Proper management of food waste, a major component of municipal solid waste (MSW), is needed, especially in developing Asian countries where most MSW is disposed of in landfill sites without any pretreatment. Source separation can contribute to solving problems derived from the disposal of food waste. An organic waste source separation and collection programme has been operated in model areas in Hanoi, Vietnam, since 2007. This study proposed three key parameters (participation rate, proper separation rate and proper discharge rate) for behaviour related to source separation of household organic waste, and monitored the progress of the programme based on the physical composition of household waste sampled from 558 households in model programme areas of Hanoi. The results showed that 13.8% of 558 households separated organic waste, and 33.0% discharged mixed (unseparated) waste improperly. About 41.5% (by weight) of the waste collected as organic waste was contaminated by inorganic waste, and one-third of the waste disposed of as organic waste by separators was inorganic waste. We proposed six hypothetical future household behaviour scenarios to help local officials identify a final or midterm goal for the programme. We also suggested that the city government take further actions to increase the number of people participating in separating organic waste, improve the accuracy of separation and prevent non-separators from discharging mixed waste improperly.

Every day residents of Lubuklinggau City produce 158.2 tons of household waste. The concept of reuse, reduce, and recycle is still the best way to manage and handle waste with various existing problems. Household waste is divided into 2 parts into organic and inorganic waste. Organic waste is waste that easily decomposes such as food scraps, vegetables, dry leaves, which can still be processed and utilized. Organic waste can be processed into organic fertilizer. The methods used in this service are lectures, discussions, demonstrations and practices of processing household organic waste into organic fertilizer. This activity received a very good response from residents and the Ponorogo Village, Lubuklinggau City, because after participating in the activity, residents received information and were able to process household organic waste to be used as organic fertilizer. In addition, this activity helps the Lubuklinggau City government overcome the problem of household organic waste in Ponorogo Village, Lubuklinggau City and is expected to be a model for other families.

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

A lot of waste from agriculture, industry, household and food waste is accumulated every year in Lithuania. Waste is polluting environment very intensively. From sanitarian point of view there can appear dangerous sources for people and other biological objects. The main method for utilisation of waste still remains landfilling. So as a huge problem appears operation of landfills, cumulation of leachate and biogas. The last years Vilnius city municipality directly changed the waste managing strategy. As it was estimated, food waste forms about 46,6 -56,6 % from total household waste amount. It was decided to turn this source from landfill to composting facilities, organise separate food waste collection from companies and habitants. The system was iniciated in 1997, but it develops very slowly. A private company "Chitinas" has started its work independently in neighbouring Vilnius city district. Two main unordinal methods were used for destruction of organic waste, both very usual in nature, but still rarely used in practice by farmers. Such methods are called in Lithuania "nontraditional farming". We estimate these methods as modem and perspective for organic waste destruction in big cities. With their help we can get ecologically safe, good natural fertilizers, without seeds and infections, having less nitrates and fosphates. Besides, we get an alternative product - material called "chitin", which could be chemically purified and has a perfect future in chemistry and medicine.

Food waste is becoming an important issue in light of population growth and global food security concerns. However, data on food wastage are limited, especially for developing countries. Global estimates suggest that households in developed countries waste more food than those in developing countries, but these estimates are based on assumptions that have not been tested. We therefore set out to present primary data relating to household food waste disposal for South Africa within the sub-Saharan African context. As the Gauteng Province contributes about 45% of the total municipal waste generated in South Africa, the case study area covers two of the large urban metropolitan municipalities in Gauteng, namely Ekurhuleni and Johannesburg, with a combined population of 8.33 million, representing nearly 15% of the South African population. Municipal solid waste characterisation studies using bulk sampling with randomised grab sub-sampling were undertaken over a 6-week period during summer in 2014 (Johannesburg) and 2016 (Ekurhuleni), covering a representative sample of the municipal waste collection routes from households in each of the two surveyed municipalities. The food waste component of the household waste (excluding garden waste) was 3% in Ekurhuleni and 7% in Johannesburg. The results indicate that an average of 0.48 kg (Ekurhuleni) and 0.69 kg (Johannesburg) of food waste (including inedible parts) is disposed of into the municipal bin per household per week in the two municipalities, respectively. This translates into per capita food waste disposal of 8 kg and 12 kg per annum, respectively, in South Africa as compared to the estimated 6–11 kg per annum in sub-Saharan Africa and South and Southeast Asia.

Background: Waste is part of environmental problems because the increase in volume of waste correlates with population growth and efforts to reduce waste are still limited. Pataan Village which is one of the villages in Sambeng Subdistrict is also inseparable from the garbage problem. Most of the household waste will be collected in the yard and then burned, both organic and inorganic waste. In Pataan Village, there is already a 3R Waste Disposal Site (TPS) which functions as a place to collect garbage and a place to sort waste, unfortunately it is not functioned optimally due to various obstacles. Purpose: Solve the problem of managing organic waste especially corncobs by maximizing it as a mushroom planting media. Method: Socialization, training and assistance of mushroom cultivation using corncobs media to youth groups who are members of the Karang Taruna Organizations in Pataan Village. Results: The results of training and assistance for 25 days, it can be noted that the optimization of corncobs as a medium for mushroom cultivation can be an effective solution in handling the waste problem in Pataan Village and has the potential to bring up new commodities in Pataan Village in the form of janggel mushrooms. Conclusion:Partners get increased knowledge and skills in utilizing corncobs as a medium for cultivating janggel mushrooms. So that in the next period can be given about how the processing of the janggel mushroom in order to have added value.

This dedication was carried out to improve the health and welfare of the community through the assistance of Village Appreciative Planning in Benelan Kidul Village, Singojuruh Subdistrict, Banyuwangi Regency. The results of community service show that the community realizes that the problem of waste must be handled together with all elements of the community. Clean and healthy living is the desire of all citizens. Household Waste Sorting is based on the results of the Healthy Lifestyle Training that has been carried out in each hamlet with PKK cadre participants and study group mothers. The transportation system from households is temporarily collected in a sorting place located in each hamlet, where the selection points are determined by the hamlet head. Waste sorting is carried out in temporary sorting sites located in each hamlet by sorting out Organic and Inorganic waste. Where for organic waste is managed into fertilizer while inorganic waste, especially plastic waste will be managed into plastic ore. Garbage Bank is a business unit that is under the coordination of BUMDes so that marketing of organic and inorganic waste sorting results will be coordinated through BUMDes.

Since the food system will inevitably produce food waste, it is recommended that it be captured and recycled for more efficient use rather than being disposed of as solid household waste. Therefore, it is advantageous to promote food waste as poultry feed. In order to study the feeding feasibility of a poultry Lab- Prepared Feed (LPF) based on kitchen food waste as well as their nutritional value, the tests were carried out near Taza city on an organic chicken farm, in Eastern Morocco. The results of consumption indices concerning organic chickens treated only by Lab-Prepared Feed showed average values of 1.18 and 1.17 for tests 1 and 2 successively. According to the results obtained, the tests proved the feeding feasibility of a Lab-Prepared Feed (LPF), it appears to be a good substitute for commercial foods. The study may help to ensure the recovering of food waste materials as a new poultry feed substitute.
