ReWasCO liquid soap

The recycling rate of waste cooking oil (WCO) in Malaysia is estimated to be lower than paper, plastic, and glass. Therefore, ReWasCO was an innovative WCO liquid soap product as an alternative to reduce domestic WCO in the country. The novelty of this innovation project, the preparation process of this ReWasCO liquid soap was 100% using WCO, whilst the available formulation requires a mixture of oils, including the new oil for preparing WCO liquid soap. In addition, this project used a mixture of tropical plants such as pandan and kaffir lime leaves which are not widely commercialized. Then, a study of consumer acceptance of the final product produced was performed. Overall, 92% of the consumers rated this product as"good" and “very good”. Regarding costing, ReWasCO liquid soap could save around 273% of money compared to the commercially available soap which aligned with the country's aspirations of creating a prosperous society: money saving and minimising environmental pollution.
