“…This trend of food waste being the major fraction is also apparent in other metropolises of the country such as Lahore as well as in many other developing countries [6,21,53,54]. However, since developed countries mostly use processed packed food, this trend is not necessarily followed in developed countries [24,38,55,56]. The presence of higher percentage of food waste indicates that the waste of Islamabad has a high potential for composting or bio-gasification.…”

“…Unfortunately, proper management of waste is mostly not possible because authentic data about waste generate rate, composition and the factors affecting both, are not always available [20,21]. If available, these waste characterization studies can be further used as a baseline to generate an optimal waste management plan [6,13,[20][21][22] using life cycle assessment (LCA) approach [23][24][25][26]. The importance of waste characterization for the establishment of waste management program is also emphasized by following studies [20,[27][28][29][30][31][32][33][34][35][36][37].…”

Abstract:The current study aims to analyze and compare the quantity and composition of municipal solid waste (MSW) at three socio-economic levels of population during all four seasons of the year (spring, summer, monsoon and winter). In this study, 2164.75 kg of MSW was evaluated, from 1260 samples collected from 45 households. The average waste generation was estimated to be 0.6 kg per capita per day. Waste generation rate for high, middle and low income groups was 0.890, 0.612 and 0.346 kg per capita per day, respectively. Nevertheless, season specific analysis indicated waste generation rates of 0.78, 0.58, 0.48 and 0.75 kg per capita per day in spring, summer, monsoon and winter, respectively. A two way ANOVA statistical analysis further illustrated a significant effect (p = 0.00) of economic level and seasons on the amount and composition of waste generated by the community. Moreover, the collected waste was segregated into 42 categories, where the highest was the organic fraction (57%), then diapers (12%), followed by plastic (8%), cardboard (3%) and paper (2%). The amounts of textile, diapers and plastics were highest in the lowest income group, while tetra packs, metal, paper and yard waste were maximum in the high income group. It is concluded that the high income group generated the highest amount of waste and waste generation rate is higher in the seasons of spring and winter compared to the other two seasons.

“…Quantification of environmental impacts of the existing system is partially a function of the waste characteristics [2,46,47]. A systematic study was carried out for one week during all four seasons (Summer, Monsoon, Winter, Spring) of a year from June 2013 to March 2014 [42,48].…”

Environmental Quantification of the Existing Waste Management System in a Developing World Municipality Using EaseTech: The Case of Bahawalpur, Pakistan

2018

Evaluation of existing operational and managerial provisions and identification of specific actions that fit and impact in a local context is key to find sustainable solutions. The study aims to develop an understanding of existing waste management practices for a medium sized city of Pakistan and to quantify the related environmental impacts using life cycle assessment (LCA). The existing waste management system in "Bahawalpur", a city with predominant rural-urban infusion, is characterized by straining resources, low generation rates (0.424 kg/capita/day), prominent source separation, high scavenging activities and open dumping practices. The waste composition analysis proposes organic wastes as the largest constituent (64%) followed by recyclables (27%) and inerts (9%). The LCA model "EaseTech" used to quantify the environmental performance of existing waste management arrangements illustrated that existing waste management system in Bahawalpur City has tangible effects on climate change (3.16 × 10 7 kg CO 2 -Eq) and ecotoxicity (3.12 × 10 6 CTU) categories, while depletion of abiotic resources fossil (−9.60 × 10 7 ) category points up most environmental savings. Significant environmental compensations for different impact categories are offered due to high source separation and recycling trade off. The overview necessitates suitable modification in existing waste disposal practice that poses severe impacts on the environment.

“…Çapak PE, çapak PP, çapak PET ve çapak PS yıkama işlemine tutulduktan sonra agromel makinasında yoğunlaştırılarak granül hale getirilip, satılmak üzere depolanır. Plastiklerin geri dönüşümü esnasında atık hammadde işlenmemiş atığın tam olarak yerini alamayacağından % 28 madde kaybı olacaktır [16]. Toplama-ayrıma tesisi için forklift, ayırma bandı ve pres-balyalama makinesi gerekirken, plastik geri dönüşümü için forklift, ayırma bandı, plastik kırma makinası, yıkamadan sonrası için sıkma makinası, agromel makinası ve plastik extruder (granül) makinesi gerekmektedir.…”

ÖZSakarya-Serdivan ilçesi ambalaj atıkları yönetiminin çevresel etkilerini yaşam döngüsü analizi (YDA) ile belirlemek bu çalışmanın ana amacıdır. Yaşam döngüsü analizinde Simapro 8.02 yazılımı ve CLM-IA etki kategorisi kullanılmıştır. Çalışmanın fonksiyonel birimi olarak Sakarya-Serdivan'da toplanan 1 ton ambalaj atığı ele alınmıştır. Sistem sınırları ambalaj atığının toplanması, toplama-ayırma-geri dönüşüm tesisine nakliyesi, karışık ambalaj atıklarının ayrılması, kağıt, karton, metalin preslenip geri dönüşüm firmalarına satılması, plastik atıkların granül hale getirilmesi ve satılması, cam atıkların preslenmeden ilgili firmalara satılması, geri kalan artıkların veya geri dönüştürülemeyen malzemelerin düzenli depolamada bertarafıdır. Bu çalışmada ambalaj atığı yönetimi için 3 senaryo kurgulanmış olup, senaryolardan ikisinde gerçek ve yönetmelikte olması gereken oranlarda geri dönüşüm yapılırken, son senaryoda hiç geri dönüştürülmeden düzenli depolamaya gönderilmektedir. Sonuçlara baktığımızda, ambalaj atıklarının depolanması en kötü bertaraf alternatifidir. En büyük olumsuz etkide tatlı su ve deniz ekotoksisitesi ile ozon tabakasının tahribatı ve fosil yakıtların abiyotik tüketiminde hesaplanmıştır. Anahtar Kelimeler: ambalaj atıkları, atık yönetimi, yaşam döngü analizi (YDA)The use of life cycle analysis on the packaging waste management ABSTRACT The aim of this study is to determine the environmental impacts of the packaging waste management for Sakarya-Serdivan by using life cycle analysis (LCA). Simapro 8.02 software with CLM-IA impact category was used to perform the LCA. Functional unit was considered as one ton of packaging waste collected in Sakarya-Serdivan. System boundaries include collection of packaging waste, transportation into sortingrecycling plant, separation of mixed packaging waste, sale of pressed papers, cardboards, metals and unpressed glasses to the relevant companies and recycling of plastics into granulate form and disposal of residual waste or non-recyclable materials by landfilling. In the study, 3 scenarios were modeled for packaging waste management. While packaging wastes are recycled at real and the regulation rates for two scenarios, landfilling of packaging waste without any recycling are focused on the last scenario. According to the results, landfilling of packaging waste is the worst alternative. It was observed higher negative impacts in the freshwater aquatic ecotoxicity, marine aquatic ecotoxicity, ozone layer depletion and abiotic depletion (fossil).
