The paint waste from the cosmetics packaging industry was sent to the third party for disposal by paying several management fees for hazardous waste. The use of paint waste as raw material for paving block products can reduce the environmental impacts and provide economic benefits. The life cycle assessment is a tool for measuring the environmental impact of this utilization compared to the management carried out by the third party. There are four scenarios reviewed that consist of third-party management, utilization as raw materials for paving block by the concentration of 1, 2, 3, 4 and 5% respectively. The analysis shows that the utilization of dry paint waste as a raw material for a paving block can reduce the impact of global warming and photo oxidant. The compressive strength value of paving blocks increased with the addition of the dry paint waste with the concentration of 1 and 2%, then a slight decrease in proportion occurred with the addition of paint waste concentration up to 5%. The addition of dry paint waste does not affect the water absorption with a range of 2%, meeting the standard for a paving block.
The waste generation of the plastic packaging industry for the cosmetic product is consisting of the hazardous and non-hazardous waste. The non-hazardous waste of cosmetic product includes product reject, plastic bags, cardboard, and paper. The content of hazardous waste of the cosmetic product is the part such as chemical packaging drum, paint sludge, and wastewater treatment sludge. On the other hand, there is a chance of the waste management that can be started from the segregation of both hazardous and non-hazardous waste, recycling of non-hazardous waste and utilization of waste into products by third parties. That is because the dangerous waste that is carried out according to the waste regulation can be used as a useful product to provide economic and environmental benefits. The research examines various opportunities to use waste as raw material and also to be processed into products. The study steps consist of identification, assessment, techno-economic analysis, and implementation approaches. The study results show that the hazardous solid waste can be used as fuel, filling materials for paving blocks, and ceramic raw materials. The utilization as raw material for paving blocks shows the most significant opportunity for economic and has environmental benefits.
Small and medium scale electroplating industry produces a variety of plating products by using hazardous substances as raw materials. The production process at SMI electroplating held manually. Industrial environmental management is conducted by implementing clean production starting from waste prevention, reduction and recycling. Research is conducted in the field through observation and review of actions to reduce process failures and improve them. The success of implementing clean production as an environmental management effort can be extended to other SMIs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
