Lintlha tsohle tse ka har'a karolo e latelang ea "Emissions" li bokelloa ho tsoa ho EWPAA: Tekanyetso ea Tekheniki, Mosi oa Formaldehyde ho tsoa Plywood le Laminated Veneer Lumber.
Karolo ena e bua ka tlhahlobo e tsoelang pele ea indasteri ea tlhahiso ea formaldehyde ho tsoa lihlahisoa tse tsebahalang tsa EWPAA, ho akaretsa lipatlisiso tse phethetsoeng ke EWPAA tsa hore mesi e tsoang lihlahisoa tsa Mofuta oa A, e nang le likhomaretsi tsa phenolic, e emela ho feta 90% ea tlhahiso ea EWPAA e nang le lefela.
Formaldehyde
Formaldehyde ke khase e se nang 'mala, e monko o matla e hlahang ka tlhaho ka har'a tikoloho 'me e ntšoa ke mekhoa e kang ho bola, ho cha le ka tlhaho ke mefuta eohle ea lifate.
Metsi ea Formaldehyde
Plywood e entsoe ka mefuta e 'meli ea sekhomaretsi ea mantlha: Phenol Formaldehyde (PF) le polasetiki ea amino, e kenyelletsang Melamine Urea Formaldehyde (MUF) le Urea Formaldehyde (UF).
Ho na le phapang e kholo k'hemistri lipakeng tsa mefuta e 'meli ea likhomaretsi. Ka lihlahisoa tse tlanngoeng ke PF, ka mor'a hore formaldehyde efe kapa efe e tlase e tsoang ts'ebetsong ea tlhahiso e felile ka mor'a matsatsi a seng makae, ha e ntše formaldehyde.
Sekhomaretsi sa PF, se khetholloang ka 'mala oa sona o motšo, se bitsoa Mofuta oa A tlas'a litekanyetso tsa ply tsa Australia le New Zealand joalo ka ha o sebelisoa ha ho etsoa plywood ea sebopeho, lihlahisoa tsa kantle tsa marine plywood (Mofuta oa A).
