In tests, the acoustic properties of the material resembled those of expensive, high-quality mahogany and were slightly superior to those of marupa, a wood used in Brazil to make certain types of guitars. Development of this instrument with an ecological footprint was part of the final project for the industrial design program Novaes completed in 2014 at the School of Fine Arts at the Federal University of Rio de Janeiro (UFRJ). The material, which combines an epoxy resin base with the malt waste, was presented at the 12th Brazil Design Research and Development Conference held in October 2016. \u201cThe idea is to replace the epoxy polymer base with a castor oil-based resin in order to make the composite material completely sustainable,\u201d says Novaes, who has filed a patent application for the compound with the Brazilian Industrial Property Institute (INPI).<\/p>\n","protected":false},"excerpt":{"rendered":"A guitar made with cereal malt waste from beer-making","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[243,248,262],"coauthors":[785],"class_list":["post-239273","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-innovation","tag-music","tag-sustainability"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/239273","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=239273"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/239273\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=239273"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=239273"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=239273"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=239273"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
