What is more difficult is making it common practice. The report estimates more than 80% of the world\u2019s wastewater goes into the environment untreated. In the developing world, where there is a lack of expertise, funding and infrastructure, it is more than 95%.<br>This is a&nbsp;<strong>critical issue<\/strong>&nbsp;because&nbsp;<strong>it means that the world\u2019s fresh water is being polluted<\/strong>, reducing the availability of a precious resource that is already under strain because of global warming and a growing population.<\/p>\n\n\n\n<p>It is also a matter of health. In 2012, more than 800,000 deaths were caused by contaminated drinking water, poor washing of hands and lack of proper sanitation services, according to the report, which was published in March under the title \u201c2017 World Water Development Report\u201d.<\/p>\n\n\n\n<p>Then there is the damage to the environment.&nbsp;<strong>Untreated wastewater that is discharged into seas and oceans can deprive their water of oxygen<\/strong>, creating dead zones. The report speaks of 245,000 square kilometres of such zones.<br>All of this makes achieving one of the U.N. Sustainable Development Goals under the 2030 Agenda for Sustainable Development seem a remote probability: halving the proportion of untreated wastewater and increasing the recycling and reuse of it.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"602\" height=\"343\" src=\"https:\/\/www.webuildvalue.com\/wp-content\/uploads\/impianto-di-trattamento-delle-acque-reflue.jpg\" alt=\"impianto-di-trattamento-delle-acque-reflue\" class=\"wp-image-156954\" srcset=\"https:\/\/www.webuildvalue.com\/wp-content\/uploads\/impianto-di-trattamento-delle-acque-reflue.jpg 602w, https:\/\/www.webuildvalue.com\/wp-content\/uploads\/impianto-di-trattamento-delle-acque-reflue-300x171.jpg 300w\" sizes=\"auto, (max-width: 602px) 100vw, 602px\" \/><figcaption>Sewage treatment plant<\/figcaption><\/figure>\n\n\n\n<p>The report makes it clear what needs to be done:&nbsp;<strong>reduce pollution at the source; remove contaminants from wastewater flows<\/strong>; reuse reclaimed water; and recover useful by-products. \u00abThese four actions generate social, environmental and economic benefits for all society\u00bb, it says. \u00abWastewater flows contain a number of useful materials, such as nutrients, metals and organic material that, much like the water itself, can be extracted and used\u2026 for other productive purposes\u00bb.<\/p>\n\n\n\n<p>In terms of health and the environment, the benefits of managing human waste are quantifiable, the report says. \u00abFor every US$ 1 spent on sanitation, the estimated return to society is US$ 5.5\u00bb.<br>Examples of efforts to treat wastewater abound.

In a case study, the report recounts how Carbery did this by putting whey &#8211; the by-product of making cheese &#8211; through microfiltration and reverse osmosis and sending the lactose \u2013 a main ingredient of whey &#8211; to a fermenter to be turned into beer before sending it to a distillation system to produce an ethanol product for the bioethanol fuel market. \u00abAll the bioethanol in Ireland comes from this one plant and (Ireland) is the only European country not using sugarcane-based ethanol from Brazil\u00bb, it says.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There is a dairy company in Ireland that&nbsp;treats its wastewater so it can be used to make beer and ethanol.In South Africa,&nbsp;water from three mines is drunk by local residents&nbsp;after being treated at a plant.Dye and bleach producers in India are starting&nbsp;to reuse their discharges&nbsp;in order to leave more fresh water to farmers.These are&nbsp;but a [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":116962,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[33],"tags":[19003,19012,12216],"yst_prominent_words":[5039,5038,5035,4711,5044,676,1587,5040,3858],"class_list":["post-520794","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-megatrends","tag-global-investments","tag-hydraulic-risk","tag-water"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/posts\/520794","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/comments?post=520794"}],"version-history":[{"count":10,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/posts\/520794\/revisions"}],"predecessor-version":[{"id":541260,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/posts\/520794\/revisions\/541260"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/media\/116962"}],"wp:attachment":[{"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/media?parent=520794"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/categories?post=520794"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/tags?post=520794"},{"taxonomy":"yst_prominent_words","embeddable":true,"href":"https:\/\/www.webuildvalue.com\/en\/wp-json\/wp\/v2\/yst_prominent_words?post=520794"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
