Plastics & Packaging Manufacturing in Johor: Environmental, Effluent & Power Compliance Guide

Plastics products and packaging manufacturing cluster mainly in Desa Cemerlang, Tebrau and Senai — long-established industrial townships that supply critical upstream and downstream packaging support to Johor’s electronics and food-processing sectors. Core processes include injection moulding, extrusion, blown-film and packaging printing. The main compliance challenges are the transient grid disturbance that high-power extruders impose on the network, plus control of volatile organic compounds (VOCs) from the printing line and the wastewater from screen washing.

Where a plant carries out large-scale chemical polymerisation or synthesis of base resins, plastic feedstock and monomers, the project is a First Schedule prescribed activity under the Environmental Quality (Prescribed Activities) (Environmental Impact Assessment) Order 2015 and must obtain EIA approval before construction. Where the plant only carries out downstream physical modification, masterbatch compounding, injection moulding and film packaging, it is generally exempt from EIA — but it must still give the Johor State DOE prior written notification of the works before installing exhaust and printing equipment or building the effluent system.

The periodic cooling discharge from injection and extrusion lines, together with screen-wash water from physical cleaning of printing screens, is the main effluent source for a plastics and packaging plant. The wastewater may carry release agents, trace emulsified oil and pigments, and must pass through effective oil-water separation and chemical coagulation / dissolved-air flotation, governed by the Environmental Quality (Industrial Effluent) Regulations 2009 [P.U.(A) 434/2009]. Where a wet scrubber is used to capture printing-solvent vapour, the saturated scrubbing liquid becomes a high-COD effluent that must also be treated to the applicable Standard A or B limits before discharge.

Printing and surface-finishing use large volumes of solvent-based inks and thinners, and the resulting chemical wastes are regulated by the Environmental Quality (Scheduled Wastes) Regulations 2005 [P.U.(A) 294/2005]. Where the liquid waste is flammable, it must be kept in a dedicated explosion-proof chemical store with strict anti-static and spill-containment design; on-site accumulation must not exceed 20 metric tonnes, and storage is limited to 180 days without prior written DOE approval. Containers are labelled with the generation date, waste code and generator contact, and transfers run through the DOE e-Consignment system to licensed facilities.

Electric extrusion equipment such as injection and blow-moulding machines draws significant inrush current when frequently started and switched, which stresses voltage stability on the public network. Under the Electricity Supply Act 1990 (Act 447), the connection scheme — including the limits below, which TNB references from the UK Engineering Recommendations P28 and G5/4 — is submitted to the Energy Commission (ST) via a PE-signed single-line diagram. For a plastics plant with Maximum Demand between 350 kVA and 1000 kVA, where the application is submitted after 22 November 2024, TNB bears the plinth construction and installation cost of the 11/0.4 kV compact substation (CSU), materially reducing the upfront non-productive capital outlay for small and medium plastics and packaging enterprises.
