about 1/3rd correct. It is not made with epoxy[1]. Bamboo lumber is made with urea formaldehyde just like plywood. UF is made from CO2, ammonia, and methanol[2]. Methanol can come from plants or from fossil fuels. Ammonia uses 55% of global hydrogen, and that hydrogen comes from fossil fuels. Typically natural gas. There are also No-Added-Formaldehyde brands that used soy/PVA/other adhesives which can rely less or more fossil fuels (PVA is wood glue- vinyl based).
Engineering bamboo (flooring doesn't always use UF) has ~5% wt. UF, so 20 kg of lumber requires ~.4 kg of ammonia. Using a methane feedstock that translates to ~.85 kg of CO2. 4% of the CO2 captured by the bamboo, for context. Ammonia can also be made from water, via electrolysis- .64 kg per 20 kg of bamboo.
[1]: UF does not contain an epoxide group. Note also that epoxide is an incredibly generic type of chemical- all it means is that two pairs of radicals and an oxygen form a triangular bond. Epoxides can take all kinds of forms and be made from all kinds of stuff. For instance Epichlorohydrin is used to make some of the most common epoxy resins and is produced from glycerol, which comes from plant/animal sources generally. Not all of it, but most of it.
