ABSTRACT The waste's production rate in Sidoarjo Regency is estimated at 1,216 tpd. Around 464 tpd (ton per day) are transported to Jabon Landfill, and about 298 tpd are treated at the Integrated Garbage Treatment Center (TPST), 3R Treatment Center, and the Bank of Garbage. Therefore, there are still 454 tpd of waste that has not yet been managed, potentially harming the environment. The still limited garbage service level to be transported to the landfill has made the community take the initiative to process the garbage with incinerators placed at the existing TPST. These incinerators can reduce the waste up to 25% to 30% by weight of the waste that enters the TPST. In this research, ten incinerators were studied in the TPST. From the sample conditions obtained, almost all incinerators were operated below the technical standards required for optimum operation and minimum environmental impact. The combustion temperature is generally below 800 °C, the gas residence time is less than 2 seconds, and there is no turbulence. Therefore, the black smoke often occurs due to incomplete combustion. Air pollution control installations such as cyclones and scrubbers are malfunctioning and rusty due to high temperatures and acidic environments. Incinerator management hardly relies on community contributions. However, it is generally only enough for employee salaries. Furthermore, there is no incinerator maintenance. On the other hand, social conflicts due to incinerator smoke are reported to have not yet occurred because the location of TPST is generally still far from residential areas.

Hal ini berarti masih ada 454 ton sampah yang tidak terkelola dan berpotensi lari ke lingkungan. Masih terbatasnya tingkat pelayanan sampah untuk diangkut ke TPA telah membuat masyarakat berinisiatif mengolah sampahnya dengan insinerator yang ditempatkan di TPST yang ada. Keberadaan insinerator ini mampu mengurangi berat sampah hingga 25% hingga 30% berat sampah yang masuk ke TPST. Melalui penelitian terhadap sepuluh insinerator di TPST, diperoleh kondisi bahwa hampir semua insinerator beroperasi di bawah standar teknis yang dipersyaratkan bagi tercapainya operasi optimum dan minimnya dampak lingkungan. Suhu pembakaran umumnya berada di bawah 800 0C, waktu tinggal gas kurang dari 2 detik dan tidak terjadi turbulensi, sehingga sering terjadi asap yang hitam akibat pembakaran tidak sempurna. Kondisi instalasi pengendalian pencemaran udara seperti cyclone dan scrubber banyak yang tidak berfungsi dan berkarat akibat tidak tahan suhu tinggi dan lingkungan yang asam. Pengelolaan insinerator mengandalkan iuran warga namun umumnya hanya cukup untuk honor pekerja sehingga tidak ada untuk perawatan insinerator. Konflik sosial akibat asap insinerator belum terjadi karena lokasi TPST umumnya masih jauh dari permukiman warga. Kata Kunci:  insinerator, skala kecil, operasi, lingkungan

The present research divulges the different inventory control techniques used small scale cements enterprises operated by small scale entrepreneurs through the assistance of primary data collected from eight small scale cement enterprises operating in SIDCO & SICOP, under DIC (District Industries Center) in District Udhampur of Jammu & Kashmir State. The various inventory control techniques identified and quested for in the research were: Always Better Control (ABC), Economic Order Quantity (EOQ), Material Requirement Planning (MRP), and Just-in-Time (JIT). The results of the ranking table quoted that Economic Order Quantity (EOQ) was awarded first rank by almost all the units representing overall mean score of 1.71, Always Better Control (ABC) was denoted by rank two repressing overall mean value as 2.00, Material Requirement Planning (MRP) was quoted rank three as depicted by its mean ranking (2.25), and Just-in-time (JIT) was accorded rank four (3.71) by almost all the small scale cements entrepreneurs/owners.

Abstract In 2015, the All-China Environment Federation v Dezhou Jinghua Group Zhenhua Corporation Limited case was the first civil environmental public interest litigation (CEPIL) against air pollution in China. Constituting a milestone in the field of air pollution control in China, this case (i) confirms the eligibility of a non-governmental organisation (NGO) to file civil public interest litigations; (ii) discusses remedies for the ecological destruction caused by air pollution; (iii) assesses the ecological and environmental damage using the ‘virtual restoration cost’ method; and (iv) uses public apology as an innovative way for Zhenhua to assume liability. By applying and interpreting several important rules under the Environmental Protection Law of China (EPLC) for the first time, this case sets an example for future CEPILs against air pollution in China.

The Chinese government has implemented a number of environmental policies to promote the continuous improvement of air quality while considering economic development. Scientific assessment of the impact of environmental policies on the relationship between air pollution and economic growth can provide a scientific basis for promoting the coordinated development of these two factors. This paper uses the Tapio decoupling theory to analyze the relationship between regional economic growth and air pollution in key regions of air pollution control in China—namely, the Beijing–Tianjin–Hebei region and surrounding areas (BTHS), the Yangtze River Delta (YRD), and the Pearl River Delta (PRD)—based on data of GDP and the concentrations of SO2, PM10, and NO2 for 31 provinces in China from 2000 to 2019. The results show that the SO2, PM10, and NO2 pollution in the key regions show strong and weak decoupling. The findings additionally indicate that government policies have played a significant role in improving the decoupling between air pollution and economic development. The decoupling between economic growth and SO2 and PM10 pollution in the BTHS, YRD, and PRD is better than that in other regions, while the decoupling between economic growth and NO2 pollution has not improved significantly in these regions. To improve the relationship between economic growth and air pollution, we suggest that the governments of China and other developing countries should further optimize and adjust the structure of industry, energy, and transportation; apply more stringent targets and measures in areas of serious air pollution; and strengthen mobile vehicle pollution control.
