Họ làm bia nhẹ như thế này ư?

Beer uses a lot of water. In fact, the drink is more than 90 per cent H2O.

So in a world facing an increasing threat (mối đe dọa, sự hăm dọa) of water shortages (thiếu nước) due to the climate crisis (khủng hoảng khí hậu), Singapore has decided to do try something different to tackle the issue.

And it’s all to do with sewage.

Singapore’s water agency is rolling out a craft beer that is mostly made from wastewater (nước thải).

The sewage is treated to become “ultra-clean” water, before it is used to create the tropical blonde ale.

So instead of using valuable water supplies, the 95 per cent water part of the beer is all recycled.

Singapore already treats sewage to create NEWater, which then gets pumped back into the system and is mainly used for industrial and air-conditioning (điều hòa) purposes (mục đích).

Its national water board says it does this to cushion water supply against dry weather.

During dry periods, the recycled sewage gets added to reservoirs, before the water there is treated and used as tap water.
