A:Chifukwa cha kukwera mtengo kwake komanso magwiridwe antchito apamwamba, imakhazikika m'mafakitale owonjezera amtengo wapatali omwe ali ndi zofunikira zotchinga kwambiri:
- Makampani a Pharmaceutical:Makamaka PTP matuza phukusi la mankhwala kunja, zomwe zimafuna chinyezi chambiri komanso kukana oxygen.
- New Energy Industry:Filimu ya aluminium-pulasitiki (Soft Pack) kwa mabatire amphamvu kapena mabatire a 3C, zomwe zimafuna kuti zojambulazo zikhale zowonda komanso zosachita dzimbiri.
- Chakudya Choyambirira:Vacuum phukusi lazakudya zandege, nyemba za khofi zapadera, ndi nyama zapamwamba kwambiri, kumafuna moyo wautali kwambiri wa alumali.
