Growth Net Zero Roadmap

PT Growth Asia commits to Net Zero greenhouse gas emissions across Scope 1, 2, and 3 of our entire value chain by 2050, decoupling production growth from carbon footprint as we supply the global mining and industrial sectors.

Executive Summary

Casting a sustainable future

As a cornerstone of the Growth Steel Group and a leading supplier of wear-resistant ferrous and composite liners with grinding media solutions, PT Growth Asia recognizes its profound responsibility to the environment. Operating from the Medan Industrial Estate in North Sumatra, our reach is global — and so is our environmental impact.

This roadmap outlines our strategy to ensure the products we supply to Asian, Australian, American, African, and European markets are manufactured sustainably.

“

To pioneer sustainable operations in Southeast Asia by transitioning our metallurgical processes, embracing renewable energy, and driving circularity within our supply chain.

Net Zero Vision Statement
Target Trajectory

Emissions reduction pathway

Interim science-based targets for Scope 1 & 2, aimed at halving operational emissions before mid-century.

2025
Baseline finalization & optimization — 100% baseline
2030
Renewables & efficiency integration — 30% reduction
2040
Next-gen smelting & electrification — 75% reduction
2050
Full Scope 1, 2 & 3 mitigation — Net Zero
Carbon Footprint

Emissions across three scopes

Addressing emissions specific to our heavy-industrial operations.

Scope 1

Direct emissions

Source

On-site fuel combustion, natural gas for heat treatment, fleet vehicles, metallurgical emissions from casting.

Mitigation focus

Electric heat treatment, green hydrogen/biogas alternatives, fleet electrification.

Scope 2

Indirect emissions

Source

Purchased grid electricity (PLN) powering induction melting furnaces and plant operations, including lighting.

Mitigation focus

Expanded green power plant capacity, renewable PPAs, on-site solar PV installations.

Scope 3

Value chain emissions

Source

Extraction of raw materials (alloys, additives), global shipping and freight, end-of-life treatment.

Mitigation focus

Low-carbon raw material sourcing, increased scrap steel usage, green logistics partnerships.

Strategy

Four pillars of decarbonization

01

Process Electrification & Energy Efficiency

Upgrading induction furnaces to best-in-class efficiency, optimizing melt times and ladle insulation, recovering waste heat from casting. Rubber composite and grinding media facilities maximize recovered steam and alternate energy sources.

02

Renewable Energy Integration

Maximizing green energy from our biomass power plant and rooftop solar deployment. Securing long-term renewable energy certificates and green power contracts across wind, solar, and geothermal sources.

03

Circular Economy & Material Stewardship

Increasing recycled buy-back scrap steel to reduce demand for carbon-intensive virgin material. Strict waste-recycling protocols and sand reclamation in the molding section.

04

Supply Chain & Scope 3 Engagement

Collaborating with maritime freight partners on lower-carbon shipping fuels and optimized routes. Strict ESG criteria imposed on metallurgical suppliers for ethical, sustainable sourcing.

Implementation Timeline

Three phases to 2050

01
Mobilization
2025–2030
  • Third-party audit of Scope 1, 2, and 3 baseline emissions
  • Install Phase 1 of on-site Solar PV microgrid
  • Increase scrap utilization in ferrous castings by 15%
02
Acceleration
2031–2040
  • Partial retirement of fossil-fuel heat treatment ovens
  • Majority of Scope 2 electricity from renewables
  • Advanced carbon capture / alternative reductants, where viable
03
Finalization
2041–2050
  • Full decarbonization of inbound & outbound logistics fleet
  • Certified carbon removal offsets for residual emissions
  • 2050: declare fully verified Net Zero operations
Governance

Sustainability & Decarbonization Committee

Reporting directly to the Board of Directors of the Growth Steel Group. Responsible for tracking green technology capex, monitoring the Quality Control Circle for energy efficiency, and tying sustainability metrics to executive performance evaluations.

Reporting

Transparent, GRI-aligned disclosure

Starting in 2026, PT Growth Asia will publish an annual Sustainability Report aligned with the Global Reporting Initiative (GRI), monitoring emission reduction targets to keep the roadmap on track for Net Zero in 2050.
