Waste Processing

Recycling of organic wastes is an extremely important and challenging environmental task. One of the promising trends in this field is the creation of multi-mode (combustion, pyrolysis and gasification) plants for processing organic wastes with production of such useful products as thermal energy and energy carriers (biocoal, bio-oil, pyrolysis resins, synthesis gas, etc.) and fertilizers. When creating such plants, the main problems include instability of the properties of a source material, its high water and ash content. This drives the developers to use non-standard equipment and atypical control algorithms, the creating of which requires a lot of experimental work to be done. At the same time, conducting field experiments is an expensive, difficult and long process that highlights the need for extensive use of mathematical and computer modeling. In this paper, mathematical models of elements of the gas-air path of the organic waste processing plant are obtained. The characteristics of the gas-air path of the plant as of an object of regulation for pressure in the lower and vacuum in the upper part of the combustion chamber are determined. The gas-air flow consists of the flue and the air ducts and serves to remove flue gases from the combustion chamber and supply air needed to maintain fuel combustion. When developing new automation systems, modeling allows assessing the applied solutions accurately, simplifying and reducing the cost of their development, solving the problems of system stability, optimizing transient processes, etc. The nonlinearity of the obtained mathematical models on the "the pressure at the inlet to the n-th section air-gas flow path — the pressure at the outlet of the n-th section of the air-gas flow path" channels, the nonstationarity of objects of control and dependence of their dynamic characteristics on operating mode of the plant are determined. Due to developed models, the two-way relationship of the gas and air paths has been revealed. When modeling, the gas-air flow of the plant is divided into several sections for which the mathematical models are obtained. They are required to synthesize controllers of flue gases vacuum in the upper part and the air pressure in the lower part of the combustion chamber.

Intermediate Level Radioactive Waste

The solid waste plant at Harwell in Oxfordshire, contains a purpose built facility to input, assay, visually inspect and sort remote handled intermediate level radioactive waste (RHILW). The facility includes a suite of remote handling cells, known as the head-end cells (HEC), which waste must pass through in order to be repackaged. Some newly created waste from decommissioning works on site passes through the cells, but the vast majority of waste for processing is historical waste, stored in below ground tube stores. Existing containers are not suitable for long term storage, many are already badly corroded, so the waste must be efficiently processed and repackaged in order to achieve passive safety. The Harwell site is currently being decommissioned and the land is being restored. The site is being progressively delicensed, and redeveloped as a business park, which can only be completed when all the nuclear liabilities have been removed. The recovery and processing of old waste in the solid waste plant is a key project linked to delicensing of a section of the site. Increasing the operational efficiency of the waste processing plant could shorten the time needed to clear the site and has the potential to save money for the Nuclear Decommissioning Authority (NDA). The waste processing facility was constructed in the mid 1990s, and commissioned in 1999. Since operations began, the yearly throughput of the cells has increased significantly every year. To achieve targets set out in the lifetime plan (LTP) for the site, throughput must continue to increase. The operations department has measured the overall equipment effectiveness (OEE) of the process for the last few years, and has used continuous improvement techniques to decrease the average cycle time. Philosophies from operational management practices such as ‘lean’ and ‘kaizen’ have been employed successfully to drive out losses and increase plant efficiency. This paper will describe how the solid waste plant at Harwell has continuously increased the throughput of RHILW, which should lead to significant programme savings.

Blockage of septic tanks is one of the problems in the community related to the discharge of toilet waste produced. The use of synthetic toilet cleaners that are not environmentally friendly is one of the factors that can inhibit the process of decomposing organic waste. The existence of microbial killer ingredients in toilet cleaning materials that come into the septic tank will actually inhibit the growth of essential microbes that play a role in the perfection of the decomposition process. Lack of understanding of the community related to microbial processes in the processing of toilet waste is one of the factors inability of the community to overcome these problems. This community service aims to disseminate information related to the processing of organic waste, the role of microbes in the processing of toilet waste, how to make microbial formulas that play a role in the processing of toilet waste, as well as efforts to increase the creativity of the community to process their own waste to improve environmental sanitation and improve community welfare. The results of the training showed that the average pretest and post test scores of the cadres of Tenggilis Surabaya village experienced a significant increase in value with a mean value of 37.78 (pretest) to 62.22 (post-test). Toilet waste processing cadres have been able to make biotoilet products that can be used to process limbat toilets in their homes. The informationand insights they receive can be passed on to the community from each cadre.AbstrakPenyumbatan septic tank merupakan salah satu permasalahan di masyarakat terkait dengan buangan limbah toilet yang dihasilkan. Penggunaan pembersih toilet yang berbahan sintetik yang tidak ramah lingkungan merupakan salah satu faktor yang dapat menghambat proses penguraian limbah organik. Keberadaan bahan pembunuh mikroba dalam bahan-bahan pembersih toilet yang ikut masuk ke dalam septik tank justru akan menghambat pertumbuhan mikroba esensial yang berperan dalam kesempurnaan proses dekomposisi. Kurangnya pemahaman masyarakat terkait dengan proses mikroba dalam pengolahan limbah toilet merupakan salah satu faktor ketidakmampuan masyarakat dalam mengatasi permasalahan tersebut. Pengabdian masyarakat ini bertujuanuntuk mensosialisasikan informasi terkait proses pengolahan limbah organik, peran mikroba dalam pengolahan limbah toilet, cara membuat formula mikroba yang berperan dalam pengolahan limbah toilet, serta upaya meningkatkan kreativitas masyarakat untuk mengolah limbahnya sendiri guna meningkatkan sanitasi lingkungan dan meningkatkan kesejahteraan masyarakat. Hasil pelatihan menunjukkan bahwa rerata nilai pretest dan post test kader kelurahan Tenggilis Surabaya mengalami peningkatan nilai yang cukup signifi kan dengan rerata nilai dari 37,78 (pretest) menjadi 62,22 (post test). Kader pengolahan limbah toilet telah mampu membuat produk biotoilet yang dapat dimanfaatkan untuk mengolah limbat toilet di rumah masing-masing. Informasi dan wawasan yang mereka terima dapat di teruskan kepada komunitas asal masing-masing kader.

High percentage of organic waste in urban areas makes composting as good alternative in waste processing. However, composting has not been effectively used and the result is not optimal. Previous studies found compost can be used as biocover media to reduce methane emission landfill. The objective of the study is to identify the characteristic of produced at temporary waste unit Depok, West Java and the effect of compaction toward the amount of methane removal in the landfill. Before applied as biocover media, compost was characterized followed by maturation process. Study on methane removal efficiency was conducted as batches in four reactors for 35 days with compaction rate varying from 750, 800, 850 dan 900 kg/m3. Composting media used in the research had 80 cm thickness with artificial gas consisting of 50% CH4 dan 50% CO2. Initially, compost did not meet criteria as mature compost based on SNI 19-7030-2004, and as media biocover hence a pre-treatment was needed to improve the quality compost to meet the requirements. Compaction rate of 900 kg/m3has highest elimination capacity of methane i.e. 98,31%±3,6% and 13,98±4,32 g/m3/hour.
