Biomass in Long-Term ESG Strategy for Manufacturing Plants

Biomass in ESG strategy should not be understood simply as replacing coal, fuel oil, or LPG with a “cleaner” fuel. In a 3–5 year ESG roadmap, many companies often start with familiar topics such as solar power, electricity savings, wastewater management, or emissions reporting. However, for industries that use large amounts of steam and heat, such as food processing, textiles, paper, rubber, animal feed, wood processing, and chemicals, the boiler system is often one of the key emission sources.

Why thermal energy matters in a factory ESG roadmap

In many manufacturing plants, thermal energy is harder to replace than electricity. Electricity can be optimized through energy management systems, rooftop solar, or renewable electricity procurement. But saturated steam and industrial heat are directly linked to the production process.

Boilers operate every day to support drying, steaming, heating, material processing, equipment cleaning, and continuous production. If this system uses coal, fuel oil, LPG, or other fossil fuels, the emissions are directly connected to the company’s Scope 1 emissions.

For C-level leaders, this creates three major pressures.

First, cost pressure. Fossil fuel prices can fluctuate significantly and directly affect production costs.

Second, emissions pressure. When international customers request ESG data, factories cannot only report small electricity-saving activities while ignoring a major emission source from the thermal energy system.

Third, transition pressure. Some manufacturing sectors are increasingly required to prove a clear decarbonization roadmap in order to maintain orders, join green supply chains, or meet requirements from parent companies.

In this context, ESG energy transition is not only about “changing fuel.” It is a decision related to operations, finance, engineering, data, and long-term business positioning.

>>> If your factory is reviewing its steam and thermal energy system as part of an ESG roadmap, NAAN Group can support the initial assessment and propose a suitable transition direction.

Biomass in ESG strategy: more than a fuel replacement

When people talk about biomass, they often think of rice husk, sawdust, wood chips, cashew shells, wood pellets, or agricultural and forestry residues. This understanding is correct, but not complete.

In ESG strategy, biomass should be viewed through three layers of value.

Environmental value: reducing emissions at source

Compared with continuing to operate fossil fuel boilers, switching to biomass boilers or purchasing biomass steam can help factories reduce emissions from steam and heat generation. This can be linked to Scope 1 emission reduction, depending on the ownership model, operation model, and the company’s emission accounting method.

The key point is that emission reduction happens at source. The factory changes how it generates energy for production instead of only compensating for emissions after they have already occurred.

For companies facing pressure from international customers, this difference is important. An ESG report becomes more credible when the company can show that actual operations have changed, supported by measurable data.

Social value: creating local value chains

Biomass does not exist separately from local economies. Fuel sources often come from agricultural residues, forestry residues, or biomass waste from processing activities.

If collected, sorted, processed, and managed properly, biomass can create additional value for local communities. Farmers, collection units, pre-processing facilities, and fuel suppliers can participate in a new supply chain.

This is one reason why sustainable biomass energy is different from some other energy options. It does not only support emission reduction inside the factory but also has the potential to extend value across the local supply chain.

However, companies need to be careful. A biomass supply chain only creates real ESG value when it is managed transparently, stably, and responsibly in terms of origin, quality, labor safety, and environmental impact.

Governance value: building data for reporting and decision-making

ESG cannot stop at intention. A strong ESG strategy needs data.

For thermal energy systems, relevant data may include steam consumption, fuel consumption, emission factors, boiler efficiency, operating hours, fuel consumption per ton of steam, energy costs, and estimated emission reduction.

When these data points are recorded consistently, factories have a stronger basis for ESG energy reporting, internal emissions reporting, customer reporting, or supplier assessment programs.

This is why biomass in ESG strategy must go together with operational capability and measurement, not just fuel purchasing.

Carbon offsets or real emission reduction through biomass?

When building a net zero roadmap, many companies consider purchasing carbon offsets. Offsets can be part of a climate strategy, but they should not fully replace actual emission reduction efforts.

Carbon offsetting is essentially compensation. The company still emits in its current operations, then purchases credits from another project to balance part of those emissions.

By contrast, emission reduction through biomass changes the steam and heat generation system directly. The factory addresses an emission source within its own production process.

For C-level leaders, the difference lies in control.

With offsets, companies depend on the quality, transparency, and credibility of external projects. If a project is not properly verified, communication and reputation risks may arise.

When switching the thermal energy system to biomass, companies can better control operational factors such as fuel, steam output, cost, emissions, and measurement data.

This does not mean biomass will always replace offsets completely. In many net zero pathways, companies may still need offsets for hard-to-abate emissions. However, from a strategic perspective, reducing emissions at source should usually come first.

In other words, offsets can be a supporting tool. Thermal energy transition is a real operational change.

>>> If your company needs a practical step before considering offsets, low-carbon biomass steam can be a realistic option in a 3–5 year ESG roadmap.

From emission reduction to circular production

Biomass is unique because it connects two goals: emission reduction and circular economy.

At the input stage, biomass can come from agricultural and forestry residues such as rice husk, sawdust, wood chips, cashew shells, or by-products from processing activities. Instead of being wasted or handled inefficiently, these biomass streams can be converted into fuel for boilers.

At the output stage, biomass combustion produces steam and heat for production. This is the clearest and most measurable application for factories today.

In the longer term, biomass ash or biochar may create opportunities for further research and application. For example, some development directions may include soil improvement materials, absorbent materials, or inputs for other circular models.

However, it must be clearly stated that not all biomass ash or biochar can be used directly as fertilizer. Reuse requires testing for composition, heavy metals, safety, technical standards, and relevant legal requirements.

Therefore, for factories, the more suitable perspective is this: biomass currently plays a practical role in converting residues into low-carbon thermal energy. The next circular loops are potential development opportunities that require further research and verification.

This is a cautious but valuable approach. Companies do not need to overclaim, but they can still build a circular production roadmap based on data and gradual expansion.

How to integrate biomass thermal energy into ESG reporting

One of the challenges of ESG in manufacturing is turning operational activities into reportable information. If a company only says “we have switched to biomass,” that statement is not strong enough.

To include biomass in ESG reporting, factories need several layers of data.

Input data

The company should record the type of biomass fuel used, supply source, consumption volume, moisture level, fuel quality, and supply chain stability.

Where possible, biomass sources should be categorized by local area, type of residue, and supplier. This helps the report include additional information on green supply chains and local value creation.

Operational data

Factories need to monitor steam output, steam pressure, operating hours, boiler efficiency, fuel consumption per ton of steam, and downtime rate.

These data are not only useful for ESG. They also help the operations team optimize energy costs and control technical risks.

Emissions data

The most important layer is emissions data. Companies need a clear, consistent calculation method that is aligned with the reporting framework they apply.

For factories facing international customer requirements, this data can be used in supplier assessments, sustainability reports, or Scope 1/2 emission reduction roadmaps.

ESG communication data

Once data are available, companies can communicate more convincingly. Instead of using general claims, the factory can clearly explain which part of the thermal energy system has been converted, which emissions category has been reduced, which indicators are being tracked, and what the next step is.

This is the foundation for making ESG part of operational governance, not only a communication activity.

>>> ESG needs real data and consistent measurement. NAAN Group can support factories in building an emissions data foundation from biomass steam systems for reporting and internal governance.

Key questions before adding biomass to a long-term ESG strategy

Biomass has strong potential, but not every factory should adopt it in the same way. Before integrating biomass into the factory ESG roadmap, C-level leaders should answer several important questions.

1. How much does the current system emit?

A company needs to understand its current baseline before setting targets. What fuel does the boiler currently use? How much fuel is consumed each month? What is the current steam or heat cost? How much does this system contribute to total emissions?

Without a baseline, it is difficult to prove the impact after transition.

2. Is steam demand stable?

Biomass can fit many production models, but steam load needs to be analyzed carefully. Does the factory operate continuously or by shift? Does steam demand fluctuate significantly? Are there seasonal peaks?

These factors affect boiler capacity, operating strategy, backup planning, and cost.

3. Is the local biomass supply stable enough?

Sustainable biomass energy depends heavily on the fuel supply chain. Factories need to assess local supply capacity, seasonal stability, logistics costs, and fuel quality.

Even a well-designed biomass boiler system can face risks if the fuel supply is unstable.

4. Should the company invest directly or purchase steam?

Not every factory wants to spend large CAPEX on a full boiler system. Some companies may be better suited to a biomass steam purchase model, where the service provider takes responsibility for part or all of the operation, maintenance, and fuel supply.

This model helps factories access low-carbon steam without handling the entire technical challenge from the beginning.

5. How will ESG data be recorded?

If the transition is only made to create an ESG story, its long-term value will be limited. From the beginning, companies should define the indicators to track, how data will be recorded, and how that data will be used in reporting.

This is where boiler operation connects with ESG governance.

Where does NAAN Group fit into this strategy?

NAAN Group focuses on low-carbon thermal energy solutions for manufacturing plants, especially through the Low-carbon Steam-as-a-Service / Biomass Steam Service model.

Instead of approaching the market only as an equipment seller, NAAN can support companies across several key areas: boiler transition consulting, low-carbon saturated steam supply, boiler operation and maintenance, stable biomass fuel supply, and emissions data support for ESG/MRV purposes.

For factories currently using coal, fuel oil, LPG, electricity, or outdated boiler systems, the biomass steam purchase model can help reduce initial investment pressure. Companies do not have to manage the entire process of design, operation, fuel sourcing, and efficiency optimization by themselves.

The important point is that NAAN should not be seen as only a fuel supplier. Its more relevant value lies in helping factories turn their thermal energy system into a measurable part of ESG strategy.

For industries such as food processing, textiles, paper, rubber, animal feed, wood processing, and chemicals, this can be a practical step to reduce emissions at source, improve reporting data, and prepare for requirements from customers or supply chains.

FAQ: Common questions about biomass and ESG

Is biomass considered industrial renewable energy?

Biomass is often classified as renewable energy when the fuel comes from renewable biological sources such as agricultural or forestry residues. However, its sustainability depends on fuel origin, collection method, transportation, quality control, and emissions calculation method.

Can biomass help reduce Scope 1 emissions?

It can, if biomass replaces fossil fuels in the steam or thermal energy system operated by the company. However, the specific reduction must be calculated based on fuel consumption data, steam output, emission factors, and the reporting method applied by the company.

How is purchasing biomass steam different from investing in a biomass boiler?

Direct investment allows the company to own the asset but requires CAPEX, an operation team, maintenance capacity, and fuel management. Purchasing biomass steam allows the company to access low-carbon steam through a service model, reducing initial investment pressure and transferring part of the operational responsibility to a specialized provider.

Conclusion

Biomass in ESG strategy is not only about changing boiler fuel. For manufacturing plants, it can be a practical direction to reduce emissions at source, optimize energy costs, generate ESG reporting data, and gradually move toward a circular economy model.

The key is to start from the current operating baseline, steam demand, local biomass supply, investment model, and the data set that needs to be tracked. When these elements are designed properly, biomass can become a meaningful pillar in a long-term ESG roadmap.
