citizens' awareness of waste management becomes advanced by making handicrafts of economic value from waste materials.
