Njira zopangira anti dzimbirimapaipi amafuta

(1) dzimbiri la chitoliro→kupaka utoto wa asbestos ufa wosakaniza ndi dongo la waya wamingaminga wokutidwa ndi zida zotchinjiriza→kupukuta simenti ya asbestosi yoteteza chipolopolo cha dzimbiri burashi.

(2) Dzimbiri laburashi la payipi→kuvala perlite matailosi kanasonkhezereka waya→gawo la chitetezo cha asphalt chinyezi chotchinga→outsourcing kanasonkhezereka chitsulo burashi mapeto.

(3) chitoliro dzimbiri→mmwamba burashi phukusi superfine ubweya chipolopolo (kapena thanthwe ubweya, polyurethane thovu ozizira matailosi)→(zojambula za aluminiyamu kapena asphalt shingle) wosanjikiza chitetezo cha chinyezi→kumaliza kwachitsulo.

(4) Dzimbiri laburashi la payipi→jekeseni mwachindunji polyurethane thovu zotayidwa zitsulo zotayidwa mu payipi→malaya zoteteza wosanjikiza kanasonkhezereka chitsulo.
