“…Because the use of secondary material substitutes the production of virgin materials, less energy is consumed, indicating a negative economic impact. The implementation of WB can contribute to SDG 2,3,4,5,6,10,11,12,13,14,15,and 16 in the resource recovery phase. Meantime a contradiction in SDG 7, 8, and 9 and a weakening in SDG 1 are predicted.…”

“…Thirdly, almost all sustainability assessments in the field of waste management are at the product-level. Often, the sustainability impact of several technologies (e.g., energy recovery, material recycling, landfill gas utilization, and so on) are assessed and compared [13][14][15][16]. A city-scale assessment which considers the corresponding change induced by the technology is rarely conducted.…”

Various municipal solid waste management (MSWM) innovations have emerged in developing countries in face of the challenges posed by increasing waste generation and poor MSWM practice. We present a methodology to assess the potential sustainability impact of MSWM innovations in a holistic manner. The Life Cycle Sustainability Analysis (LCSA) framework and the United Nations (UN) sustainable development goals (SDGs) facilitated the methodology development. The result of applying the methodology to the case of waste bank (WB) in Bandung City shows that WB potentially generates the greatest sustainability impact in the resource recovery phase and the smallest impact in the collection and final disposal phase. All negative impacts could arise in the economic dimension. Surprisingly, WB as a national strategy to achieve 3Rs would not effectively solve Bandung City’s landfill problem. Almost all SDGs would benefit from the WB program under the assumed conditions. This methodology will facilitate the decision-making in MSWM by (1) comparing available innovations to find the optimal solution, (2) identifying the hot spots and taking measures to combat the negative impacts, (3) providing the basis for monitoring the implementation process and the ex-post performance assessment.

“…The results from the door-to-door program showed that the waste contamination issue was almost solved at only 1.5% of impurities. Moreover, the waste to landfills in 2010 was 53.8% less than that in 2009, about 80% of waste was diverted from landfills in 2012 [41,43], and average 28.6% of reduction in total produced waste [44]. Regarding the financial matter, Error!…”

Despite the increase in popularity of Zero Waste (ZW) concept, the successful implementation of this concept in waste management is still facing many challenges. The plastic recycling rate in Australia is currently only about 9.4%, which could leave up to 90.6% of plastic consumption being sent to landfills. The state of Victoria (in Australia) has proposed an ambitious plan to upgrade its waste and recycling system and to divert about 80% of waste from landfills by 2030. The aim of this research is to study Victoria’s current waste management plan and to develop a simulation model to assess the feasibility of it achieving zero plastic waste by 2035. In this direction, a fundamental knowledge of global ZW implementation needs to be acquired in order to understand the challenges, obstacles, and uncertainties in achieving ZW target. A simulation model is established using a method called double baselines. This method was developed as an improvisation to address the limitation of data availability for the model development. The model will run on 4 scenarios including one from Victoria’s current plan. Outcomes from the model are produced in comparative charts covering 6 key considerations including the rates of plastic consumption, waste to landfill, diversion, recycling, relative accumulative cost and effort. The findings of this study pointed out that Victoria’s current plan are feasible for its goal and presented with opportunities for improvement especially towards zero plastic waste. Besides, study results also reveal that the Victoria’s current plan to achieve 80% diversion rate by 2030 is possible but the zero plastic waste target by 2035 is less likely to happen.

“…Taiwan achieved a recycling rate of 58% in 2016, and the rate is expected to continue to increase (Taiwan EPA, 2017). Taiwan’s MSW recycling rate is higher than those of Malaysia (5.5% in 2014), Spain (17% in 2012), and Hong Kong (52% in 2013) (Bueno et al, 2015; Tan et al, 2014; Woon and Lo, 2013). The percentage of food waste increased from 4% in 2005 to 10% in 2011 and stayed about the same (~10%) thereafter.…”

Estimation of willingness-to-pay for the MSW disposal system by choice experiment approach: A case study of Taiwan

In Taiwan, municipal solid waste (MSW) is separated into general, recyclable, and food waste categories. General waste must be packaged into pre-paid trash bags before final disposal. Recyclable items and food waste are collected separately to reduce the costs of using pre-paid trash bags. This study applied a choice experiment approach to evaluate marginal willingness-to-pay (WTP) in different MSW disposal system scenarios. Variables include cleanliness, location for purchasing pre-paid trash bags, frequency of waste collection, and distance to waste disposal. The results indicate that cleanliness, location, and distance influence public behavior, acceptance, and participation. Higher collection frequency decreases public acceptance. Some of the socio-economic variables of the respondents, including age, education, and marriage status, affect MSW management alternatives. The marginal WTP of the scenarios in this study ranged from US$0.04-0.07 per trash bag. Online purchasing of pre-paid trash bags is more cost-effective and should be encouraged. The results of this study provide useful information for the development of policies related to waste management systems.
