Kev lag luam pulp thiab ntawv yog tsim los ntawm kev tsim cov ntawv ntawm ntau yam zoo, ntau daim duab los qhia nrog ntau yam khoom, nrog raucov khoom los ntawm cov ntaub ntawv no. Fiberboard (nrov npe hu ua fiberboard) thiab insulating fiber ntau raw cov ntaub ntawv kuj yog cov khoom tseem ceeb ntawm no sector ntawm lub teb chaws kev khwv nyiaj txiag. Zoo li txhua yam kev tsim khoom, kev lag luam pulp thiab ntawv hauv Russia thiab thoob ntiaj teb muaj kev phiv los ntawm nws txoj haujlwm. Yog li, lawv yog fodder poov xab, qee cov tshuaj lom neeg los ntawm cov chav kawm ntawm ethylene thiab fatty acids, turpentine, rosin, thiab lwm yam.

Tib lub sijhawm, hauv ntau lub xeev, hav zoov saturates nrog nws cov ntaub ntawv pib xws li kev lag luam xws li kev lag luam pulp thiab ntawv (kwv yees li 70%), thiab lwm yam. Finland yog ib lub tebchaws no. Nyob rau tib lub sijhawm, hauv lub xeev no, thiab lwm yam, ib yam nkaus, kev rov ua dua ntawm cov ntaub ntawv raw - recyclables lossis khib nyiab.

Cov thev naus laus zis tshiab tshaj plaws uas siv nyob rau theem tam sim no ua rau nws tuaj yeem ua ke nrog cov duab los qhia thiab ntawv nrog lwm cov ntaub ntawv. Qhov tshwm sim ntawm kev sim ua tiav ntawm qhov xwm txheej no yog qhov nthuav dav ntawm cov khoom ntim dej tsis zoo, ruaj khov thiab lub teeb yuag uas siv rau hauv kev thauj mus los, khaws cia thiab muag ntawm qee hom kua dej.

Raws li txoj cai, kev lag luam pulp thiab ntawv siv spruce thiab qee cov ntoo tawv rau nws lub hom phiaj. Cellulose yog tau los ntawm kev ua tshuaj ntawm ntoo thuv thiab birch.

Thaum lub sij hawm siv cov khoom no, cov khoom sib xyaw ua ke raug tsim uas cuam tshuam rau ib puag ncig. Cov neeg tiv thaiv ntawm lub ntiaj teb, hauv kev koom tes nrog ntau lub tuam txhab tshuaj, tawm tswv yim txog kev siv cov pa oxygen rau cov hom phiaj no, uas tsis muaj kev cuam tshuam rau kev ua qias tuaj hauv dej thiab huab cua. Tam sim no, ntau lub tuam txhab tau sim hloov mus rau ib puag ncig tus phooj ywg thev naus laus zis.
