Abstract – Textile industry is one of the waste contamination industries that can pollute the environment, so that the rapid development of textile industry must be followed by the improvement of its sewage treatment system. Along with the global issue of Green Manufacturing, the textile industry waste treatment can promote environmentally friendly waste treatment process and derived from renewable substances. Therefore, it is necessary to study the utilization of rice husk silica in the processing of textile waste. The results of the study provide information that textile wastes come from all processes in the textile industry, from pretreatment to finishing. Rice husk ash silica is a material utilized adsorption of textile waste or mixture of PolyVinylChloride (PVC) membrane material to filter textile waste. The characteristics of rice husk silica are influenced by the extraction method. The initial washing process using acid and then combustion at 600 ° C - 750 ° C produces a relatively high purity of silica with a maintained silica amorphous level.Keywords: Rice Husk Silica, Textile Waste, Textile Waste Processing, Silica Characteristic

The life of a modern person today cannot be imagined free from an urgent and urgent problem – the problem of waste recycling. At the same time, the environmental situation in large cities, including industrial enterprises, is mainly determined by the state of the waste treatment system. These include solid municipal waste, as experts call the garbage that is formed daily in everyday life and makes a long way from the garbage chute to the yard container and further to the city dump.At the moment, the infrastructure for collecting and processing secondary raw materials (glass, plastic, paper, batteries, etc.) is developing on the territory of many CIS countries, including Russia, while there are no reception points for textile waste of production and consumption in sufficient quantities, unlike in European countries. There are retail outlets that accept unnecessary textiles from the population, and in return provide discounts on their products. However, taking into account the volume of textile waste generation (about 4.2–4.8 million tons per year), the existing textile waste collection system, which collects only about 0.4% of textile waste, is clearly insufficient. Based on the identified problems, the authors of this article give a socio-ecological and economic assessment of the problem of handling textile waste of consumption in Russia. The analysis of the relationship of the problems of textile waste management to the UN Sustainable Development Goals is carried out. The international experience of applying the principles of the closed-cycle economy in relation to textile waste is considered and recommendations for the transition of the Russian textile industry to a closed-cycle economy are formed.

Wastewater reclamation and reuse have become an alternative to saving operational costs while reducing the impact of waste pollution. In this paper, integration of electrocoagulation (EC) and polysulfone-based ultrafiltration (UF-PSf) membranes were used for the mentioned purpose. The EC unit equipped with 7 (seven) pieces of E-shaped of Al electrodes, which operated at a current of 3 (three) Amperes and a residence time of 2 (two) hours. The waste samples obtained from textile and oil palm industries. The experimental results were compared based on product quality and economic feasibility. When used for textile waste treatment, the integrated EC-UF units reduced TDS, TSS, BOD, and COD by 77%, 95%, 70 -80%, and 60-70%, respectively. While in palm oil waste treatment, the TDS and TSS reduced by 92% and 98%. The electrode loss rate in palm oil waste treatment was 2 (two) times greater than textile waste. By assuming that the waste production capacity of both industries was 400 m3/day, the water production cost in textile waste treatment was Rp. 4,000/m3. While in the palm oil waste treatment, the water production cost was Rp. 6,000/m3. These results showed that the EC-UF unit could be used as an economical and environmentally friendly alternative process for reclamation of industrial wastewater that meets the clean water quality standards.

This research was conducted for the purpose to overcome Indonesia waste problem. The samples are classified into garden waste, paper waste, wood, food waste, and MSW with objective to identify which type of waste give out more syngas since there is waste separation in Indonesia. All samples were treated by plasma gasification without pre-treatment (drying). Arc plasma torch used in this experiment was made by National Nuclear Energy Agency (BATAN) and used Argon as the gas source. Then the torch was connected to self-designed gasification chamber and gas washing system before injected into a gas bas for composition analysis. Another objective is to identify factors that may affect the gasification efficiency and the experiment shows that moisture content is not really affecting the efficiency but the duration of the process. The mass reduction of each samples were recorded, then the gas produced from the gasification process were analyzed. The result shows that food has the highest mass percentage reduced and producing the highest amount of hydrogen amongst other samples. However, treating MSW also produce considerably high amount of hydrogen. In conclusion, MSW direct treatment (without separation) using plasma gasification is feasible since it still produces desirable quality of syngas.
