“…The cost and environmental impact of storage and incineration of wood waste such as wood impregnated with Cu-based preservative or fiber based panel board (MDF, HDF) are very high, and recycling or upcycling of these waste has great potential on global warming and carbon sequestration in wood industry [ 41 , 42 ]. Considerable efforts of research have been carried out to explore the bioremediation potential of wood decay bacteria and fungi in the contaminant’s removal from wood or water effluents [ 43 , 44 , 45 , 46 , 47 ]. Several studies have shown that fungi and bacteria are tolerant to different constituents of preservatives such as copper [ 48 ], CCA, and creosote [ 49 , 50 ].…”

“…The lactic acid bacteria Lactobacillus bulgaricus and Streptococcus thermophilus have been used to extract up to 93% copper, 86.5% chromium, and 97.8% of the arsenic after 8 days of fermentation at laboratory scale [ 51 ]. Fungi belonging to Basidiomycota have particularly interesting wood decontamination capacities [ 43 ]. Because of their ability to degrade the aromatic nuclei of lignin, the fungi that cause white rot are also able to assimilate the cyclic molecules contained in preservatives such as creosotes [ 45 ].…”

Cascading Recycling of Wood Waste: A Review

et al. 2021

Wood is an increasingly demanded renewable resource and an important raw material for construction and materials. In addition, new consumption habits are leading to the production of ever greater volumes of waste wood, which constitutes a feedstock that can be mobilized for the cascade production of new materials such as particleboard. However, current legislation and wood waste recycling processes need to be improved in order to maximize the volumes that can be reused and to upgrade the properties of the recycled wood. This review describes wood waste flows and volumes available in Europe, the current French and European legislation, and the innovations under development in this field: innovative automated sorting techniques, physical-chemical processes for cleaning residual glue from the surface of wood particles, cleaning of MDF, and bioremediation processes for cleaning hazardous wood contaminated by heavy metals or creosote.

“…Previous studies have already reported that biochar is highly recalcitrant and able to improve some soil properties by influencing biochemical and biological processes [ 2 , 3 , 4 , 5 ]. Biochar amendment significantly enhances the nutrient availability and nutrient retention of a wide range of soils [ 6 ], in addition to the positive contribution to the improvement of other physical and biological soil properties [ 7 , 8 , 9 , 10 ] and to metal retention [ 11 ]. However, the capacity of this material to provide or enhance soil fertility extremely depends on the type of feedstock and pyrolysis conditions [ 12 ].…”

The effects of biochar on soil–plant–microorganisms systems are currently being extensively investigated. Considering that arbuscular mycorrhizal fungi (AMF) play an essential role in nutrient dynamics, the present study aims at understanding vine shoot-derived biochar effects on AMF activity and the impact of their multiplication in soils on water-stress resistance of plants. Three agronomic tests were performed in greenhouse pots. The first experiment evaluated the effects of three factors: final pyrolysis temperature for biochar production (400 °C and 600 °C), application rate (0 weight-wt.- % as a control, 1.5 wt. %, and 3.0 wt. %) and texture of the growing media (sandy-loam and clay-loam origin) on AMF, microbial communities and phosphatase activity. In the second experiment, an indigenous consortium of AMF was multiplied through the solid substrate method and sorghum as a trap plant with biochar addition. This process was compared to a control treatment without biochar. Obtained inocula were tested in a third experiment with lettuce plants under different water irrigation conditions. Results from the first experiment showed a general increase in AMF activity with the addition of the biochar produced at 400 °C in the sandy-loam texture substrate. Results of the second experiment showed that the biochar addition increased AMF root colonization, the number of AMF spores and AMF infective potential. Results of the third experiment showed that biochar-derived AMF inoculum increased AMF root colonization, AMF spores, dry biomass and the SPAD index in a lettuce crop under low-water irrigation conditions.

“…These substances present an excellent performance in terms of wood preservation, where Chromium acts as a xative, and Copper and Arsenic as a fungicide and insecticide, however, because they have metals in their composition, they can be highly toxic to human health and the environment [2; 3]. Thus, the volume of material installed throughout the world, even after the reduction of its application due to the legislation of the countries of Europe and USA, still worries, because the material used, in the most varied sectors, has a useful life of up to 50 years [4].…”

“…On the other hand, since wood is a renewable natural resource, it should be widely used in the most varied segments and not simply replaced by elements such as concrete and steel, for instance. Thus, investigations aiming at solutions for the nal destination or reuse of correctly treated wood waste are of fundamental importance for the sector and should be encouraged [4]. Some procedures that extract the metals present in the material preserved with CCA have already been studied for some time [6; 7], but results are still scarce and should be better elucidated.…”

Waste from treated wood can be hazardous to the environment and human health. Therefore, research is needed to investigate what to do with this waste. The electro-removal technique is a viable technique to remove the copper, chromium and arsenic metals contained in the CCA-treated wood. But is the CCA really removed? the present study investigated this cause, using the living organism Trametes versicolor to verify this hypothesis.
