Pulp and Paper
Reliable, efficient, and low-carbon energy for continuous pulp and paper production.
About the Pulp and Paper Industry
The pulp and paper industry is one of the most energy-intensive manufacturing sectors, supplying essential materials for packaging, printing, and hygiene products. Production relies on both electrical and thermal energy for pulping, bleaching, drying, and finishing — all of which must be maintained with high precision and consistency.
Energy typically accounts for a large share of operating costs, with any disruption risking material loss, quality variation, or equipment downtime. In a competitive global market, mills are increasingly focusing on improving energy efficiency, reducing carbon emissions, and enhancing energy security.
Combined heat and power (CHP) offers an effective solution by producing both electricity and process heat on-site, using a single fuel input. This approach maximises efficiency, reduces fuel consumption, and provides dependable power and steam for continuous operation. When combined with microgrid control systems, CHP allows flexible, resilient energy management that supports sustainability goals and long-term cost stability across pulp and paper manufacturing operations.
Energy Resilience in Pulp and Paper Manufacturing
Energy reliability is essential for the stability of mechanical and thermal processes in pulp and paper production. Gas engine-based CHP plants provide dependable onsite power and heat, safeguarding against grid instability or external outages.
When integrated with advanced control systems, these plants can seamlessly switch between grid-connected and island operation, optimising generation in real time to match process requirements. This ensures continuous operation of pulping, drying, and finishing equipment while maintaining consistent product quality. The result is enhanced efficiency, lower emissions, and stronger energy resilience for high-demand industrial environments.

Microgrids and Hybrid Energy Systems
Combined Heat and Power (CHP)
CHP systems simultaneously generate electricity and recover waste heat from engine exhaust and cooling circuits to provide steam or hot water for pulping, drying, or bleaching. With overall efficiencies exceeding 80%, CHP systems significantly reduce fuel use, emissions, and energy costs. By producing power and thermal energy onsite, mills minimise dependence on grid supply, improve process reliability, and stabilise long-term energy budgets. CHP also supports carbon reduction targets by enabling the use of renewable and low-carbon fuels within continuous manufacturing operations.
Microgrids and Hybrid Energy Systems
Microgrids integrate CHP plants with renewable generation and battery energy storage to optimise energy performance. For pulp and paper mills, these systems enhance operational flexibility by balancing electricity, steam, and heat loads across multiple processes. During grid disturbances, microgrids maintain power continuity and can operate autonomously to protect production. This approach improves cost efficiency, enables renewable integration, and strengthens overall sustainability performance. By combining local generation with intelligent control, microgrids support both resilience and long-term decarbonisation goals for industrial energy networks.

Frequently Asked Questions about Pulp and Paper Industry Energy Systems
Technical and Engineering
How does CHP improve efficiency in pulp and paper manufacturing?
CHP systems recover and reuse waste heat from power generation for thermal processes, improving efficiency and reducing fuel use.
Can pulp and paper facilities use renewable fuels in CHP systems?
Yes. Clarke Energy’s gas engines can operate on renewable fuels such as biogas or biomethane, supporting net-zero objectives.
What role do microgrids play in pulp and paper operations?
Microgrids optimise onsite generation, maintain energy stability during grid interruptions, and integrate renewables effectively.
Can CHP systems provide steam for paper drying?
Yes. Recovered heat from CHP engines can generate steam or hot water used in pulping, drying, and finishing stages.
Financial and Commercial
What cost savings can be achieved with CHP?
Efficiencies above 80% typically deliver major reductions in energy spend compared to purchasing grid power and producing heat separately.
Are funding options available for energy efficiency projects?
Yes. Many regions offer grants or financing incentives for CHP and low-carbon industrial technologies.
What is the payback period for CHP systems?
Typical payback periods range from five to eight years, depending on plant size, heat recovery, and energy tariffs.
Can onsite generation stabilise long-term costs?
Yes. Generating energy onsite reduces exposure to grid price volatility and provides predictable operational costs.
