At DS Smith, our circular approach means we always see waste as a potential resource. Which is why our Lucca paper mill in Italy is capturing heat previously lost during our paper manufacturing drying process to heat all the buildings on site – replacing fossil fuels and reducing carbon emissions.

In November 2020, Resolute Forest Products received the American Forest & Paper Association’s Leadership in Sustainability – Energy Efficiency/Greenhouse Gas Reduction award in recognition of the energy efficiency and greenhouse gas (GHG) reduction initiatives we undertook at our Coosa Pines pulp mill in Alabama.

Georgia Pacific’s Leaf River Cellulose plant in New Augusta, MS is the first paper pulp mill in the United States to receive EPA’s ENERGY STAR certification. Like ENERGY STAR products, ENERGY STAR certified plants are the most energy-efficient in their sectors.

Pohjolan Voima’s values – skillfully, boldly and together – came to life when the company succeeded in reducing NOx emissions and improving energy efficiency through combustion optimization and data analyses at its two biopower plants.

CASE STUDY - Four of Thermal Energy International's (TEI) engineers travelled to the Resolute FP Canada Inc. ("Resolute") pulp and paper mill in Thunder Bay, Ontario to conduct an onsite survey and specification process to properly size and replace the facility's existing mechanical traps with high-efficiency GEMTM Steam Traps.


To minimize drying energy costs this paper proposes optimizing dryer section hood and air system efficiency via the use of zero pressure line control combined with humidity control to maintain maximum exhaust humidity.

In 2015, operations managers and manufacturing engineers at the Green Bay Broadway (GBB) mill began getting a new monthly bill in their email box. It showed them just how much energy their equipment had used the previous month – and how much it cost.

A high-efficiency thermocompressor will offer an operating cost advantage if the source of the motive steam bypasses a cogeneration turbine or if the source of motive steam is produced on a high-pressure boiler separate from the source of low-pressure steam.

Energy optimization is priority today in all sectors of fabrication including tissue and towel. The Yankee drying system on the tissue machine represents an interesting savings opportunity since both natural gas and steam are utilized therefore significantly impacting energy costs.

In the last article we looked at optimization strategies for the energy consumption on a Yankee Dryer system, particularily the natural gas consumption in the Yankee Hood versus the steam in the Yankee cylinder.

Yankee air systems are energy intensive and should routinely be checked to ensure that they run at an optimal level. A proper hood balance ensures maximum thermal efficiency (i.e. BTU (fuel) per ton of paper).
