Experienced Quality Control Chemist within the plastic recycling industry. Skilled in ASTM/ISO-based laboratory testing, polymer characterisation, extrusion trials, injection moulding, and wastewater treatment analysis. Proven ability to develop and implement SOPs, optimise process parameters, monitor NIR sorting quality, and ensure the consistency of pelletised plastic products. Adept at statistical data analysis, root cause investigation, and delivering high-quality technical reports to support continuous improvement and customer product specifications.
•Developing, implementing, and evaluating laboratory testing methods in accordance with ASTM/ISO standards to ensure the quality of pelletised plastic finished products.
•Collaborating on the formulation and review of Standard Operating Procedures (SOPs) for extrusion, wastewater treatment, and NIR sorting, and laboratory tests such as MFI, DSC-OIT, CLTE, ESCR, impact, tensile, flexural, and film tests on finished goods.
•Conducting injection moulding trials and QC tests on plastic pellets and moulded specimens, applying research findings to develop and update SOPs for extrusion, pelletising, and weighbatching to maintain polymer and additive/antioxidant levels, ensuring consistent quality of recycled plastic pellets for tailored product applications.
•Developing, and monitoring quality control procedures in the NIR sorting, wastewater treatment, and extrusion plant, including sort purity(100L), sink-fraction, moisture, sieve, and MFI tests, and determining material suitability for continuous extrusion and pelletising.
•Analysing and conducting wastewater quality tests (pH, conductivity, TDS, TSS), and jar tests to optimise chemical dosing (flocculant, coagulant, antifoam), assessing contamination in Hydrodyn, and evaluating the treatment efficiency of DAF and MBBR systems for treated-effluent reuse in plastic washing operations.
•Engaging in vital Research and Development (R&D) initiatives, conducting extruder trials to develop and test new polymer blends, and improving existing products to address evolving customer demands and elevate the overall quality of our products.
•Maintaining and meticulously reviewing a statistical database of laboratory test results, instrumental in generating customer product specification reports and facilitating post-job analysis.
•Conducting bale audits and regular inspections of raw materials, in-process materials (regrind), and finished products; issuing NCRs for quality deviations; leading RCA for deviations and quarantined materials; and implementing corrective actions.
