The uncontrolled growth of urban areas resulting from economic aspects, political, cultural and educational, combined with a marked change in the meaning of human needs and aspirations, intensified forms of production and exploitation, generating irreversible effects related to nature. History shows that it is up to society (civil and political) to seek knowledge and skills so that we can preserve what remains of natural resources, because you have to minimize environmental impacts, and better understand the importance of the environment for the survival of human species. Exploratory research procedures were used, survey, based on the literature review, the documentary survey and field. The study allowed to expose part of the reality experienced by waste pickers Iporá (GO), and aimed to show the importance of these collectors both in relation to their work that contributes to improving the quality of the environment, and in relation to their own identity (optical differentiated in relation to its role). Concludes that despite the little recognition of its importance (not visible) by society gets support the family by collecting cans, PET bottles, cardboard and other solid and undeniably contribute directly to the process of preservation of the environment. / O estudo objetivou analisar os catadores de Resíduos Sólidos de Iporá (GO), sua percepção em relação ao meio ambiente no qual estão inseridos, a identidade , o seu posicionamento na sociedade, a importância do seu trabalho que contribui para melhorar a qualidade do meio ambiente, e também, explicitar a sua própria identidade. Na análise acentua-se como o crescimento desordenado dos aglomerados urbanos decorrente dos aspectos econômico, político, culturaleducacional, associado a uma profunda mudança no significado das necessidades e aspirações humanas, intensificou as formas de produção e exploração, e que gerou efeitos irreversíveis à natureza. A história mostra que cabe à sociedade (civil e política) buscar conhecimentos e habilidades para que se possa preservar o que ainda resta de recursos naturais, porque é preciso minimizar os impactos ambientais, e compreender melhor a importância do meio ambiente para a sobrevivência da espécie humana. Foram utilizados procedimentos de investigação exploratória, a revisão teórica, o levantamento documental e de campo (survey). Concluiu que apesar do pouco reconhecimento da importância dos catadores (não visibilidade) por parte da sociedade, eles obtêm o sustento da família, através da coleta de latinhas, garrafas PET, papelões e outros resíduos sólidos e, inegavelmente, contribuem diretamente com o processo de preservação do meio ambiente.

Using GIS in Solid Waste Management Planning : A case study for Aurangabad, India

Shaikh, Moiz Ahmed January 2006 (has links)
<p>Waste management is a global environmental issue which concerns about a very significant problem in today’s world. There is a considerable amount of disposal of waste without proper segregation which has lead to both economic and environment sufferings. It is still practiced in many cities. There is a tremendous amount of loss in terms of environmental degradation, health hazards and economic descend due to direct disposal of waste. It is better to segregate the waste at the initial stages where it is generated, rather than going for a later option which is inconvenient and expensive. There has to be appropriate planning for proper waste management by means of analysis of the waste situation of the area.</p><p>This paper would deal with, how Geographical Information System can be used as a decision support tool for planning waste management. A model is designed for the case study area in an Indian city for the purpose of planning waste management. The suggestions for amendments in the system through GIS based model would reduce the waste management workload to some extent and exhibit remedies for some of the SWM problems in the case study area. The waste management issues are considered to solve some of the present situation problems like proper allocation and relocation of waste bins, check for unsuitability and proximity convenience due to waste bin to the users, proposal of recyclable waste bins for the required areas and future suggestions. The model will be implemented on the Aurangabad city’s case study area data for the analysis and the results will suggest some modification in the existing system which is expected to reduce the waste management workload to a certain extent.</p>

A study on the causality between disbursement incurred from waste management and the effectiveness of control measures

Tsai, Han-Tang 01 September 2012 (has links)
The Environmental Protection Administration of Executive Yuan has been promoting the environmental protection policy for years, hoping to achieve the goal of ¡§zero waste¡¨ and meet the international environmental standard by executing source minimization and resource recycling. The study aims to investigate the causality between the disbursement incurred from waste management and the effectiveness of control measures of the 22 Taiwan¡¦s administrative regions from 2001 to 2010; variables of the examination are, disbursement incurred from waste management , disposal or treatment rate of municipal waste, and recycling rate of enforcement authority. After the gathering of data, the Granger test is conducted to determine the causality. Given that the data of disbursement incurred from waste management is hard to gather and the details of the actual disbursement of the evaluation indices are impossible to separate, the study postulates that, with consideration of the consistency and continuity of the budgeting process and the massive accident, all the disbursement incurred from waste management is used for the said purpose. The result of the empirical research indicates that disposal or treatment rate of municipal waste and disbursement incurred from waste management are not causally related. In the Granger test, the correlation between disbursement incurred from waste management and recycling rate of enforcement authority are significant at the 0.01 level; the correlation between recycling rate of enforcement authority and disbursement incurred from waste management are significant at the 0.1 level. Therefore, the ¡§Zero Waste¡¨ and ¡§source minimization and resource recycling¡¨ policy promoted by the Administration is effective in reducing the disbursement incurred from waste management. If we adhere to the environmental policy, we can not only improve the environmental health and life quality, but also be able to reduce the expense of waste management and invest the resource on other departments to achieve the effect of protecting the environment while maintaining economic growth.

Legal Regulation of Waste Management: Current Issues / Teisinis atliekų tvarkymo reguliavimas: probleminiai aspektai

Vasiliauskas, Martynas 13 December 2011 (has links)
The author poses a question whether the current legal regulation of waste is proper. The question is answered by analyzing five issues: variety of the concepts of waste (waste can be perceived in distinct manners and the current concept aggravates the solution of two principal waste problems – danger to the environment and danger to human health); non-systematic use of terms (improper terms are used in Lithuanian legal acts); the jurisprudence of Lithuanian courts in explaining the concept of waste (the courts do not perceive waste properly); the twofold term of the municipal/household waste in Lithuanian legal acts (municipal/household waste is regulated by using the same term, thus it is not clear for which waste persons are taxed); the application of the municipal levy for waste management (the current model does not encourage to preserve the environment). The author concludes that the variety of the concepts of waste, the disagreements among the scholars on the question, the difficulties encoutered by the courts and non-ameliorating status of the environment show that it should be reasonable to discard the current legal regulation of waste. The two principal problems posed by waste and unsuccessfully solved by the current legal regulation are determined principally by the objects which are not in any possesion. Then waste should be perceived as an object which is not in a possesion and the legal regulation should be orientated in making all the objects to have a possesor. / Disertacijoje keliamas klausimas, ar esamas atliekų tvarkymo teisinis reguliavimas yra tinkamas. Į šį klausimą atsakoma analizuojant penkis atliekų tvarkymo teisinio reguliavimo probleminius aspektus: (1) atliekų sampratų įvairovę (atliekas galima suvokti labai įvairiai, o dabartinė atliekų samprata apsunkina dviejų pagrindinių atliekų keliamų problemų – pavojingumo aplinkai ir žmogui - sprendimą); (2) nesusistemintą terminiją (teisės aktuose vartojami netinkami terminai); (3) Lietuvos teismų praktiką aiškinant atliekų sąvoką (teismai atliekas suvokia netinkamai); (4) dvilypę komunalinių atliekų sąvoką (komunalinės atliekos teisės aktuose suvokiamos dvejopai, todėl neaišku, už kokių konkrečiai atliekų tvarkymą asmenys yra apmokestinami); (5) vietinės rinkliavos už komunalinių atliekų surinkimą ir atliekų tvarkymą taikymą (rinkliava neskatina asmenų tausoti aplinkos). Daroma išvada, kad atliekų sampratų įvairovė, teisės mokslininkų nesutarimai, ką laikyti atliekomis, teismų patiriami sunkumai nagrinėjant atliekų bylas ir negerėjanti aplinkos padėtis rodo, kad būtų tikslinga atsisakyti esamo atliekų teisinio reguliavimo. Dvi pagrindines atliekų problemas, kurias siekiama išspręsti esamu atliekų teisiniu reguliavimu, iš esmės kelia tik nevaldomi objektai. Tuomet atliekomis reikėtų laikyti tik tuos objektus, kurie nėra valdomi, o teisiniu reguliavimu siekti, kad visi objektai būtų valdomi.
