Each year a large number of wooden pallets are manufactured, recycled, and disposed of during the transportation of goods throughout the United States. The production of these pallets consumes a significant amount of wood and a large number of pallets also end up in landfills at the end of their useful life cycle. However, these pallets can be recovered through repair, broken apart into components, ground into mulch, fuel, animal bedding, or used by landfills for day to day operations. The purpose of this research was to investigate the total number of pallets and crates reaching landfills in the United States as well as to gain a better understanding of the overall waste stream. This was done by surveying all licensed Municipal Solid Waste (MSW) and Construction and Demolition (CandD) landfills in the continental United States. A questionnaire was sent to these landfills, and this entire study was intended to build upon previous Virginia Tech landfill surveys conducted in 1995 and 1998 with some changes made after careful review. Overall, it was found the average MSW facility in the United States received 185,077 tons of waste and the average CandD facility received 74,911 tons. This results in a total national estimate of 253 million tons of MSW and 76.9 million tons of CandD waste. Approximately 18.3 million pallets were landfilled and an additional 13.8 million were recovered, repurposed, or reused at MSW facilities. At CandD facilities, approximately 19.2 million pallets were landfilled while 38.3 million were recovered. / Master of Science

In general, the improper disposal of waste may hinder the constitutional guarantee of a right to an environment to human health or well-being. This is especially true of domestic solid waste, a particular area of the waste stream frequently disposed of on South Africa's vacant land, rivers and streets amongst other. There is need therefore for municipalities as locally based authorities that are constitutionally bestowed with specific functions and duties in relation to waste, to ensure effective domestic solid waste management. The aim of this study is to investigate the content and design of some legal instruments aimed at domestic solid waste management in two municipalities of South Africa’s Limpopo Province namely the Lephalale and Greater Tzaneen Municipalities. The investigation and critical analysis of the selected instruments are based on the content of South Africa’s national waste law and policy with respect to domestic solid waste management specifically. The study concludes with a number of observations and recommendations with respect to the investigation instrumentation of Lephalale and Greater Tzaneen Municipalities. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014

In 2005, the Recycling Council of Ontario published a report that identified the construction industry as one sector that did not manage its waste in an environmentally appropriate manner. In this report, Let’s Climb Another Molehill, 15 case studies were executed to understand why this industry was neither handling nor disposing its waste properly in Southern Ontario. A set of generic recommendations was generated to help improve the management of this industry’s waste. Unfortunately the scope of the report was too broad to support conclusions about the management of specific types of problematic construction waste. The aim of this thesis is to narrow what was done in Let’s Climb Another Molehill to focus only on gypsum wallboard. The purpose of this research is to determine what options are the most desirable and feasible to deal sustainably with gypsum wallboard waste in Southern Ontario, both now and in the future. All recommendations offered are case specific. A number of methods have been utilized to obtain the information needed to formulate appropriate recommendations to deal with wallboard. Information learned through the literature, witnessed through the observation sessions, and acquired through the interviews led to two unique option categories: 1) alternative materials and 2) change in practices. To evaluate these options, a set of criteria was created based on the concepts of sustainability and integrated waste management (IWM). This sustainable IWM criteria set allowed for consistent evaluation of the options. To improve the recommendations, the sustainable IWM criteria were refined to better deal with each of the two categories of options. When the sustainable IWM criteria for evaluating alternative materials were applied, gypsum wallboard was found still to be the best interior wall material to use today. However, applying the sustainable IWM criteria for evaluating change in practices showed that the problem with using this product lies with its management and, therefore, the remaining recommendations focus on improving the creation, use and disposal of wallboard. Many of these recommendations can easily be adopted to help eliminate inappropriate wallboard management practices. This research was able to identify areas where problems arose and to offer feasible options to improve environmentally inappropriate behaviors associated with wallboard management. Although numerous recommendations are offered, the three fundamental recommendations that will lead to the biggest change include: 1) greater number of educational programs devoted to the construction industry; 2) stricter regulations and better enforcement; and 3) a dramatic increase in landfill tipping fees. If these three recommendations were implemented, it is believed that they will play a positive role in managing gypsum wallboard waste in a more sustainable manner.

A fast increase of municipal solid waste (MSW) has become the most concerning environmental problem in Vietnam, especially in the Mekong Delta region, that is considered one of the most vulnerable deltas to climate change in the world. There are 12 provinces and one central city in MD that occupy about 12% of the whole area of the nation with 5% of MSW generated. However, there is no currently effective management system in place for treatment and management of MSW in the MD. Landfill is the sole treatment option for MSW right now. With a low-level plain, MD is facing the most serious environmental problem in the near future with an effect of climate change and sea level rising. The landfill should not be considered for long-term use in this area. Suitable treatment options for MSW should be applied together with other solutions for reuse, recycling and reduction of MSW as well as pollution prevention issue. An integrated MSW management approach in adaptation to climate change is considered necessary. / Sự tăng nhanh chất thải rắn đã trở thành vấn đề vấn đề môi trường được quan tâm nhất ở Việt Nam, đặc biệt là ở khu Đồng bằng Sông Cửu Long một trong những đồng bằng dễ bị tổn thương bởi sự biến đổi khí hậu nhất trên thế giới. Đồng bằng Sông Cửu Long có 12 tỉnh và một thành phố trực thuộc trung ương, chiếm 12% diện tích của cả nước với khoảng 5% lượng chất thải rắn phát sinh. Tuy nhiên, hiện nay chưa có một hệ thống quản lý hiệu quả cho chất thải rắn ở khu vực. Bãi rác là lựa chọn xử lý duy nhất ở thời điểm này. Với cao độ thấp, Đồng bằng Sông Cửu Long đang đối mặt với ảnh hưởng nghiêm trọng của các vấn đề môi trường trong tương lai gần bởi ảnh hưởng của sự biến đổi khí hậu và nước biển dâng. Về lâu dài bãi rác không nên sử dụng ở khu vực này. Các lựa chọn xử lý thích hợp cho chất thải rắn cần được áp dụng cùng với các giải pháp khác như tái sử dụng, tái chế và giảm thiểu chất thải rắn cũng như các giải pháp ngăn ngừa ô nhiễm. Cách tiếp cận quản lý tổng hợp chất thải rắn nhằm ứng phó sự biến đổi khí hậu cần được xem xét.

The Kingdom of Saudi Arabia is the largest country in the golf states and one of the richest oil producing countries. Saudi population is nearly 27million; in addition, Saudi Arabia receives millions of people from around the world for Islamic pilgrimages. Moreover, Saudi is hosting hundreds of thousands of international professionals and labourers. Hence, the country infrastructure and services have been in the top agenda to be modernized in order to cope with new demand for better quality of life for a rich country. The healthcare sector is one of the key sectors which requires a special on going attention, particularly medically generated waste. Therefore, this research work has been conducted to investigate the status of medical waste management in the capital city; Riyadh. The prime aim of this research work is to propose a strategic framework which can be used as a roadmap for the different stakeholders. This will contribute to the enforcement of better handling and treatment of medical waste and more importantly prevent and control the spread of diseases or harm might be caused by poor handling of medical waste. The aim of the research has been achieved through; the critical review and analysis of the relevant literature, which has revealed the noticeable gap and lack of scientific studies of the proposed field. Appropriately, the findings of the research has contributed to filling the gap of the knowledge as well as serving as a milestone for further research work in this very important field. By surveying Riyadh’s hospitals and other national and international reports has. This allowed the presentation of the facts and indications of the current status of medical waste in Riyadh City. To obtain in-depth knowledge and gather the important findings concerning the medical waste management, focused; interviews of different medical professionals from various hospitals were conducted. This research has revealed more important factors that need to be addressed. These findings were used to propose the framework, which has been formed to enable resolving the challenges of the integration, of the awareness element though Islamic principles, within the Saudi system. The proposed framework has been evaluated by committee of medical professionals and has been accepted as good roadmap and appropriate solution that address the main aim of this research work. Finally, the research work is just a step towards the establishment of a proper biomedical waste management system in the Kingdom of Saudi Arabia. Some recommendations for future implementation are suggested at the end of this thesis.
