I-Biodegradable glitter inokuliguqula ishishini lezithambiso.
Ubomi bugcwele ukupakishwa okukhazimlayo, iibhotile zokuthambisa, izitya zeziqhamo kunye nokunye, kodwa uninzi lwazo zenziwe ngezinto ezinetyhefu nezingenakugcinwa zinegalelo kungcoliseko lweplastiki. Kungekudala, abaphandi beYunivesithi yaseCambridge e-UK baye bafumanisa indlela yokudala i-glitter ezinzileyo, engeyona inetyhefu kunye ne-biodegradable evela kwi-cellulose, ibhloko enkulu yokwakha yeendonga zeeseli zezityalo, iziqhamo kunye nemifuno. Amaphepha anxulumeneyo apapashwa kwijenali yeMathiriyeli yeNdalo ngomhla we-11. Yenziwe kwi-cellulose nanocrystals, le glitter isebenzisa umbala wesakhiwo ukuguqula ukukhanya ukuvelisa imibala eqaqambileyo.
