KCS takes its first steps into R&D – WCO - WCO News
The first R&D programme conducted by KCS in its 50-year history, CustomsLab is a four-year programme scheduled to run from 2025 to 2024. It comprises a total of seven research projects, five of which were launched in June 2025, with two more set to begin by June 2025. A group of senior scientists was established for the overall management of

Plasticizers – Benefits, Trends, Health, and Environmental Issues
Plasticizers are produced by a reaction of an alcohol with an acid such as adipic acid, phthalic anhydride, and so forth. The choice of alcohol and acid will determine the type of ester that can be produced and hence the kind of plasticizer.
- Can WCO be used for preparing internal plasticizer?
- However, WCO can be used for the preparation of fine chemicals such as internal plasticizer. With this aim, this work is focused on preparing internal plasticizer by using WCO and determining technical viability of non-migration poly (vinyl chloride) (PVC) materials.
- What is a renewable plasticizer?
- A renewable plasticizer originated from waste cooking oil (WCO) was developed. The ester and double bonds in WCO was converted to the epoxy groups. The developed plasticizer showed better compatibility with PVC. The plasticizer significantly improved the stability and flexibility of PVC.
- Is WCO a viable replacement for petroleum based plasticizers?
- WCO has also been effectively used for the production of plasticizers and used as additives in the plastic industries, food packaging and toys manufacturing. Increased demand for plasticizers in the last decade and the negative effects of petroleum-based plasticizers has made the search for a viable replacement inevitable.
- Can WCO be used as a plasticizer for PVC?
- As an alternative, WCO is regarded as a good resource instead of edible oil to produce plasticizers for PVC, especially in some developing areas. Similar to structural modification of vegetable oil, reducing the degree of the –C C- unsaturation is still the main approach [Jia et al., 2018; Zheng et al., 2018; Feng et al., 2018].
- How are WCO-based plasticizers synthesized?
- Most WCO-based plasticizers were synthesized by a conventional epoxidation approach, where the –C C- bond was converted to the epoxy group with the assistance of peroxy acid. Compared with internal oxirane, the terminal epoxy group in plasticizer enhanced the plasticizing effect and thermal stability of PVC [Chen et al., 2017].
- Does epoxidized WCO plasticizer provide better compatibility with PVC?
- While the production of epoxidized WCO plasticizer was reported, very limited information was available on the introduction of epoxy groups to the ester bond in WCO. It is expected that WCO-based plasticizer with a higher epoxy value could provide better compatibility with PVC.
