A research team at the Institute of Industrial Science at The University of Tokyo has figured out how to make durable, strong and still-edible construction materials out of food.<\/p>\n<p class=\"speakableTextP2\">Pulverized cabbage leaves, seaweed and banana peels might not be as thrilling as gingerbread and pastries, but they could be part of a recipe for sustainable building products.<\/p>\n<p>&#8220;Our goal was to use seaweed and common food scraps to construct materials that were at least as strong as concrete,&#8221;\u00a0<a href=\"https:\/\/www.iis.u-tokyo.ac.jp\/en\/news\/3567\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" data-component=\"externalLink\">said Yuya Sakai<\/a>, a sustainable construction materials specialist and senior author of an upcoming study on the materials, in a University of Toyko statement on Tuesday. &#8220;But since we were using edible food waste, we were also interested in determining whether the recycling process impacted the flavor of the original materials.&#8221;<\/p>\n<p>The team tried a heat-pressing technique usually used to compress wood powder into construction materials. Instead of wood, they vacuum-dried and then pulverized a variety of food waste items, including onion and fruit peels, as well as cabbage.<\/p>\n<p>&#8220;The processing technique involved mixing the food powder with water and seasonings, then pressing the mixture into a mold at high temperature,&#8221; the university said. All of the resulting products, with the exception of the pumpkin peel, passed the team&#8217;s tests for strength.<\/p>\n<p>The researchers figured out a workaround for the pumpkin issue. &#8220;We also found that Chinese cabbage leaves, which produced a material over three times stronger than concrete, could be mixed with the weaker pumpkin-based material to provide effective reinforcement,&#8221;\u00a0<a href=\"https:\/\/www.iis.u-tokyo.ac.jp\/en\/news\/3567\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" data-component=\"externalLink\">said Kota Machida<\/a>, a collaborator on the project.<\/p>\n<p>The molded materials remained edible, though the team didn&#8217;t say if they were hard to chew. Even leaving the materials exposed to air for four months didn&#8217;t change the taste, and there were no issues with rot or insects.<\/p>\n<p>The development of potentially munchable materials is still in an early stage, but perhaps some day you could build a shelter and then snack on it when it&#8217;s no longer needed. It would bring the witch&#8217;s house into the modern age.<\/p>\n<p><a href=\"https:\/\/www.cnet.com\/news\/scientists-turn-cabbage-into-construction-material-stronger-than-concrete\/\" target=\"_blank\" rel=\"noopener\">Read more&#8230;.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists have turned cabbage into construction material stronger than concrete and it turns out scraps from onions and fruit also make for durable building products.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-30154","post","type-post","status-publish","format-standard","hentry","category-sector-newsblog"],"_links":{"self":[{"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=\/wp\/v2\/posts\/30154","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=30154"}],"version-history":[{"count":1,"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=\/wp\/v2\/posts\/30154\/revisions"}],"predecessor-version":[{"id":30156,"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=\/wp\/v2\/posts\/30154\/revisions\/30156"}],"wp:attachment":[{"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=30154"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=30154"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/newsblogs.ihbc.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=30154"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
