Introduction

Green Steel for MSMEs is becoming an important industrial and business consideration as steel manufacturers face growing pressure to reduce carbon emissions, improve energy efficiency and remain competitive in domestic and international markets.

For smaller and medium-sized steel manufacturers, decarbonisation does not necessarily mean immediately investing in expensive technologies such as hydrogen-based steelmaking. A practical transition can begin with measurement, process improvement, energy efficiency, resource optimization and better engineering decisions.

The objective should be simple: reduce emissions while improving productivity, controlling operating costs and preparing the plant for future market and regulatory requirements.

What Is Green Steel?

Green steel generally refers to steel produced with significantly lower greenhouse-gas emissions than conventional steelmaking. However, there is no single technology that automatically makes steel “green.”

The carbon intensity of steel depends on the complete production pathway, including:

• Raw materials and feedstock
• Production technology
• Fuel consumption
• Electricity source
• Process efficiency
• Material yield
• Carbon-accounting methodology

Therefore, low-carbon steel and green steel should be viewed as outcomes of progressively reducing emissions rather than simply adopting one particular technology.

Why Green Steel Matters for Indian MSMEs

Steel MSMEs operate in a highly competitive environment where energy, raw materials, productivity and compliance directly affect profitability.

Decarbonisation can therefore become a business improvement strategy, not simply an environmental initiative.

Potential benefits include:

• Lower energy consumption
• Reduced process losses
• Improved equipment efficiency
• Better material utilization
• Lower operating costs
• Improved environmental performance
• Greater supply-chain competitiveness
• Better preparedness for carbon-related requirements
• Access to customers seeking lower-carbon products

For manufacturers supplying larger companies or export markets, the ability to measure and communicate product-level emissions may increasingly become commercially important.

Where Do Steel Plants Generate Emissions?

The first step toward steel plant decarbonisation is understanding where emissions originate.

Depending on the plant configuration, major sources can include:

• Coal, coke and other fuels
• Electricity consumption
• DRI production
• Furnaces and reheating
• EAF operations
• Captive power generation
• Rolling operations
• Material handling
• Process losses
• Upstream raw materials

A basic carbon assessment can categorize emissions into Scope 1, Scope 2 and Scope 3, helping management understand which sources should be prioritized.

Measure Before You Decarbonise

A steel manufacturer should not select technology before understanding its current performance.

A practical baseline can include:

1. Energy consumption per tonne of production
2. Electricity and fuel consumption
3. Production output
4. Specific energy consumption
5. Material yield
6. Process losses
7. Equipment efficiency
8. Major sources of emissions
9. Maintenance-related losses
10. Existing renewable-energy usage

An energy and process assessment can reveal improvement opportunities that require relatively modest investment.

You cannot effectively manage what you do not measure.

Start With Energy and Process Efficiency

For many MSMEs, the first decarbonisation opportunity may already exist inside the plant.

Potential measures include:

• Furnace optimization
• Combustion optimization
• Reducing heat losses
• Preventive maintenance
• Motor efficiency improvement
• Compressed-air optimization
• Power-factor improvement
• Reducing equipment idle time
• Better production scheduling
• Reducing rework and downtime
• Improving material yield
• Waste-heat recovery
• Digital energy monitoring
• Operator training

These measures can simultaneously reduce carbon emissions and production costs, making them an attractive starting point for smaller manufacturers.

Renewable Energy and Green Electricity

Renewable electricity can help reduce emissions associated with purchased power. MSMEs may evaluate options such as rooftop solar, captive renewable power or other renewable-energy procurement arrangements, depending on their technical and commercial circumstances.

However, renewable electricity alone does not automatically make steel green. It primarily addresses electricity-related emissions, while direct process emissions may require additional measures.

The right approach is therefore to combine energy efficiency, renewable electricity and process decarbonisation.

Technology Pathways for Lower-Carbon Steel

Different steel plants require different technology strategies.

Electric Arc Furnace (EAF)

EAF steelmaking uses electricity to melt metallic feedstock such as scrap. Its environmental performance depends significantly on electricity sources, feedstock and operating efficiency.

For suitable MSMEs, improving EAF efficiency and increasing access to lower-carbon electricity can contribute to emissions reduction.

Direct Reduced Iron (DRI)

DRI technology can use different reducing agents and fuels. Lower-carbon pathways can involve changes in fuel sources and, potentially, hydrogen-based reduction.

However, technology selection must consider raw-material availability, energy requirements, infrastructure and economics.

Hydrogen-Based Steelmaking

Hydrogen-based DRI is an important potential pathway for deep decarbonisation. However, it requires suitable hydrogen availability, renewable electricity, infrastructure and substantial investment.

For many MSMEs, hydrogen may therefore be a longer-term technology option rather than the first decarbonisation step.

Role of a Steel Consultancy Firm in Decarbonisation

A steel consultancy firm can help MSMEs convert the broad objective of “going green” into a practical, plant-specific investment and implementation roadmap.

The role can begin with an assessment of the existing plant and extend through project planning and implementation.

A steel consultancy can support:

1. Plant and Process Assessment

Consultants can review production processes, energy consumption, equipment performance, material utilization and operational losses to identify improvement opportunities.

2. Energy and Carbon Baseline

A structured assessment can help establish energy intensity, major emission sources and a practical carbon baseline.

3. Technology Evaluation

Rather than recommending a technology simply because it is considered “green,” consultants can compare alternatives such as energy-efficiency measures, renewable electricity, EAF improvements, waste-heat recovery and other technologies against the plant’s actual requirements.

4. Feasibility and Techno-Economic Analysis

Before major capital expenditure, a consultancy can evaluate:

• Capital cost
• Operating cost
• Energy savings
• Production benefits
• Carbon reduction
• Payback
• ROI
• Technology maturity
• Implementation constraints

This helps management prioritize projects based on both environmental impact and business value.

5. Decarbonisation Roadmap

A consultant can develop a phased roadmap covering immediate efficiency measures, medium-term modernization and longer-term technology transition.

6. Project and Engineering Support

Support can also extend to project planning, engineering advisory, implementation coordination, EHS considerations and workforce training.

For BCA Advisers, this aligns naturally with its broader capabilities in Steel & Metals Consultancy, Engineering & Manufacturing Consultancy, Process Improvement, Resource Optimization, Project Management, Feasibility Studies, EHS & Regulatory Compliance and Industrial Training.

A Practical Green Steel Roadmap for MSMEs

Phase	Key Actions
1. Measure	Energy audit, production baseline, carbon assessment
2. Optimize	Process improvement, maintenance, resource and energy optimization
3. Improve Energy Sources	Efficient electrical systems and renewable electricity where feasible
4. Modernize	Evaluate EAF, DRI, waste-heat recovery and other suitable technologies
5. Verify	Monitor energy intensity, carbon intensity, costs and operational KPIs

This phased approach allows MSMEs to begin with practical improvements before committing to major capital-intensive technologies.

How Should MSMEs Evaluate Green Steel Investments?

A decarbonisation project should not be selected solely because it promises carbon reduction.

Management should consider:

• Capital expenditure
• Operating expenditure
• Energy savings
• Production improvement
• Maintenance savings
• Carbon reduction
• Payback period
• ROI
• Financing availability
• Technology maturity
• Market requirements
• Future regulatory considerations

A techno-economic analysis can help determine which projects should be implemented immediately, which should be planned for the medium term and which technologies require further evaluation.

Green Steel and India’s Export Competitiveness

For Indian steel manufacturers, carbon intensity can increasingly influence international competitiveness.

Export-oriented companies may need stronger capabilities in:

• Carbon accounting
• Product-level emissions data
• Supply-chain transparency
• Environmental performance
• Customer sustainability requirements

Carbon-related mechanisms such as the EU’s Carbon Border Adjustment Mechanism (CBAM) make it increasingly important for exporters to understand their emissions data and future market requirements.

Green Steel in Eastern India

The green steel transition is particularly relevant to the industrial ecosystem of West Bengal, Odisha, Jharkhand, Chhattisgarh and Bihar, where steel, mining, engineering and manufacturing activities create opportunities for modernization and resource optimization.

For MSMEs in these regions, decarbonisation can be linked with broader objectives such as:

• Improving plant efficiency
• Reducing energy consumption
• Optimizing resources
• Modernizing equipment
• Improving competitiveness
• Preparing for changing customer requirements

The exact roadmap, however, should always be based on the individual plant’s technology, production capacity, energy mix, raw materials and financial capacity.

Common Mistakes MSMEs Should Avoid

Steel manufacturers should avoid:

• Buying technology before establishing a baseline
• Focusing only on carbon reduction
• Ignoring energy efficiency
• Selecting technology without techno-economic analysis
• Ignoring maintenance
• Failing to train operators
• Not establishing measurable KPIs
• Assuming renewable electricity solves every emissions problem
• Making unsupported “green steel” claims
