Biological Transformation

The composting of organic waste is an alternative waste management technique that can be used to control the increase in waste generation. The objective of this study was to identify a type of effective microbes (EMs) that accelerate the composting process. The study also determined the suitability of using a KompostKu rotary composter along with additional materials such as coconut husks and Takakura EMs for composting food waste from the Universiti Kebangsaan Malaysia (UKM), and determines the economic value of the compost. In order to select the most efficient EMs, Takakura and fruit waste EMs were prepared and used during the composting of both food and yard waste using a composter barrel. Four important parameters were examined to ensure the effectiveness of the process, including temperature, moisture content, potential of hydrogen (pH), and carbon to nitrogen (C/N) ratio. The experimental results revealed that Takakura EMs were superior to the fruit waste EMs in accelerating the composting process. The use of coconut husks as an absorbing agent with Takakura EMs also accelerated the composting process, requiring approximately four weeks to fully decompose the food waste. It was estimated that the composting of food and landscape waste at the UKM could annually generate compost products worth over 30,660 Malaysian Ringgit (MYR). The use of Takakura EMs enhanced and accelerated the composting process and provided high-quality compost

The Impact

One way to improve compost quality of typical organic waste is by addition of additive such as wood chips. This study aims to analyze the impact of the wood chips addition (ratio 1:10) on compost quality of typical organic waste (fruits, vegetables, yard waste, and food waste) in home composter, and to compare the compost quality with the standard of domestic compost according SNI 19-7030-2004. Analysis was conducted on composts raw material, compost maturity process in every 5 days measurement, and on compost product. Analysis of compost product of typical organic waste with addition of wood chips showed that parameters of temperature, moisture content, and pH of vegetables and yard waste has complied the standard whilst parameter of C/N ratio has not complied. The addition of wood chips caused the drop of compost temperature and moisture content, resulted in the decomposition process located in aerobic condition, resulted in production of compost in form of humus in greater volume. The addition of wood chips also caused the compost pH and C/N ratio increased.Keywords: compost quality, home composter, typical organic waste, wood chipsAbstrakSalah satu upaya untuk memperbaiki kualitas kompos sampah organik adalah dengan penambahan bahan aditif, seperti serpihan kayu. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serpihan kayu (perbandingan 1:10) terhadap kualitas kompos sampah organik sejenis (buahan, sayuran, halaman dan sisa makanan) dalam komposter rumah tangga dan membandingkan kualitas akhir kompos ini dengan kualitas kompos sampah domestik menurut SNI 19-7030-2004. Analisis dilakukan terhadap bahan dasar kompos, proses kematangan dengan pengukuran setiap lima hari sekali, dan kualitas akhir kompos. Dari analisis akhir kualitas kompos sampah organik sejenis dengan penambahan serpihan kayu, parameter yang telah memenuhi standar adalah temperatur, kelembapan, pH untuk sampah sayuran dan sampah halaman, sedangkan untuk parameter rasio C/N belum memenuhi standar. Penambahan serpihan kayu menyebabkan temperatur dan kelembaban kompos menurun, sehingga proses dekomposisi berada pada suasana aerobik, yang menghasilkan kompos dalam bentuk humus dengan volume yang lebih banyak. Penambahan serpihan kayu juga meningkatkan pH dan rasio C/N kompos. Kata kunci: komposter rumah tangga, kualitas kompos, sampah organik sejenis, serpihan kayu

The composition of organic waste reaches 59% of the total municipal solid waste in Indonesia. One way to process organic waste is composting by utilizing microorganisms to break down waste into compost. Naturally, the composting process took a long time but can be accelerated by adding microorganisms to the activator. This study analyzes the quality and quantity of compost using the Biopore Infiltration Hole (BIH) method with activator addition. Composting was duplicated in the yard area with clay soil type and water infiltration rate of 0,3 cm/hour. The BIH was made in a 10 cm diameter, a 100 cm depth, and the distance between the holes was 50 cm. Composting variations consist of variations in the composition of the raw materials and the activators' uses. Variations in the raw material composition consisted of 100% yard waste, 100% food waste, 50% yard waste and 50% food waste, and 70% food waste and 30% yard waste. In contrast, the activator variations consisted of no activator, EM4 activator, and Stardec activator. Compost analysis consists of maturity, quality of physical and macro elements, and quantity of compost. The results showed that all variations of composting had met the standard of maturity and quality of physical and macro elements according to SNI 19-7030-2004. The addition of activator affected composting time and compost quantity. The composting time in BIH with activator ranges from 41-60 days. In BIH without activator ranges from 65-75 days, there was a reduction in composting time by 15-25 days with the activator addition. However, the activator addition caused reducing the compost quantity by 10-20%. The selection of compost variations by scoring results in compost with a composition of 50% yard waste and 50% food waste and the addition of Stardec activators was the best variation in terms of compost maturity, quality, and quantity.

AbstractTo tap the organic waste generated onboard cruise ships is a very promising approach to reduce their adverse impact on the maritime environment. Biogas produced by means of onboard anaerobic digestion offers a complementary energy source for ships’ operation. This report comprises a detailed presentation of the results gained from comprehensive investigations on the gas yield from onboard substrates such as food waste, sewage sludge and screening solids. Each person onboard generates a total average of about 9 kg of organic waste per day. The performed analyses of substrates and anaerobic digestion tests revealed an accumulated methane yield of around 159 L per person per day. The anaerobic co-digestion of sewage sludge and food waste (50:50 VS) emerged as particularly effective and led to an increased biogas yield by 24%, compared to the mono-fermentation. In the best case, onboard biogas production can provide an energetic output of 82 W/P, on average covering 3.3 to 4.1% of the total energy demand of a cruise ship.

Using organic wastes as agricultural amendments is a productive alternative to disposal in landfills, providing nutrients for plant growth and carbon to build soil organic matter. Despite these benefits, a large fraction of organic waste is sent to landfills. Obstacles to the adoption of wastes as sources of plant nutrients include questions about harmful effects to crops or soils and the wastes’ ability to produce satisfactory yields. We compared six organic waste amendments with a mineral fertilizer control (CN) to determine effects on soil quality, soil fertility, crop quality, and crop yield in 2013 and 2014. Waste amendments were applied at a rate sufficient to supply 10,000 kg organic C/ha over two seasons, and mineral fertilizer was applied to control plots to provide 112 kg-N/ha/yr. The experiment was laid out in a randomized block design with four replicates and three crops: sweet corn (Zea mays L. cv. Applause, Brocade, and Montauk), butternut squash (Cucurbita moschata Duchesne cv. JWS 6823), and potatoes (Solanum tuberosum L. cv. Eva). Amendment with biosolids/yard waste cocompost (BS), dehydrated restaurant food waste (FW), gelatin manufacturing waste (GW), multisource compost (MS), paper fiber/chicken manure blend (PF), and yard waste compost (YW) did not have a negative impact on soil moisture, bulk density, electrical conductivity (EC), or the concentration of heavy metals in soil or plant tissue. Our results indicate potential uses for waste amendments including significantly raising soil pH (MS) and increasing soil organic matter [OM (YW and BS)]. The carbon-to-nitrogen ratio (C:N) of waste amendments was not a reliable predictor of soil inorganic N levels, and only some wastes increased potentially mineralizable nitrogen (PMN) levels relative to the control. Plots amended with BS, FW, and GW produced yields of sweet corn, butternut squash, and potatoes comparable with the control, whereas plots amended with YW, PF, and MS produced lower yields of sweet corn, squash, or both, although yields for potatoes were comparable with the control. In addition, the marketability of potatoes from PF plots was significantly better than that of the control in 2014. None of the wastes evaluated in this study had negative impacts on soil properties, some provided benefits to soil quality, and all produced comparable yields for at least one crop. Our results suggest that all six wastes have potential to be used as sources of plant nutrients.

North America is a big consumer and consequently a big producer of waste. For the purpose of this project, we were primarily interested in collecting information in North America, focusing on Quebec primarily. The main research question was risen up during the fieldwork and assistance with the Canadian company. It clearly presents the enterprise readiness for obtaining a smart solution on organic/food waste problem. It is believed, how organic/food waste can be a resource of a high value. There is a capacity of creating a new path, where organic/food waste could become the important as plant/field nutrient supply. The circular approach to organic waste management is urgently needed in a way how the organic waste should be reduced and returned as productive resource input into our economy. The paper presents a new value towards a sustainability process that Canada is building at the moment. It represents the innovative approach, which is highly accepted in some cities in Quebec with the obtained pilot projects and excellent results. This paper is not only a simple research paper, but it is also the very important original innovative document which can be highly used on the level of each municipality, region and federal level.
