Waste Accumulation

The issue of waste accumulation has become one of the global problems of humanity. In Ukraine, the main method of waste management is landfill depositing, which is unproductive and affects the ecosystem negatively. However, large landfill sites should be used to produce biogas, thereby reducing the environmental burden and the earned revenue should be used to introduce recycling and a gradual transition to a European waste management policy. The aim of our study was to investigate the state of waste recycling and the possibility of using waste landfills and food with lost consumptive qualities for biogas generation. To analyze the economic efficiency of the installation of biogas equipment in landfills and to investigate the current state of waste management in Ukraine. The research demonstrates that at present in Ukraine the problem of waste accumulation becomes actual. At the same time, the number of large waste landfills is increasing. It is proved that at landfills with an area of more than 50 hectares, the installation of biogas equipment is cost-effective, and the raw material can be distributed at the feed-in tariff, thus solving the energy problem.

Abstract Among the most urgent topics within waste management policy is the gradual transition of the economy from a linear model towards a circular economy with a more sustainable way of using resources. The European Union has responded to these changes by passing new legislation and ambitious targets so that all member states can quickly work towards achieving a greener and more sustainable Europe. However, the starting position for achieving the desired goals differs significantly from one country to another. In this paper, we therefore looked at the position of Slovakia in relation to selected waste management indicators, and at the measures taken so far. Moreover, since waste management falls under one of the many public benefit services provided under the remit of local governments, we also monitored the specific contribution of Slovak cities to the newly established trend of waste management in the country.

Waste generation in India has been increasing, and there are no adequate ground implemented policies for the safe disposal of waste. It increases land and water pollution. Some industries execute zero waste management at their level, but that is not enough to reduce the load on the city's main landfill and disposal site. It is the need of the hour to implement the micromanagement of waste. There are large numbers of schools and colleges in India which generate the same type of waste. These campuses can demonstrate and influence the students, faculties, and other staff and visitors to adopt and successfully implement sustainable practices. Schools and colleges can play an essential role in changing society by teaching students about the new waste management technologies. There are numerous opportunities to introduce new technologies into waste management. The challenge is to encourage the development of technologies that are most conservative of natural resources and that are cost-effective. This paper shows the zero waste management policy in Campus of Techno India NJR Institute of Technology, Udaipur. Separation of waste at source is a vital and essential part of zero waste management. Biodegradable waste is used for composting, and plastic is used for brick manufacturing, a college start-up project. E-waste and hazardous waste are handed over separately to authorized recycling firms.

Waste Management Policy

Municipal solid waste management is an environmental issue that has received considerable attention from researchers and environmental managers for decades. Supporting the management programs entail policies and regulations related to municipal solid waste. In developed countries, the implementation of environmental policies plays an important role and has a substantial impact on the effectiveness of solid waste management. However, in many developing countries such as Vietnam, the situation and effectiveness of the policy implementation have not been studied extensively. This investigation is conducted to ascertain the situation, limitations, and challenges in implementing solid waste management policy in Vietnam. Then, solutions for the problems and improvements for implementation efficiency are presented. This work used online questionnaires to survey environmental managers in different localities and applied qualitative research method to analyze data. The results show that not all national policies on solid waste management are implemented in all localities. Waste separation is also the foremost concern in municipal waste management in most localities of Vietnam. Most of the localities claimed that the unrealistic nature and difficult implementation of the policies and the lack of needed resources are the main limitations and challenges in Vietnam. Survey results also revealed that different localities in Vietnam have different solutions to increase policy implementation efficiency. Besides, the study also found similarities in the implementation of policies in solid waste management between Vietnam and some other countries and also gathered some valuable lessons for the improvement strategy. Finally, the implementation of an effective domestic solid waste management policy is an important platform for improving environmental quality and ensuring the sustainable development of the nation and mankind.

An effective waste management system is, and has always been, essential infrastructure, particularly given the potential for waste to adversely impact the surrounding environment. In recent decades, however, there has been growing awareness of the scale, breadth and immediacy of those adverse impacts, and of the unsustainability of the enormous (and increasing) amount of waste society generates. Governments around the world have mobilised and there has been a widespread shift towards policies promoting circular economies, waste minimisation and maximised resource efficiency. Singapore is a case in point; despite having a traditionally high waste output and a waste management system dependent on waste incineration as the primary means of disposal, Singapore has committed to a zero waste future. This article presents a review of domestic waste management policy and law in Singapore. Several gaps in the legal framework are identified and considered against the broader context, leading to the conclusion that there is a material environmental vulnerability in the legal framework that should be redressed in order to entrench environmental protections and to align the law with Singapore's policy ambitions. Notwithstanding this deficiency, it is hard not to be optimistic about the future of domestic waste management in Singapore, as the government has made an ambitious policy commitment and appears to be pursuing it with vigour.

In this work, the properties of the composite produced from waste carton with various tiger nut fibre contents having cassava starch slurry as binder were investigated. The results obtained showed the ranges of the mean thermal conductivity, bulk density, specific heat capacity, thermal diffusivity, thermal absorptivity, nailability, flexural strength  and compressive strength values to be (0.0447 – 0.0603) Wm-1K-1, (683.62 – 746.32) kgm-3, (1439.811 – 1840.554) J/kg/K, (5.612 - 3.553) 10-8 m2s-1, (25.456 – 31.993) m-1, (23.9 – 100)%, (1.58 – 1.86) MPa and (2.16 – 2.78) MPa respectively between  8.3% and 43.1% of the fibre content.  It was generally observed that with a choice variation in the fibre content, the performance of the developed board can be optimized for structural applications. Hence, instead of discarding the fibre as waste, recycling it can help to provide raw material for the production of cost effective and environmentally friendly materials. This will in turn reduce health risk caused by environmental pollution due to improper waste disposal practice of such material.

Abstract Following Tantawan field suspension of production, considerable volume of contaminated crude (high level of mercury and arsenic content) remains on board in Tantawan FPSO. These volumes are deemed as waste hydrocarbon sludge that hold no commercial value and must be urgently removed from the vessel as per safety requirements to maintain the vessel class and certification, according to Tantawan FPSO integrity condition. After review of many alternatives, offshore subsurface disposal initiative is the safest and most cost-effective means for disposal. Since subsurface disposal of such waste, highly mercury and arsenic contaminated crude, has never been performed in the Gulf of Thailand, several aspects need to be considered from technical and environmental perspective and public sector concerns. A cross functional team of Reservoir Engineer, Geologist, Facilities Engineer, Health and Safety, Policy, Government and Public Affair and commercial advisor, has co-devised a holistic waste management plan to inject waste into Tantawan reservoirs after obtaining required approvals by the government. Many challenges including limitation of the FPSO pumping system, sludge properties and seasonal increment weather, were encountered during the execution phase and many remedial actions were taken to mitigate their impact. Cross functional team initiatives on heater installation, adjusting injection procedure, and additional disposal well approval helped address project challenges. Entire volume of sludge was safely injected to subsurface reservoirs with cost effective operation. The success of this offshore injection process has reduced the cost to less than 10% compared to onshore disposal option to asset joint venture. The results set a new standard for Thailand petroleum waste management policy. Following this success, decommissioning of all remaining of Tantawan field are progressing as scheduled. This paper will outline the holistic approach of hydrocarbon sludge management process including the subsurface injection identifcation, stakeholder engagement, environmental impact assessment and execution challenges. Lessons learned from this paper would help other offshore operators to effectively manage hydrocarbon sludge, which demonstrate how the oil and gas industry plays a vital role in protecting the environment.
