Implementation Of Waste Management Research Articles

Decision support for selection of food waste technologies at military installations

The selection of an appropriate technology for waste management in a way that enhances sustainability is a complex problem requiring information from multiple disciplines. This decision is made more complex for large, diverse organizations for which individual sites or components have different requirements and capacities for waste management. For U.S. Army installations, sustainable waste management is a major obstacle for resource constrained and overburdened installation personnel. The Army has prioritized landfill diversion at installations; there is a significant push for each installation to develop and implement waste management plans that follow high-level goals set by U.S. Army Installation Management Command (IMCOM). The main objective of this study is to demonstrate an excel-based dashboard tool incorporating Multi-Criteria Decision Analysis (MCDA) for site-specific waste management technology selection. The dashboard uses the preferences of an installation and a series of weighted metrics to evaluate technologies. With this information the dashboard can rank the technologies to identify those that simultaneously meet IMCOM's objectives and are appropriate for specific sites' capabilities and resources. Fourteen different technology makes and models were compared in this version of the decision model including dehydrators, pulpers, garbage disposals, containerized in-vessel composting, windrow composting, forced-air static composting, and containerized anaerobic digestion. MCDA provides for transparent comparison of technologies for all sites, and the dashboard visualizes the level of appropriateness of each technology for each site. The approach developed here adds value in that it utilizes the priorities of the organization and identifies the best performing waste management technology given the specific capacity and capabilities of an individual site.

Attitudes towards recycling on construction sites

Waste management is a major area of concern for construction industries around the world. As the general public becomes more environmentally aware, waste management policies need to be evaluated with a view to making them more effective. With the number of environmental friendly construction projects on the increase, this study examines the attitude towards recycling on construction projects in contextual and applicational issues within Toronto, Canada. A number of theoretical factors causing waste and restricting construction projects from recycling are examined, and the current state of the Toronto construction industry is investigated by conducting a questionnaire survey of key personnel working in the field of construction project management. The aim is to determine what restricts construction sites from recycling and what would create incentives for this to become a more popular practice. The study found that compared with construction industries in other parts of the world, the Toronto construction industry is doing relatively well in terms of recycling and waste management. This paper can provide references for effective implementation of waste management in construction.

The Effectiveness of Health-Community-Based Waste Management in Yogyakarta

Integrated waste management framework: a business case from hospitality industry

Environment sustainability in tourism industry is an upcoming area of research that can benefit from integrated approach to waste management. Recent developments in waste management of hospitality sector have experimented with different methods, but less attention has been paid to integrate it as a strategic opportunity in the greening of services. Also, literature from the developing world have contributed with prescriptive and empirical studies on environmental performance of organisations, but limited on-the-ground kind of studies to explore the practical and contextual aspects of implementing waste management as a part of organisational process. This research article is based on a case study conducted in two co-located Ecotel ® certified hotels in India and examines the role of waste management as a business strategy. The study has used inputs from extant literature and learning from the case study to propose integrated waste management framework as a business strategy and to shift it stand-alone backend practice, which can help the firms from hospitality sector develop waste management as a part of its competitive differentiator.

In the present scenario, society has been increasingly concerned with the environmental issue. Research institutions produce a large portion of waste due to their routine activities. Thus, due to the important role research plays in our society, and the environmental impact that residues may present, it is necessary to implement waste management programs in these educational and research institutions. Given the above, this paper makes a diagnosis about the sources of waste generated at UPEA / IFF, and suggestions regarding proper treatment and disposal of it residues aiming future implementation of an environmental education program.

Waste Management of Fast Food Chains in Ozamiz City

Food chains are among the fastest growing business today. However, the large amount of wastes generated by these establishments threatened the environment and the health condition of the society they serve. This study determined the waste management practices adopted by selected fast food chains in Ozamiz City. Problems encountered in implementing waste management procedures were also identified. A cross-sectional survey was conducted using a structured questionnaire which passed the Chronbach’s alpha reliability test. Results revealed that more than 50% of fast food chains complied the waste management practices with wastes segregation (98.3%) as the most practiced. However, problems with adherence towards efficient waste management activities still exist. Collection (ranked 1), and segregation (ranked 2) of wastes were the problems identified by 41.7% and 35.0% of the respondents respectively. The results imply that the city wastes’ collectors and the staff responsible for wastes segregation need thorough knowledge of the significance of efficient wastes disposal practices.

More inclusive and cleaner cities with waste management co-production: Insights from participatory epistemologies and methods

With over half of the world's population living in cities, and with rising consumption, the generation of solid waste has become a ubiquitous and serious problem in urban agglomerations. City administrations are facing social, cultural, environmental, and economic challenges when planning solid waste solutions. The paper discusses the participatory epistemology and methodology experience resulting from inclusive solid waste management in Brazil. In the global South countless informal and organized solid waste collectors are engaged in resource recovery, classification of discarded waste, and redirection of recyclables towards the recycling sector. Their work is mostly unrecognized and the service is not remunerated. Governmental support to include recycling cooperatives in selective waste collection varies significantly in scope and quality. In theory, the Brazilian solid waste management legislation supports recycling cooperatives and promotes avoidance, reuse, and recycling as a primary solution tackling waste. In praxis, however, many challenges towards inclusive resource recovery and awareness building about waste avoidance and diversion are yet to be overcome. Action-oriented, participatory qualitative research, conducted with recycling cooperatives and local governments in the metropolitan region of São Paulo, has revealed some of the environmental and social contributions, as well as challenges arising in planning, policy design, and implementation of waste management. The research applies a feminist and post-colonial theoretical lense and demonstrates a wealth of knowledge co-generation on waste management. The participatory method underlines important social aspects to consider in planning and policy design for inclusive waste management. The final conclusion of this paper is that selective household waste collection with recycling cooperatives creates unique opportunities to build more inclusive and cleaner cities.

A Rubik's Cube Dilemma? The Implementation of European Union Waste-Management Policy in Ireland

Ireland's engagement with European Union (EU) waste-management policy has been characterized by low issue salience and an ambiguous response from the public administration system which tolerated weak regulation despite the introduction of the waste framework directive in 1975. Ireland's serial non-compliance with EU legislation eventually culminated in a significant 2005 judgement from the Court of Justice of the EU in Case 494/01 which referred to a systematic failure in the application of waste rules. This forced the Irish authorities to address the fragmented nature of waste-management implementation and adopt a more effective and coordinated enforcement system. Against this backdrop Ireland's efforts to translate EU environmental directives into action are explored through the case of the Landfill Directive 99/31/EC. Top-down and bottom-up perspectives from implementation theory are used to interpret how public administration has adapted to the challenges of formal and practical implementation. This is complemented by empirical findings drawn from a survey and interviews with officials and waste-management stakeholders. It is argued that while Ireland's performance in waste management has improved, its progress to meet the targets of the directive has been frustrated by the structural shortcomings in the design of an appropriate implementation structure.

Green Funds & Green Investing: A New Route to Green India

If you are looking to invest some money in stocks, are environmentally conscious and are frustrated with the way big corporations pollute environment, then green mutual funds may be for you. Despite being among the most recent types of funds in the market, these mutual funds have gained in popularity among many investors, for the past few years. Green funds are managed by companies which invest in corporations committed to the environment. Some of these corporations either implement clean energy practices or good waste management techniques. Then there are those which make recycled products or promote renewal energy. And some of them set aside resources to clean the environment. These are corporations which, while increasing their bottom line and making profit, do their bit for the environment too. Apart from the 'feel good factor' that you are helping to keep this planet clean and are a socially responsible citizen, you can also gain financially by investing in these funds. In the past there were very few companies that could have been called environment friendly. However, with several countries pledging their support for the environment and making environment friendly policies, several companies have come forward with a definite objective of being sensitive to the environment and reduce emissions. Indian mutual funds have not really shown much action in the green fund space through their global counter parts are active in the sector.In this context, this paper is intends to draw attention of mutual fund organizations towards green mutual funds, which are helpful for safe-environment and protection to earth. This paper focuses on various green funds, green investing companies and green funds mutual funds in India. Here, green India refers to pollution free India.

Development of a social impact assessment methodology for recycling systems in low-income countries

Informal recycling is one of the most significant activities within waste management systems in low-income countries. The main aspect of a number of recently implemented waste management systems has been to organise the informal recycling sector. The implementation of formalisation is expected to eliminate social problems related to the informal sector, but this has not been precisely measured and evaluated. A lack of methodology to assess social impacts persists, as does the comparison of different formalisation approaches. The goal of this work is to develop a methodological procedure for assessing the contribution of formalised recycling systems in low-income countries in terms of social impacts, in comparison with informal systems. Some existing social assessment approaches were evaluated by a review of literature. This investigation focuses on the development of the social life cycle assessment approach, the analysed social aspects, proposed indicators and characterisation models within this framework. This study proposes an approach for the social assessment of recycling systems based on formalisation approaches in low-income countries oriented towards the social life cycle assessment methodology (sLCA). The approach developed considers 3 social impact categories, 9 social subcategories and 26 semi-quantitative indicators for the assessment of the social impacts on formalised recyclers. It includes a characterisation procedure that takes into consideration the application of a score system and the calculation of average scores at both the indicator and subcategory levels. This research shows that it would be feasible to apply a sLCA-based methodology to evaluate recycling systems based on formalisation of the informal sector. The impact categories and subcategories identified represent the social problems of informal recyclers. The 26 semi-quantitative indicators and the proposed characterisation approach attempt to measure the social impacts that currently are only qualitatively assumed. The applicability and validation of the indicators and characterisation procedure will be determined by further research. The methodology developed will be tested using data from three recycling systems in Peruvian cities.

ANALYSIS OF A MUNICIPAL LANDFILL DRAINAGE LAYER USING TYRE SHREDS AND RUBBLE / SĄVARTYNO DRENAŽO SLUOKSNIO UŽSIKIMŠIMO TYRIMAS NAUDOJANT SMULKINTAS PADANGAS IR SKALDĄ

Municipal waste landfill leachate is formed at different stages of landfill operation and has a negative impact on a natural environment. According to the recently implemented waste management policy, landfill leachate in modern solid waste disposal sites has been monitored. Due to a complex composition of components for filtrate, over a long period of time, the processes of commutation in a drainable layer have been taking place, thereby reducing the porosity and permeability of the layer. Calcium, silicon and iron compounds are the main elements influencing a decrease in conductivity. Filtrate has formed in landfills and waste water and involved the process of precipitation percolating through waste. For 3 months, studies on two different drainage layers of filtration have been carried out. The obtained results have showed that for forming the landfill leachate drainage layer, a drainage rubble layer of 40% mixed with counter rubber waste can be successfully used. Santrauka Komunalinių atliekų sąvartynų filtratas susidaro sąvartyno eksploatacijos skirtingose stadijose ir turi neigiamą poveikį gamtinei aplinkai. Dėl sudėtingos komponentinės filtrato sudėties ilgą laiką drenažiniame sluoksnyje formuojasi kolmatacijos procesai. Pagrindiniai elementai, turintys įtakos laidumo sumažėjimui, yra kalcio, silicio ir geležies junginiai. Tyrimai buvo atliekami su dviem skirtingais kolonėlių užpildais, suformuotais iš drenažo skaldos ir smulkintų padangų sluoksnių, per kuriuos filtruojamas filtratas 3 mėnesius.

CLOGGING TEST OF LANDFILL LEACHATE DRAINAGE USING DIFFERENT FILLERS / SKIRTINGŲ UŽPILDŲ TINKAMUMO, SIEKIANT IŠVENGTI FILTRATO DRENAŽO UŽSIKIMŠIMO, TYRIMAS

Municipal waste landfill leachate formed at different stages of the operation of the landfill, has a negative impact on the natural environment. According to the newly implemented waste management policy on modern solid waste deposit sites, landfill leachate has to be monitored. Five experimental columns were constructed in size of 500 mm long and 200 mm in diameter. They were filled with different fillers. The flow of leachate allowed for calculation of the leachate volume per year in a landfill, where it was taken. The experiment was carried out for 365 days. Significant change of the porosity was determined in all columns. Although the landfill for this period represents only 1/50 or less of the operation time, the laboratory tests found that the drainage layer bandwidth of reduction in one year can have a negative impact in the long run of time, which will only increase congestion. For higher porosity value of the test substance, allowing for more impairment, a 2% points decrease in the value is less dangerous when the porosity value is of 57 or 45 percent, than of 29 or 47%. The main elements that influence the conductivity decrease are calcium, silicon and iron compounds. The change of these compounds was observed during lysimetric study, where the concentration of each month in all the columns was decreasing. The results showed, that the rubber used for creating fillers in columns provided for bigger porosity of the layer. It is the beneficial reason to use rubble and rubber waste mix for forming drainage layer in landfills. Santrauka Komunalinių atliekų sąvartynų filtratas, susiformuojantis skirtingais sąvartyno eksploatacijos etapais, daro neigiamą įtaką gamtinei aplinkai. Naujai įgyvendinama atliekų tvarkymo strategija. Šiuolaikinėse kietųjų atliekų deponavimo aikštelėse atliekama sąvartynų filtrato stebėsena. Eksperimentui atlikti sumontuotos 500 mm ilgio ir 200 mm skersmens kolonėlės buvo pripildytos skirtingų užpildų. Filtratas leistas apskaičiavus metinį sąvartyno filtro kiekį. Eksperimentas buvo atliekamas 365 dienas. Reikšmingi poringumo pokyčiai nustatyti visuose tirti naudotuose mišiniuose. Sąvartyno eksploatavimo atžvilgiu toks laikotarpis tėra 1/50 dalis ar dar mažiau eksploatavimo trukmės. Laboratoriniais tyrimais nustačius, kad drenažo sluoksnio pralaidumo sumažėjimas per vienerius metus gali turėti neigiamos įtakos, yra akivaizdu – per ilgą eksploatavimo laiką užsikimšimas tik didės. Kai tiriamos medžiagos poringumo vertė didesnė, leistinas didesnis jos sumažėjimas, t. y. poringumo vertei esant 57 ir 45%, jos sumažėjimas 2% punktais yra mažiau pavojingas nei esant 29 ar 47%. Pagrindiniai elementai, darantys įtaką laidumo sumažėjimui, yra kalcio, silicio bei geležies junginiai. Šių junginių koncentracijų pokytis buvo stebimas lizimetrinio tyrimo metu. Koncentracijos kiekvieną mėnesį visose kolonėlėse mažėjo. Rezultatai rodė, kad sąvartynų filtrato drenažiniam sluoksniui tinkamiausia naudoti drenažo skaldos ir gumos atliekų mišinį. Jo poringumas mažiausiai pakito.
