The first step that possible for Surabaya University (Ubaya) to realize a sustainability campus was waste production reduction. A research related to solid waste management in Ubaya need to be  conducted. The aims of the research were 1. To determinate the economical organic solid waste composition in faculty of engineering 2.  Estimating the quantity of economical organic solid waste in faculty of engineering 3. Calculating the greenhouse gas that can be reduced by managing the economical organic solid waste. The scope of calculation was CH4 generation. Research is done by survey of solid waste generation. Survey was conducted  at faculty of engineering Ubaya, in TA building until TS building plus faculty of engineering gazebo. The estimation of economical organic solid waste was taken for eight days in September 2016. The calculation of green house emission from solid waste was referred to Intergovernmental Panel on Climate Change (IPCC)  2006 guidelines. The results of the research indicated that the composition of economical organic solid in the faculty of engineering was white paper, brown paper, cardboard, and juice and tea packaging. The average quantity of economical organic waste generated in the faculty of engineering per day  were white paper: 5.44 kg, 1.055 kg of brown paper, cardboard 2.51 kg and 0,765 kg of tea and juice packaging. Greenhouse gas (CH4), which could be lowered if the economical organic waste is managed was around 1.14 kg / day. Keywords: sustainability, IPCC, campus, organic solid waste

Cattle dung, cooked food waste, and chicken droppings mixed with coffee husks have been used separately and also as mixtures to form anaerobic digestion slurries in a bid to treat to degrade the organic fractions of these wastes and recycle the bio-fertilizer after recovering biogas. Single and mixed substrate slurries evolved significant quantities of methane within 27days together with reduced mass of soil conditioner. The volume of biogas formed in cogeneration mixtures were higher than for single substrate digestion due to the C/N ratio shifting to near 30:1 as a result of mixing. So degradation of organic pollutants was higher in mixed substrate digestion mixtures. Our study yielded average volumes ranging from 315 to 435+ 5.65.mL/L which was in agreement with what is in literature. Digestion of cattle dung, cooked waste foods, and droppings of chicken and mixed substrate slurries using sludge inoculums was very effective in degrading solid waste from homes, thus detoxifying it to bio-fertilizers. Although both single and mixed substrate digestion of waste yielded high enough volumes of biogas; digestion of slurry of mixed organic solid waste substrates is better method of waste management. Digestion of garbage from Kampala should be tested at macro levels at both ambient and mesophilic temperatures. There is need to try out the garbage digestion experiments in the semi-arid towns as well as very cold towns in Uganda.

Bean Leaves

The landfill's capacity is currently decreasing, so solid waste reduction needs to be increased. Organic solid waste is generated by daily activities. The objective of the study was to determine the composting and composition of the growth of leaves of the long bean plant (Vigna cylindrical (L.)). Methods used in the composting process is the takakura method. The 80% compositions of compost are spinach waste. The composting process accelerated by the addition of local microorganisms (MOL) from fruit and compost to accelerate decomposed of organic waste. Variables on this research were functions of the time for the composting process and the amount of compost with the soil to the long bean plant (Vigna cylindrical (L.)). Compost collection time was determined as a research variable with variations on 14, 28, and 42 days, while variations in compost and soil composition tested on a long bean plant (Vigna cylindrical (L.)) of 1: 1 and 1: 2. The results showed good leaves growth period was 28th day with a composition 1: 1. Kapasitas Tempat Pemrosesan Akhir (TPA) saat ini semakin berkurang, sehingga reduksi sampah perlu ditingkatkan. Sampah organik merupakan salah satu sampah yang banyak dihasilkan oleh aktivitas seharihari. Tujuan penelitian yakni mengetahui pengaruh waktu pengomposan dan komposisi kompos terhadap laju pertumbuhan daun tanaman Kacang Panjang (Vigna cylindrica (L.)). Metode yang digunakan untuk membuat kompos yaitu metode takakura. 80% komposisi kompos berasal dari sisa sayur bayam. Pembuatan kompos dilakukan dengan menambah mikro organisme local (MOL) dari buah dan kompos jadi untuk mempercepat sampah organik terdekomposisi. Variabel yang digunakan yaitu variasi waktu pengambilan kompos dan variasi komposisi kompos dengan tanah terhadap Kacang Panjang (Vigna cylindrica (L.)). Waktu pengambilan kompos ditentukan sebagai variabel penelitian dengan variasi pengambilan pada hari ke - 14, 28, dan 42, sedangkan variasi komposisi kompos dan tanah yang diujikan terhadap tanaman Kacang Panjang (Vigna cylindrica (L.)) sebesar 1 : 1 dan 1 : 2. Hasil penelitian menunjukkan laju pertumbuhan daun paling besar yaitu pada variasi waktu pengambilan kompos hari ke – 28 dengan komposisi 1 : 1.

Msw Management

The studies on municipal solid waste (MSW) management in Pakistan and its impacts on greenhouse gas (GHG) emissions are glaringly missing. Therefore, this study examines the effect of MSW management on GHG emissions in Pakistan and suggests the best suitable strategies for alleviating GHG emissions. The Intergovernmental Panel on Climate Change (IPCC) 2006 waste model (WM) was used to create inventory of GHG emissions from landfilling. The solid waste management GHG (SWM-GHG) calculator and strengths–weaknesses–opportunities–threat (SWOT) analyses were used as strategic planning tools to reduce GHG emissions by improving MSW management in Pakistan. The IPCC 2006 WM estimated 14,987,113 metric tonnes (Mt) carbon dioxide equivalents (CO2-eq) of GHG emissions in 2016. The SWM-GHG calculator, on the other hand, estimated 23,319,370 Mt CO2-eq of GHG emissions from management of 30,764,000 Mt of MSW in 2016, which included 8% recycling, 2% composting, and 90% disposal in open dumps. To reduce GHG emissions, two strategies including recycling-focused and incineration-focused were analysed. The recycling approach can reduce more GHG emissions than incineration, as it can reduce 36% of GHG emissions (as compared to GHG emission in 2016) by recycling 23% of MSW, anaerobically digesting 10% of MSW, and disposing of 67% of MSW in sanitary landfills (with energy recovery). Moreover, the SWOT analysis suggested integration of the informal sector, adoption of anaerobic digestion and formulation of explicit MSW regulations for improving the current management of MSW which will also result in lower GHG emissions.

Heavy Burden

TPA is the main priority in handling municipal solid waste in Indonesia, with many problems and challenges. TPST is one of other alternatives in handling solid waste in accordance with Solid Waste Management Law No. 18 year 2008, therefore it has an important role in reducing heavy burden of TPA. Activities that can be done in TPST are collecting, sorting, re-using, re-cycling, treatment of fi nal processing, either for organic solid waste or for inorganic solid waste. However, based on characteristic of municipal waste, it’s better the stressing activities are pointed to organic solid waste treatment that make composting as the main alternative activity. Government support and help are much needed in order that TPST activity can be optimally done.Keywords : municipal solid waste, integrated treatment facility, composting

The Impact

Currently, the Ministry of Housing and Local Government manage solid waste in Malaysia, with the participation of the private sector. Food waste represents almost 60% of the total municipal solid waste disposed in the landfill. Material valorisation of food waste usually conducted by biological processes such as composting. Compost, an organic amendment, is the final product of the composting process. These processes are efficient, low cost and environmentally friendly alternative for managing food waste and are used extensively worldwide. Therefore, organic solid waste management practices program for the communities in Perlis was conducted. The main objective of this program was to instilling environment awareness especially among Perlis citizens. This study was investigated the impact of food waste or kitchen waste composting to the citizens in Perlis State and the beneficial of compost fertilizer to our environment especially in plant growth. Composting method was taught to the food premises owner, individuals, teachers, and students and their responses to the composting practices were then summarized. In future, we can prolong our landfill lifespan by practicing organic waste composting and can preserving our environment.

Municipal Organic Solid Waste

The experiment was conducted with the objective of providing more information on the physiology and rumen microbial ecology of goats fed municipal organic solid waste treated with Diastic microbes of snails (Achatina achatina). The study was on the treated and untreated municipal organic solid waste as components of experimental diet. Balanced rations containing diets; A = 45% untreated municipal organic waste (UMOW), B = 45% treated municipal organic waste (TMOW), and C = 70% treated municipal organic waste (TMOW), with wheat offal, palm kernel cake, and molasses used to balance the diets. Where grass/legume ratio of 3 parts of Panicum maximum and 1 part of Centrocema were fed across treatments at the same proportion. The three rations were fed to 18 unsex Red Sokoto goats aged between 6 to 7 months, with an average weight of 8.01±2.50kg. They were housed in pens, on a floor space of 0.5 to 0.75m2 in a completely randomized designed experiment replicated six times and fed for a period of 52 days. The results were separated according to the parameters of rumen physiology (pH, total volatile fatty acids, acetic, propionic, butyric acids and ethanol, and rumen ecology (bacteria, protozoa, and fungi, which are mainly anaerobic microbes). The investigations revealed that microbial (bacteria, protozoa and fungi) load counts were significantly (p<0.05) influenced by dietary treatments. While the total volatile fatty acids (TVFA), acetic, butyric and propionic increased (p<0.05) except for the TVFA and the propionic acid that showed numerical (p>0.05) increased levels of (TMOW). The pH levels improved (p>0.05) between 6.7 to 6.8 where the rumen electrolytes (Ca, Na and K) increased (p<0.01) with increased levels of TMOW. Rumen moisture, dry matter and fat content were (p<0.01) influenced by TMOW diets while ash content was (p<0.01) influenced by the TMOW. Crude protein, ether extract, crude fibre and carbohydrate were not affected (p<0.01; p<0.05) affected. It is good to note that, the microbial community of snail used in the pre-feeding fermentation of municipal organic waste had influence in the physiology and rumen microbial ecology at interface with the goat, enhanced improved the organic matter degradation and feed quality, of the highly fibrous municipal organic solid waste.
