“…Greenhouse gas emissions and potential energy recovery have been studied as key factors to allow local authorities to draw up efficient MSW management plans [19]. For the implementation of the 'Industry 4.0' paradigms [20,21], different tools and technologies have been largely adopted to reduce greenhouse gases emissions and improve economic viability [22]. Moreover, the collection and transport of waste have been analysed in order to evaluate their consequences on public health, costs, depletion of resources, gas emissions and waste handling [23].…”

A Door-to-Door Waste Collection System Case Study: A Survey on its Sustainability and Effectiveness

Municipal waste management is a relevant topic these days, in its relation to sustainable and environmental concerns. Sorting waste fractions at home for a door-to-door collection system proves to positively affect the environmental impacts of waste management strategies both by reducing the amounts of the waste landfilled and by originating new circular economies. However, the environmental impact caused by both waste collection and transport, together with waste quality, should be carefully evaluated to assess the sustainability of such a collection system. In order to evaluate the logistic and environmental effectiveness of a newly implemented door-to-door collection system in Altamura, a mid-sized town in Southern Italy, a survey was designed and submitted to a sample of citizens. The results obtained from the 385 completed surveys show that the door-to-door collection of glass waste is inefficient since most of the designated bins remain partially filled and less frequently delivered; citizens are more motivated to adequately collect sorted waste fractions upon receiving information about the subsequent environmental benefits and outcomes of the fractions collected; a high percentage of people still use disposable items in their daily life. Possible changes to the weekly bins collection schedule have been proposed in order to have a more proficient and environmentally sustainable waste collection service in the town. The survey is part of a project aiming at developing a smart device to support users in home waste management.

“…In 2018, 29.5 Mt of waste was incinerated in the U.S. to yield 14 billion KW of electricity; 1 Mt of waste incinerated can yield 48 KW of electricity [11]. However, incineration can potentially generate significant GHG emissions; for 1 tonne of waste incinerated 1381.4 kg of CO 2 , 14.9 kg CO 2 -e of N 2 O and 0.15 kg CO 2 -e of CH 4 can be produced [12].…”

“…However, the potential for large quantities of methane to be produced and emitted in poorly aerated conditions during composting remains a challenge, especially in home composting systems [7] (Table 2). Composting can release up to 100 kg CO 2 -e of CH 4 and 71.52 kg CO 2 -e of N 2 O per tonne of waste [12]. Composting may also become inappropriate in densely populated urban areas due to hygienic concerns and the need for constant monitoring to prevent the emission of GHG [7] (Table 2).…”

“…The indirect way to reduce GHG emissions would be to utilise biogas synthesised from AD plants to generate electricity instead of fuel combustion. While the current status of AD technology in Australia might not allow for biogas [12] to substantially replace coal, crude oil and natural gas to generate electricity, the use of biogas where possible would contribute to GHG savings. The use of biofuel such as methane for transportation can further contribute to GHG savings.…”

Anaerobic digestion technology provides a new approach to treat organic waste while generating greenhouse gas (GHG) savings. Moreover, the methane gas produced during the process can be used to generate electricity. In order to ensure that Australia stays on its trajectory towards a carbon neutral future, the use of anaerobic digestion technology to treat its abundant organic waste streams should be considered. Thirty million tonnes (Mt) of organic waste was produced in 2017. The use of anaerobic digestion to treat 1 tonne of waste could result in 0.143 tonne of CO 2-e in GHG savings. In contrast, other more widely employed waste disposal methods such as landfilling, composting and incineration may generate GHG emissions. Additionally, the use of methane for electricity production also generates the least GHG emissions per MWh. This is approximately 3 times lower than crude oil, 4 times lower than black coal and 5 times lower than brown coal. However, the adoption and implementation of anaerobic digestion technology in Australia face several immediate constraints. Firstly, anaerobic digestion technology is deemed unprofitable, incurring high initial capital cost, operating costs and extremely long payback periods. Secondly, there is a lack of government support in terms of a national target for biogas production via anaerobic digestion. This review will provide an in-depth analysis into the current state of the Australian biogas sector. In addition, the review discusses the opportunities to make anaerobic digestion technology more financially viable and to accelerate the growth of the Australian biogas sector.

Introduction: e Covid19 virus has an outer lipid sheath that is not tolerant towards disinfectants, but this virus can quickly infect humans with a fairly high mortality rate. The increasing Covid19 patients directly proportional the amount of solid medical waste production in hospitals. This study aims to identify the health protocol in solid medical waste management in one of the Covid19 patient referral hospitals in Surabaya, East Java. Method: We used descriptive observational research with secondary data for the data compiling method. The obtained data were then compared with the 2020 Guidebook on Waste Management in Referral Hospitals, Emergency Hospitals, and Public Health Centers that Handles Covid19 Patients, issued by the Ministry of Health of the Republic of Indonesia. Result and Discussion: Research results showed that the management of all solid medical waste yielded from the Covid19 Special Isolation Room is directly infectious, went through the incineration process using an incinerator with the primary burner set at 800o C and the secondary burner set at minus 1.000o C. The usage of Personal Protective Equipment (PPE) by medical waste trolley carriers was inappropriate. The officers only used surgical masks, head caps, gloves, shirt, and work shoes, without using any apron. Conclusion: Health protocol for medical waste management in one of the Covid19 patient referral hospitals in Surabaya, East Java has been implemented, but the usage of PPE by medical waste trolley carriers was still inappropriate.
