Hupenyu hwepamba hune hutano, hunopisa uye hwakanaka ndizvo zvinotsvakwa nevanhu uye zvinoshuviwa nazvo. Kuchengetedzeka uye kushanda kwezvakatipoteredza kwezvinhu zvakaita sefenicha, pasi, makabati nemakabati mumba zvine simba guru pahupenyu hwepamba. Kunyanya kusarudzwa nekushandiswa kwezvinonamira, pendi nemadhayi. Kunyangwe huwandu hwakawanda hwe formaldehyde muglue huchibatsira kuvandudza kushanda kwebhodhi, pamwe nezvinodiwa nemusika zvehutano nekuchengetedzwa kwezvakatipoteredza uye kuvandudzwa kuri kuitwa kwemidziyo, tekinoroji uye maitiro. Mwero wekubuda kwe formaldehyde mumapanera akavakirwa pamatanda wakaramba uchivandudzwa, kubva pakuona E2 (formaldehyde content ≤ 30mg/100g) nenzira yekuburitsa maburi yakabviswa muChina, kusvika pakuona E1 (≤ 0.124mg/m3) uye E0 (≤0.05mg/m3) uye ENF (≤0.025mg/m3, kureva kuti hapana aldehyde) muChina. Boka redu ndiro rakatanga China National Innovation Alliance yeNo-Added formaldehyde Wood-based Panels. Fiberboard, particleboard uye plywood series yeboka redu inonyanya kusimudzira nekutengesa zvigadzirwa zvisina aldehyde. Chigadzirwa ichi chawana China Environmental Labeling Certification 、China Green Product Certification uye Hong Kong ECO mark License ，Pakati pazvo, particleboard yedu neplywood zvakawana NAF (No-Added formaldehyde) certification yakapihwa neCalifornia Air Resources Board (CARB). Ichi ndicho chitupa cheNAF chakanyanya kuoma pasi rose, Mapaneru eENF akagadzirwa nematanda akagadzirwa neboka redu anoshandisa No-Added formaldehyde glue senge bean glue kana MDI uye anogadzirisa maitiro ekugadzira epamberi kuti ave nechokwadi chekuti formaldehyde inobuda mumapaneru inosangana neENF standard uye kuve nechokwadi chekuti chigadzirwa chinoshanda zvakanaka uye chakasimba. Nerutsigiro rwetekinoroji yepamusoro yeveneer uye edge banding yemabhodhi ekutevera. Kuchengetedzeka nehutano hwefenicha yeNo-Added formaldehyde yeChina iri padanho repamusoro pasi rose.
