Over 11 million cubic meters of timber were harvested from the coastal forests of British Columbia in 2017. For transport, the logs are usually floated in the water and towed along the coastal waters along Fraser River to sawmills. The submerged timber's chlorine content is up to 100 times higher than the timber harvested from inland. The sawmill residues leftover from cutting the salt-laden timber are unsuitable to be burned in boilers. In this study, ground sawdust, bark, and wood chips of three species: Douglas fir, hemlock, and western red cedar from the Lower Mainland, as well as spruce-pine-fir (SPF) from Vancouver Island, were washed for 5 min using tap water under constant stirring and pressed on a flat metal bed for 30 s using a mechanical hydraulic press. The chlorine content dropped from 2,000–24,000 ppm to below 700 ppm db (dry basis). The low salt biomass meets the ISO 17225-2 quality standard for wood pellets. The chlorine removal efficiency of this treatment method was 88–95%. The reduction in ash content of the washed and pressed samples ranged was 45–85% of the ash in the untreated biomass.

2017 年，从不列颠哥伦比亚省的沿海森林中收获了超过 1100 万立方米的木材。为了运输，原木通常漂浮在水中，并沿着弗雷泽河沿岸的沿海水域拖到锯木厂。沉水木材的氯含量比从内陆采伐的木材高出 100 倍。切割含盐木材的锯木厂残余物不适合在锅炉中燃烧。在这项研究中，三种树种的磨碎锯末、树皮和木片：来自低陆平原的道格拉斯冷杉、铁杉和西部红柏，以及来自温哥华岛的云杉松冷杉 (SPF)，被洗涤 5 分钟在不断搅拌下使用自来水，并使用机械液压机在平坦的金属床上压制 30 秒。氯含量从 2,000-24 下降，000 ppm 至低于 700 ppm db（干基）。低盐生物质符合 ISO 17225-2 木屑颗粒质量标准。这种处理方法的除氯效率为 88-95%。洗涤和压制样品的灰分含量减少了未处理生物质中灰分的 45-85%。
