joj skoda ze si ma nepocuval ;)

"PCO2 are potential carbon dioxide emissions of a wood product due to oxidation, cf is the carbon content in the dry biomass (a standard value of 0.5 was used), ω the remaining moisture in the product (8–12 percent for sengon wood51), ρω the raw density of wood (350 kg/m3 ± 10% for sengon wood51), Vω product volumes at moisture ω, adapted to the functional unit of 1 m3. Published values for moisture and raw density of sengon wood vary considerably (Table 1). The corresponding values for PCO2 calculated using Eq. (1) range from 421.94 to 916.81 kg CO2/m3 with an arithmetic mean of 669.38 kg CO2/m3. For plywood, the three sengon plywood mills use on average 10.13 percent resin per m3 plywood. This results in a carbon dioxide uptake of 602 kg CO2 per m3 sengon plywood."

"As a result, post-consumer scrap has a carbon footprint of about 0.5 tons CO2 per ton aluminium. This results from scrap collection, transport, sorting and remelting."

dufam ze je ta preglejka aspon bez formaldehydu https://www.maxiply.com.au/blog/formaldehyde-in-plywood-what-does-it-mean-to-you/ :P


v dobrom a gratulky ;)
