ABSTRACT As part of environmental management policies in Europe, separate collection of organic household waste and nonorganic household waste has become increasingly common. As waste is often stored indoors, this policy might increase microbial exposure in the home environment. In this study we evaluated the association between indoor storage of organic waste and levels of microbial agents in house dust. The levels of bacterial endotoxins, mold β(1→3)-glucans, and fungal extracullar polysaccharides (EPS) of Aspergillus andPenicillium species were determined in house dust extracts as markers of microbial exposure. House dust samples were collected in 99 homes in The Netherlands selected on the basis of whether separated organic waste was present in the house. In homes in which separated organic waste was stored indoors for 1 week or more the levels of endotoxin, EPS, and glucan were 3.2-, 7.6-, and 4.6-fold higher, respectively (all P < 0.05), on both living room and kitchen floors than the levels in homes in which only nonorganic residual waste was stored indoors. Increased levels of endotoxin and EPS were observed, 2.6- and 2.1-fold (P < 0.1), respectively, when separated organic waste was stored indoors for 1 week or less, whereas storage of nonseparated waste indoors had no effect on microbial agent levels (P > 0.2). The presence of textile floor covering was another major determinant of microbial levels (P < 0.05). Our results indicate that increased microbial contaminant levels in homes are associated with indoor storage of separated organic waste. These increased levels might increase the risk of bioaerosol-related respiratory symptoms in susceptible people.

Abstract This study was conducted to determine the influence of environmental factors on the prevalence of house dust mites in student dormitories of Bandar Abbas city. In this study, 64 dust samples were collected from seven randomly selected dormitories located in various areas of the Bandar Abbas. The collected mites were isolated and mounted in Hoyer’s medium and identified using a morphological key. The associations between the environmental factors and the density of house dust mites were investigated. In total, 1,093 adult mites were collected and identified. They consisted of four species including Dermatophagoides pteronyssinus Trouessart (57.6%), Dermatophagoides farinae Hughes (24.3%) and Dermatophagoides evansi Fain (14.9%) (Acari: Pyroglyphidae), and Cheyletus malaccensis Oudemans (3.2%) (Acari: Cheyletidae). All of the dormitories were contaminated by more than one house dust mites species and the mean density of house dust mites in dormitories was 8.3 ± 0.2 mites/g of dust. There was a significant relationship between average house dust mites density and some of environmental factors such as relative humidity, temperature, floor covering type, and number of occupants (P &lt; 0.05). Results of this study revealed that two major allergenic dust mites, D. pteronyssinus and D. farinae, were the most prevalent and collected from all of dormitories and some of indoor environmental factors found to influence mites’ population.

Starting Point

The absence of accurate information on the state of waste is a challenge to the solid waste management system in Syria. The local authorities commonly estimate the quantity of waste produced and its characterisation, which is the starting point for solid waste management planning. So, this paper aims to evaluate the generation and composition of household solid waste in Homs city, Syria. Also, the study presents factors influencing the waste generation rate and the waste composition. The study was carried out in 300 families from four zones in Homs city, and three sampling stages were conducted during the study duration, which started in July 2017 and ended in February 2019. The outcomes show that an average of 0.68 kg/per/day solid waste generated was calculated for the entire study area in Homs city. Also, the data analysis presents that organic waste constitutes the largest component in the waste mixture (69.1%) followed by plastic (10.6%), inert materials (8.7%), paper (4.6%), textile (2.5%), metal (1.2%), glass (1.1%), wood (0.6%), and hazardous materials (1.6%). The multiple linear regression results showed that the adjusted R2 value was found to be 0.557, 0.839, and 0.709 for the waste generation per capita, the daily household organic waste generation, and the daily household packaging waste generation, respectively. Also, according to Pearson’s coefficient values, a positive correlation was found between household waste generation and monthly income (r = 0.626), household size (r = 0.37), and age of the household head (r = 0.517), whereas a negative correlation was found between household waste generation and the education level of the household head (r = −0.649).

Waste Generation Rate

Bhaktapur Municipality has been performing better to keep the city clean. However, scarcity of space for the land filling of the solid waste and proper segregation of waste at the source has been a hurdle for the Municipality. This paper aims to determine solid waste generation rate and to analyze overall situation of solid waste management of Bhaktapur Municipality. However, the data will not represent the seasonal and occasional variations. Additionally, waste from street-sweeping and large-scale institutional and commercial components of the Municipality has not been assessed. Arkin and Colton (1963) was referred for the sample size determination. Sample of 376 households were taken accordingly. Twenty representative samples each for commercial and institutional establishments were selected, and one each for special cases such as hospital, slaughter house and poultry has been assessed. Municipal household waste generation was found to be 0.093kg per capita per day which was chiefly composed of 77% organic, 18% plastic and 3% paper. Organic waste has been a major waste for institutions such as schools whereas at governmental and public offices, paper is the predominantly generated waste. Among commercial establishments, shops and restaurants mostly generate organic waste and that for departmental stores has been paper. Though collection system was found to be satisfactory, treatment and final disposal have been unsustainable. Available treatment facilities have been shut down whereas other infrastructural components have been lacking.

Waste is a problem that must be faced by residential communities both in urban and rural settlements, so it needs to be systematically structured and sustainable. Conventional waste handling that has been implemented by the community cannot produce an appropriate solution, this is evident that there is still a large volume of waste that has not been managed properly. The purpose of implementing community service activities in the village of Sedapurklagen in Benjeng Gresik is to utilize household waste through compoter and biopori as well as the application of Biopori to treat household waste that can also reduce waterlogging during rain. The implementation method is used so that the purpose of this service activity is to empower the community about managing household waste to be composted through composter, as well as training on composting from composter and biopori. The target of this activity is the mothers of family welfare coaching (PKK) in the village of Sedapurklagen, Benjeng Gresik. The result of this service is that the community has begun to process organic waste to make compost and million biopori pipes around the Posapur, Sedapurklagen Gresik to reduce the presence of standing water during the rainy season.

Waste has become a problem that is really worrying everywhere. If you pay close attention, there are indeed a number of factors that cause waste problems to become serious. First, population growth. Second, more and more instant food with plastic packaging. Third, the habit of littering, the habit of consuming instant food in packaging, to the habit of throwing garbage without sorting between organic and non-organic waste will damage the ecosystem. The same problem is also experienced by Berbek Village in Sidoarjo Regency, the problem of waste and flooding that is always faced by the city cannot only be the responsibility of the government, but the community as one of the producers of household waste should always help reduce the amount of waste. Thisneeds to provide an understanding to the community of environmental concerns, especially regarding household waste management and water conservation for the future based on water conservation. The results achieved from this activity are that the village community is aware of and understands the importance of a clean environment, there is no garbage scattered, puddles or floods can be reduced, and are able to practice independent waste management methods.

ABSTRAKSalah satu dampak dari proses pembangunan adalah pencemaran dan kerusakan lingkungan. Pertumbuhan penduduk yang pesat terutama di daerah perkotaan dengan perilaku membuang sampah yang tidak baik menyebabkan berbagai limbah yang harus diserap oleh lingkungan, terutama limbah domestik atau limbah rumah tangga. Komposisi sampah organik menempati persentase tertinggi hingga 57% di Kota Bandung, dimana limbah sisa makanan yang menempati urutan teratas yaitu sebesar 40%. Masyarakat dan pemerintah saja tidak cukup untuk mengatasi persoalan pengelolaan sampah. Keterlibatan dan partisipasi aktif perusahaan sebagai pihak swasta melalui kegiatan tanggung jawab sosial perusahaan dapat dilakukan melalui program-program yang mendukung pengolahan limbah organik berkelanjutan. Pengembangan program CSR yang baik pada suatu perusahaan sebaiknya dikaitakn dengan kebutuhan dan persoalan yang dihadapi masyarakat sekitar. Model Social Responsible Business Practice, merupakan salah satu jenis program yang bertujuan untuk mensejahterakan masyarakat, tapi juga memiliki korelasi positif dalam peningkatan produktivitas perusahaan secara operasional. Model praktik ini, memungkinkan aktivitas perusahaan yang salah satunya mencakup penyediaan fasilitas yang memenuhi tingkat keamanan dan keselamatan lingkungan dan dapat memelihara aktivitas pembangunan berkelanjutan. PT. Pertamina TBBM Bandung Group merupakan salah satu BUMN yang peduli dengan inovasi penanganan masalah sampah di Kota Bandung, melalui program BU MANIK (Budidaya Maggot dan Pupuk Organik), sejalan dengan program KANG PISMAN (Kurangi, Pisahkan, Manfaatkan) milik pemerintah Kota Bandung, yang bertujuan untuk membudidayakan maggot sebagai media utama pengurai limbah organik serta pakan ternak alami. Efektifitas program ini bergantung pada CSR PT. Pertamina TBBM Bandung Group sebagai lembaga yang memfasilitasi pelaksanaan program dan kelompok bank sampah sebagai komunitas yang diberdayakan, serta keterlibatan masyarakat dan dukungan pemerintah.Kata kunci: CSR, pengelolaan sampah, sumber daya berkelanjutan, pemberdayaan ABSTRACTOne of the impacts of the development process is environmental pollution and damage. Rapid population growth, especially in urban areas with bad waste disposal behavior, causes a variety of waste that must be absorbed by the environment, especially domestic waste or household waste. The composition of organic waste occupies the highest percentage up to 57% in the city of Bandung, where food waste that occupies the top rank is 40%. The community and the government alone are not enough to overcome the problem of waste management. The involvement and active participation of companies as private parties through corporate social responsibility activities can be done through programs that support sustainable organic waste treatment. The development of a good CSR program in a company should be related to the needs and problems faced by the surrounding community. Social Responsible Business Practice Model, is one type of program that aims to prosper the community, but also has a positive correlation in increasing company operational productivity. This practice model allows company activities, one of which includes the provision of facilities that meet the level of environmental security and safety and can maintain sustainable development activities. PT. Pertamina TBBM Bandung Group is one of the BUMN that is concerned with the innovation of handling waste problems in the city of Bandung, through the BU MANIK (Cultivating Maggot and Organic Fertilizer) program, in line with the KANG PISMAN program (Reduce, Separate, Utilize) the Bandung city government, which aims to cultivate maggot as the main media to decompose organic waste and natural animal feed. The effectiveness of this program depends on the CSR of PT. Pertamina TBBM Bandung Group as an institution that facilitates the implementation of programs and groups of waste banks as an empowered community; as well as community involvement and government support.Keywords: CSR, waste management, sustainable resource, empowerment
