Background Replacing non-renewable materials and energy with wood offers a potential strategy to mitigate climate change if the net emissions of ecosystem and technosystem are reduced in a considered time period. Displacement factors (DFs) describe an emission reduction for a wood-based product or fuel which is used in place of a non-wood alternative. The aims of this review were to map and assess DFs from scientific literature and to provide findings on how to harmonise practices behind them and to support coherent application. Results Most of the reviewed DFs were positive, implying decreasing fossil GHG emissions in the technosystem. The vast majority of the reviewed DFs describe avoided fossil emissions either both in processing and use of wood or only in the latter when wood processing emissions were considered separately. Some of the reviewed DFs included emissions avoided in post-use of harvested wood products (HWPs). Changes in forest and product carbon stocks were not included in DFs except in a few single cases. However, in most of the reviewed studies they were considered separately in a consistent way along with DFs. DFs for wood energy, construction and material substitution were widely available, whereas DFs for packaging products, chemicals and textiles were scarce. More than half of DFs were calculated by the authors of the reviewed articles while the rest of them were adopted from other articles. Conclusions Most of the reviewed DFs describe the avoided fossil GHG emissions. These DFs may provide insights on the wood-based products with a potential to replace emissions intensive alternatives but they do not reveal the actual climate change mitigation effects of wood use. The way DFs should be applied and interpreted depends on what has been included in them. If the aim of DFs is to describe the overall climate effects of wood use, DFs should include all the relevant GHG flows, including changes in forest and HWP carbon stock and post-use of HWPs, however, based on this literature review this is not a common practice. DFs including only fossil emissions should be applied together with a coherent assessment of changes in forest and HWP carbon stocks, as was the case in most of the reviewed studies. To increase robustness and transparency and to decrease misuse, we recommend that system boundaries and other assumptions behind DFs should be clearly documented.

“…Sawnwood used for packaging (pallets) (25 kg pallet −1 ) was assumed to replace high-density polyethylene (HDPE) pallets (5.5 kg pallet −1 ) based on EPAL (2021) and APLP (2021). Wooden furniture replacement built on a representative average of non-wooden furniture, consisting out of steel (67%), polypropylene (PP) (11%), polyurethane foam (PUR) (10%), glass (5%), aluminium (5%), and polyvinylchloride (PVC) (2%) based on Geng et al (2019). Paperboard packaging replacement of plastic packaging considered an average plastic packaging recycling rate of 67% and recycling from wood packaging to be 41% (SCB 2021).…”

Nordic forest management towards climate change mitigation: time dynamic temperature change impacts of wood product systems including substitution effects

et al. 2022

Climate change mitigation trade-offs between increasing harvests to exploit substitution effects versus accumulating forest carbon sequestration complicate recommendations for climate beneficial forest management. Here, a time dynamic assessment ascertains climate change mitigation potential from different rotation forest management alternatives across three Swedish regions integrating the forest decision support system Heureka RegWise with a wood product model using life cycle assessment data. The objective is to increase understanding on the climate effects of varying the forest management. Across all regions, prolonging rotations by 20% leads on average to the largest additional net climate benefit until 2050 in both, saved emissions and temperature cooling, while decreasing harvests by 20% leads to the cumulatively largest net climate benefits past 2050. In contrast, increasing harvests or decreasing the rotation period accordingly provokes temporally alternating net emissions, or slight net emission, respectively, regardless of a changing market displacement factor. However, future forest calamities might compromise potential additional temperature cooling from forests, while substitution effects, despite probable prospective decreases, require additional thorough and time explicit assessments, to provide more robust policy consultation.

“…There are methods proposed for burning fuel briquettes and waste in special furnaces without releasing formaldehyde into the environment, for example, in pyrolysis plants [7], [8]. However, this method of disposal requires strict control of emissions into the atmosphere, which is not always ensured during thermal process planning [9].…”

The article outlines the problem of accumulation of short-fibered waste generated during chipboard sawing. Intense impact on the material determines a high level of technological availability of wood waste. The research objective is to create magnesia composite materials for various purposes based on chipboard processing waste. Moulding sands containing caustic magnesite, fly ash, aluminosilicate ash microsphere, wood waste and magnesium chloride solution have been studied. Change in the ratio of moulding sands’ components provided production of finely dispersed composite material, and granules of cylindrical and spherical shapes. Composite materials of coarse-pored structure have been developed on the basis of magnesia granules and hybrid magnesia-ash binder. Combination of layers of finely dispersed and coarse-pored materials has been proposed to form composites of variotropic structure with density 780–840 kg/m3 and strength 9.7–11.9 MPa. Combined structures’ stability is achieved due to the high adhesive ability of magnesia binders and genetic commonality of various layers.
