Nanga bwanji za msika wapadziko lonse wa zikopa zopangidwa ndi zamoyo?

Zinthu zopangidwa ndi bio zili mu gawo loyamba ndipo kafukufuku ndi chitukuko zikupita patsogolo kuti zigwiritsidwe ntchito kwambiri chifukwa cha makhalidwe ake obwezerezedwanso komanso ochezeka ndi chilengedwe. Zinthu zopangidwa ndi bio zikuyembekezeka kukula kwambiri kumapeto kwa nthawi yolosera.

Chikopa chopangidwa ndi bio chimapangidwa ndi polyester polyols, yopangidwa kuchokera ku bio-based succinic acid ndi 1, 3-propanediol. Nsalu ya chikopa chopangidwa ndi bio ili ndi 70 peresenti ya zinthu zongowonjezedwanso, imapereka magwiridwe antchito abwino komanso chitetezo ku chilengedwe.

Chikopa chopangidwa ndi bio chimapereka kukana kukanda bwino ndipo chili ndi malo ofewa poyerekeza ndi zikopa zina zopangidwa ndi bio. Chikopa chopangidwa ndi bio sichili ndi phthalate, chifukwa cha izi, chavomerezedwa ndi maboma osiyanasiyana, chotetezedwa ku malamulo okhwima ndipo chimagawana gawo lalikulu pamsika wapadziko lonse wa zikopa zopangidwa ndi bio. Ntchito zazikulu za chikopa chopangidwa ndi bio ndi nsapato, matumba, zikwama, chivundikiro cha mpando, ndi zida zamasewera, pakati pa zina.
