Status Analysis

Large amounts of industrial hazardous waste (IHW) are generated with the rapid economicgrowth in Chongqing Municipality. The generation of IHW was 355994.12t in 2010 and made up 1.25% of industrial solid waste (ISW). Huge varieties and complex components of IHW make it difficulty in its management, which causing serious environmental problems. In this paper, the status of IHW generation, disposal and management was analyzed from 2006 to 2010. Moreover, the pollution prevention measures are proposed for the purpose of protecting the ecological environment

In HCMC, there are 958 factories in 12 industrial parks – export processing zones (IP-EPZ) (2006), 1,011 large factories, 6,202 small and medium factories out of IP-EPZ with 24 various industries. More than 700 factories operate in field of buying and recycling solid waste. Besides, there are 21 licenced and series of unregistered factories operating in field of collecting, transporting, treating, and burning industrial solid waste - hazardous waste (ISW-HW). There is the survey deployed in 24 districts (HCMC). The scope of that inquiry is 278 factories in IP-EPZ, 96 large factories, 1,142 small and medium factories out of IP-EPZ. The quantity of industrial solid waste is 1,044 tons per day with 12 percent of hazardous waste. After analysing the advantages and disadvantages of 05 methods used for predicting the quantity of ISW-HW, according to the ability of collecting data related in HCMC, the research has compared and chosen the best method. The results are: 1,641 tons per day (2010); 3,196 tons per day (2015); 7,318 tons per day (2020). With more and more ISW-HW, doing overall researches in order to establish the effective ISW-HW management measures in HCMC, minimize the negative impacts to environment and public health.

Solid Waste Treatment

Survey results in 72 mechanical manufactures in Ho Chi Minh City, in conjunction with related studies show that the charge of industrial solid waste – hazardous waste treatment is operated in two forms: fixed or progressive based on the generated volume. Price of collection - transportation - storage - treatment - landfill for each waste composition is widely varying (5-20 times), depending on the agreement between production facilities and service units. Price is not yet able to handle the relationship with the treatment technology, treatment level to be achieved as well as the correlation to the transported distance and the extent of hazardous waste. Methodology for calculating the costs of industrial solid waste treatment by burning method is initially set. Treatment costs per ton of industrial solid waste of the mechanical industry are determined. The formulas are specifically built for each case of emissions, corresponding to different levels of load transportation.

Golden Horn

The pollution in the Golden Horn is one of the most important environmental problems of Istanbul. Alluvium carried by Alibey and Kagithane creeks, and domestic and industrial wastewater discharges are the major sources of the pollution. In the upstream, a part of 3 to 4 km long is almost completely filled with debris and organic solids. There is a high anaerobic activity in the sediment resulting in a heavy odor problem. Sea traffic is impossible since the depth of water is less than 10 cm at this part. A restoration feasibility project has been carried out for pollution prevention and evaluation of the restoration alternatives. For this purpose, first, characteristics of water quality and bottom sediment were determined. Second, pollution prevention measures and the alternatives for the dredging and disposal of the bottom sediment were evaluated. Istanbul Metropolitan Municipality has already started the dredging work by early 1997, and has completed the diversion of all domestic and industrial wastewater discharges out of the Golden Horn. This paper summarizes the studies for determining current status, evaluating the restoration alternatives, and also the progress of the on-going dredging work.

A review on the sources, current status and related disposal technology of industrial hazardous waste (IHW) in domestic and overseas. The diverse and complicated sources of current solid waste were analyzed. Based on the current researches on the disposal technology and management of IHW, approaches for the development of the solid waste disposal technology was recommended. According to this research, the government should increase the investment to introduce advanced disposal technology and management from abroad, and improve the level of disposal facilities.

It is suggested that industrial solid waste has a wide variety of types. It has complex composition and huge amount, which is proved to be one of the main sources of environment contamination. The damage degree to the environment of industrial solid waste is as dangerous as water pollution and atmospheric pollution. Based on the severe circumstance of industrial solid waste in a worldwide range, this article aimed to describes the definition, classification and the status of disposal, comprehensive utilization and discharge of industrial solid waste in China. And from the view of engineering, puts forward some countermeasures for industrial solid waste disposal - one-stop harmless disposal technology.

The Status

The Basel Convention (1989) and Rio Summit (1992) were two major instances to tackle with the main issues on Hazardous Waste. The first one is the mechanism to control the illegal traffic of hazardous waste, and to promote an Environmental Sound Management for the overall waste cycle. On the other hand, Rio Summit launched a renewed interest on regulatory environmental instruments for pollution prevention, control and mitigation of environmental damages generated by industrial activities. Among them, one of the major challenges is related to the hazardous waste management. In Latin America, as well as in the rest of the world, the theme has been considered mainly through the environmental regulations, pushing the enterprises to look for different solutions to face the high costs involved in the production processes. In this paper, a comparative assessment was made of the hazardous waste management in four Latin American oil-producing countries. The specific environmental regulations adopted are reviewed, to show the status of present environmental policies and legal measures to promote reuse, recycle, recovering and reduction of hazardous materials and wastes. Coincidential provisions are reported, as well as the differences in the legal approach, which is a clear signal of the efforts made in environmental regulations, trying to control and prevent the pollution generated by industries.

Co2 Mineralization

CO2 mineralization (aka mineral carbonation) is a promising method for the chemical sequestration of CO2 via reaction with oxides of alkaline or alkaline-earth metals to form carbonates. It has documented advantages over similar technological solutions to climate change. The huge amount of industrial solid waste, as a serious environmental issue confronted by China, can provide additional alkalinity sources for CO2 mineralization. In this study, we present an overview of the latest advances in the emerging technologies of CO2-mineralization via industrial solid waste in China, from the perspective of both theoretical and practical considerations. We summarize the types of industrial solid waste that are used (mainly coal fly ash, steel slag, phosphogypsum, and blast furnace slag) and the technological options available in the literature, with an emphasis on the discussion of the involved process-intensification methods and valuable chemicals produced. Furthermore, we illustrate the current status of pertinent policies, and research and development activities in China. Finally, we identify the current knowledge gaps, particularly in understanding the overall sustainability performance of these CO2-mineralization technologies, and indicate that the technical, economic, and environmental challenges of promoting and commercializing these technologies for the co-utilization of industrial solid waste and carbon resources call for, amongst other things, more joint efforts by chemists, chemical engineers, and environmental scientists, and more feedback from the energy and industrial sectors.
