TSMC leads global chip-mak­ers in sav­ing wa­ter

The China Post - - TAIWAN BUSINESS -

Tai­wan Semi­con­duc­tor Man­u­fac­tur­ing Co. (TSMC, ), the world’s largest con­tract chip­maker, uses 5.66 liters of wa­ter for ev­ery square cen­time­ters of wafer pro­duced, sav­ing sev­eral times more wa­ter than ri­vals in the United States, Ja­pan and South Korea, com­pany data showed Thurs­day.

For the same size of wafer pro­duced, TSMC saves 3 times more wa­ter than man­u­fac­tur­ers in the U.S., twice as much as those in Ja­pan and 1.5 times more wa­ter than com­pa­nies in South Korea, which are home to the world’s ma­jor chip-mak­ers, TSMC data showed.

It noted one of the ways it is able to con­serve wa­ter is by reusing wa­ter.

“TSMC uses each drop of wa­ter 3.5 times, and the com­pany this year aims to in­crease the re­cy­cling rate to 4 times,” said Tony Chen, a sec­tion of­fi­cial of Fab 15, one of the comp­may’s three fa­cil­i­ties that pro­duce 12-inch wafers, in Cen­tral Tai­wan Science Park in Taichung.

TSMC re­cy­cles 87.5 per­cent of its used wa­ter and pro­duces 240,000 met­ric tons of re­cy­cled wa­ter ev­ery day, or 87.6 mil­lion met­ric tons a year, Chen said.

The com­pany has been com­mit­ted to de­vel­op­ing new wa­ter re­cy­cling tech­nol­ogy with the aim of mak­ing the best use of wa­ter.

TSMC also spends some NT$800 mil­lion (US$25.5 mil­lion) on wa­ter sav­ing fa­cil­i­ties each year, said Arthur Chuang, a sec­tion of­fi­cial of Fab 15.

Tourists Back Tai­wan’s Wa­ter

Con­ser­va­tion Prac­tices

Vis­i­tors from Europe and the U. S. are most sup­port­ive of lo­cal ho­tels’ wa­ter con­ser­va­tion prac­tices, ac­cord­ing to an ex­ec­u­tive of the Lan­dis Ho­tel Taipei.

The ex­ec­u­tive said that since 2009, the Lan­dis has at­tached great im­por­tance to wa­ter con­ser­va­tion and has in­stalled sen­sor­con­trolled taps in its public toi­lets which use 30 per­cent less of wa­ter than or­di­nary taps.

In ad­di­tion, the ex­ec­u­tive said, the ho­tel puts in ev­ery room a card re­mind­ing guests who stay for more than two nights that their bed sheets and tow­els will be changed ev­ery­day only if they put the card up­side down on their bed each morn­ing.

Oc­cu­pants who choose not to change their bed­ding will get a credit of NT$100 (US$3) against their bill each day, said the ex­ec­u­tive.

The prac­tice is fol­lowed by all of the six ho­tels op­er­ated by the Lan­dis group across Tai­wan, said the ex­ec­u­tive.

Euro­pean and Amer­i­can guests seem most sup­port­ive of such mea­sures to con­serve wa­ter, fol­lowed by Ja­panese tourists and Tai­wan tourists in that or­der, said the anony­mous ex­ec­u­tive.

Wa­ter con­ser­va­tion is en­cour­aged as Tai­wan launched a new phase of wa­ter ra­tioning this week to deal with its worst drought in years. In­ad­e­quate rain­fall, sed­i­ment buildup in reser­voirs, leaky pipes and waste­ful con­sumers have led to wa­ter lev­els in reser­voirs drop­ping to 50 per­cent or less of their ca­pac­ity.


Tourists can be seen walk­ing around the Shih­men Reser­voir ( ), yes­ter­day. While a cold front brought a new wave of rain­fall, as of 5 p.m., the wa­ter level was still 25.16 me­ters short of full ca­pac­ity. It cur­rently sits at 25 per­cent of its ca­pac­ity.
