Abstract Hotel XYZ is a commercial area in the city of Bandung which still applies the traditional linear economic cycle. The 61.61% of ±9000 m2 building area is used for room service facilities. The hotel has not paid attention to its waste management so all the waste generated from this hotel end up at the landfill area. This study aims at improving the waste management in Hotel XYZ to meet the principle of circular economy. Using SNI 19-3964-1994 approach to measure the generation of waste composition, the amount of waste generated from room service facilities is 0.03 kg/m2/day or 0.41 liter/m2/day. The zero waste index (ZWI) calculation was used for the evaluation of waste management in the hotel. The waste generated at Hotel XYZ has the potential to achieve substitute material savings by 63.16 kg, substitution of energy by 775.79 MegaJoule (MJ), greenhouse gas (GHG) reduction by 49.36 kg/CO2e, -164.06 L/kg of water saving. The most waste generated by hotel room service facilities is recyclable waste consisting of single-use packaging from hotel equipments. Waste reduction plan for the room service facilities is carried out by replacing single-use packaging with refillable packaging so the hotel is able to save their shopping expenditure costs up to Rp. 844,691.00 per day.

<p>Waste management in the Dasan Agung Market in Mataram City still uses conventional patterns. This pattern is not in line with the NTB Province policy that launched the concept of zero waste in 2019-2023. One approach that can support the program is the 3R method of waste management. This study aims to develop a waste management plan using the 3R approach. The method used in this study is the observation method, which is observing the current conditions and measuring the generation and composition of waste. The technique of determining the sample and measurement time and the procedure refers to SNI-19-3964-1995. The results showed that the amount of solid waste generation in Dasan Agung Market was 2.7 m<sup>3</sup> / day and the weight of solid waste was 467 kg / day. Waste composition was obtained by organic waste 52.60% and inorganic waste 47.40%. TPS 3R is planned with an area of 110 m<sup>2</sup>, namely 74 m<sup>2</sup> for composting area and 36 m<sup>2</sup> for sorting and handling inorganic waste, and residual waste. The composting system implemented is using the drum method with a capacity of 100 liters, a total of 307 pieces.

The World

People around the world generate billion tons of waste. Over two billion tons of solid waste was produced in 2016 and it is estimated to rise to 3.4 billion tons by 2050. The world’s trash amount is reaching crisis and seems to getting bigger and bigger unless we take a systematic action to deal with it. The purpose of this article is to study a methodology for zero waste municipalities, examine the role of a community in addressing municipal waste and moving towards zero waste, and to evaluate how circular economy can contribute in achieving zero waste municipality. Zero waste is likely adopted as a mechanism for waste management, but circular economy is a mechanism for industries and businesses in both eliminating waste and promoting resource efficiency as products are intentionally designed and manufactured to be repurposed and recycled. The result showed that with the circular economy concept, the waste can be reduced at the first stage of prevention as products are designed to use regenerative materials and designing technic to make them last longer and repairable in the light of designing out waste. Also, waste can be getting less and less due to the practices of reuse and repair service which extends product life cycle. Recycling is another practice that contributes to waste elimination as the component parts and materials will be used for manufacturing new products.

Household Emissions

In this chapter, the authors conduct original research on household emissions based on data from various sources in the literature. They analyze the extent of reduction of GHG emissions by adopting zero waste strategies by the households voluntarily, incurring no costs, but rather savings in wasteful expenditure. They then model this extent of reductions using a global computable general equilibrium (CGE) model to understand what could have been the carbon tax imposed to achieve this extent of GHG reduction. From the analysis, they find about 50% of GHG potential can be reduced from household emissions, as well as the associated life cycle emissions of products consumed. Reduced wasteful expenditure may facilitate both savings-led investments and the purchase of more green products by consumers, thereby boosting the economy. Therefore, they conclude that policies that incentivize zero waste lifestyle may go a long way in reducing the supposed tradeoff between the economy and the environment. They also review some strategies for the households, based on the literature, to minimize waste.

Waste Management Practices

Zero waste has an important position in the circular economy model in terms of manufacturing recyclable products instead of products to be consumed quickly, reducing the amount of waste, developing and implementing recycling/reuse technologies, and thus ensuring resource efficiency. A zero-waste strategy is one of the basic steps to achieve the goal of the circular economy. The number of studies conducted on Turkey’s zero waste management strategies referring to the circular economy is quite limited. To fill this gap in the literature, this study aims to identify the potential barriers which have an important role in zero waste management practices in Turkey. Through a broad literature review and expert opinions, 12 key barriers for zero waste implementation in Turkey have been defined in view of circular economy principles. Then, fuzzy DEMATEL methodology is employed to examine which is the most influential barrier affecting zero waste management success and to identify the interdependence of these barriers. The results indicate that uncertainty of the goals and tactics relevant to the circular economy and lack of financial and economic aid are key causal barriers that affect Turkey’s zero waste management.

Legislative Review

Plastic has been present in our lives for the past century as an essential material for many commodity items. However, the same properties that make plastic convenient are also responsible for the current dramatic environmental pollution. As an alternative, most of the world has been working with technological innovations, and one of its strategies is the use of bioplastics. Despite being considered environmentally beneficial by some people, there are still developments and discussions that need to be made. This article aims to present a legislative review and discusses the difficulty in implementing policies related to the incentive of the bioplastics market, as well as presenting some state and municipal laws, already prohibiting single-use plastics in Brazil. These laws aim to encourage the substitution of these plastics for biodegradable ones. However, it still has gaps and a lack of clarification on how the banning of disposable plastics and their substitution will be beneficial since composting is still an incipient process in the country. It is also the purpose of this article to discuss the challenges in the context of the Circular Economy, as well as the potential solution based on the creation of public policies aimed at improving waste management, in addition to clearer legislation on alternatives to single-use plastics.

Abstract SMAN 14 is one of the educational institutions that still adhere to waste management with a liner system, namely waste generated and disposed of in the final disposal site. In addition, SMAN 14 Bandung is a school with the title of an independent Adiwiyata School with environmental insight, but this school has not paid attention to managing its waste. This study aims to plan waste management with zero-waste approach so that the amount of waste sent to landfills is zero. Calculation of zero waste index (ZWI) was performed for a school scale wherein the results of ZWI were used for evaluation and as a basis for the future planning of solid waste management. Sampling measurements were carried out using the load count analysis method. The waste generated is 37,544 kg/day. With a composition of 13.12% organic, 60.42% plastic, 20.957% paper, 0.36 % metal, and a mixture of 5.14% with a zero-waste index of 0.80, the substitution of material savings of 30.09 kg, the substitution of energy 953.94 MJ, greenhouse effect reduction 26.89 Kg/CO2e, and water-saving -232.02 L. Furthermore, through this planning, the estimation of cost reduction was as much as Rp. 23,315 a day.

Abstract The World Bank reported that around 1.3 billion tonnes of municipal waste were generated in 2011, and this amount is expected to increase to 2.2 billion tonnes by 2025. Zero Waste Index (ZWI) is a breakthrough for measuring and evaluating waste management's performance based on the concept of zero waste, where recycling is the key to determining this value. This study was conducted in a province in a developing country, namely Bali Province, Indonesia. The calculation of ZWI and energy substitution from waste management is carried out on two schemes, an optimistic scheme (basic data and percentage of waste management targets referring to the regional policy and strategy documents) and a pessimistic scheme (basic data refers to material flow analysis of waste with no increase in the percentage of waste management) from 2020 to 2025. Energy substitution is calculated on two conditions of use, namely through incinerator technology (listed in Indonesia Presidential Regulation No. 35 of 2018) and without incinerators at the Sarbagita Regional Landfill. Analysis indicated that the pessimistic scheme provides a higher ZWI value of Bali Province in 2020 than the optimistic scheme, but there is no increase in the ZWI value until 2025 (the ZWI value ranges from 0.02 to 0.2) due to no increase in the percentage of solid waste management. Meanwhile, the optimistic scheme provides a lower ZWI value for Bali's Province in 2020 than the pessimistic scheme, but there is an increase in the ZWI value every year until 2025 (the ZWI value ranges from 0.004 to 0.22). In terms of energy substitution, an optimistic scheme provides energy substitution values ​​2-5 times greater than pessimistic schemes, with and without incinerators. However, in terms of the incinerator efficiency, the pessimistic scheme provides greater efficiency (2-6% efficiency when using an incinerator) than the optimistic scheme (1-2% efficiency when using an incinerator). The 3R (Reuse, Reduce, Recycle)-based waste management and high energy substitution potential in Bali Province can be an effective waste management solution if the stakeholders are committed to achieve the Jakstrada targets by 2025.
