Her bor godt 500 familier i sm\u00e5 huse lavet af mursten, tin og mudder. De ligger spredt mellem lavtst\u00e5ende palmer.\u00a0<\/p>\n\n\n\n<p style=\"font-size:15px\">L\u00e6s ogs\u00e5: <a href=\"https:\/\/nytaenk.dk\/explainer-hvad-er-biogas\/\">EXPLAINER: Hvad er biogas?<\/a><\/p>\n\n\n\n<p>Flere af husstandene har et \u00e5bent skur til k\u00f8er, som hver producerer 10 til 12 kilo g\u00f8dning om dagen. G\u00f8dning der f\u00f8r i tiden blev smidt p\u00e5 de omkringliggende marker til stor irritation for naboerne.<\/p>\n\n\n\n<p>I mange \u00e5r har byen ikke haft nogle energikilder. Derfor har kvinderne lavet mad ved at br\u00e6nde tr\u00e6 under komfuret. En proces der oser meget, giver d\u00e5rlig hygiejne med beskidte k\u00f8kkenredskaber samt irriterer \u00f8jne og hals.&nbsp;&nbsp;<\/p>\n\n\n\n<p>NyT\u00e6nk er taget ti landsbyen for at se, hvordan installationen af et 2,4 kubikmeter stort biogasanl\u00e6g har forbedret forholdene.

Han fort\u00e6ller, at hvis en ejer for eksempel har fem k\u00f8er, giver det biogas nok til, at to husholdninger kan lave mad fire timer hver dag.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Udfordringerne ved at installere biogasanl\u00e6g i afsidesliggende landsbyer\" src=\"https:\/\/player.vimeo.com\/video\/744460307?dnt=1&amp;app_id=122963\" width=\"500\" height=\"281\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture; clipboard-write; encrypted-media; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>\u201cProcessen starter med at putte organisk materiale i indl\u00f8bet. Om morgenen samler beboerne cirka 65 kilo kom\u00f8g, mikser det med lige dele vand og kommer det i r\u00e5dnetanken, hvor det bliver nedbrudt i et iltfrit milj\u00f8. Resultatet frig\u00f8r 60 &#8211; 70 procent metan gas, som transporteres ind i k\u00f8kkenerne gennem et fleksibelt r\u00f8r\u201d, uddyber Hague.<\/p>\n\n\n\n<p>Alt hvad beboerne skal g\u00f8re er at trykke p\u00e5 ventilen, n\u00e5r de gerne vil bruge deres gaskomfur.<\/p>\n\n\n\n<p>I samme proces \u00f8ges gastrykket i r\u00e5dnetanken s\u00e5 betydeligt, at gyllen presses over i det hydrauliske kammer, hvor det langsomt udskilles til to udgravede huller ved siden af.&nbsp;&nbsp;<\/p>\n\n\n\n<p><strong><em>\u201cF\u00f8r vi installerede biogasanl\u00e6gget, var der ingen systemisk affaldsh\u00e5ndtering.

Processen med at omdanne kom\u00f8g til gas og g\u00f8dning er ens uanset typen af anl\u00e6g.<\/p>\n\n\n\n<pre class=\"wp-block-verse has-ast-global-color-5-color has-ast-global-color-1-background-color has-text-color has-background has-small-font-size\"><strong>FAKTA:<\/strong> \u201cHydraulisk\u201d refererer til systemer med v\u00e6sker, der overf\u00f8rer tryk.

For det f\u00f8rste er det sv\u00e6rt at transportere r\u00e5materialerne over lange distancer uden ordentlige vejforhold, og for det andet fyldes jordhullerne under udgravning ofte med vand i regns\u00e6sonen.<\/p>\n\n\n\n<p>Det er Grameen Shakti, der s\u00e6lger anl\u00e6gget til de lokale beboere. Prisen er p\u00e5 40,000 taka (lidt over 3.000 DKK), og der er meget f\u00e5 vedligeholdelsesomkostninger, fort\u00e6ller Abdul Arif, som er projetleder ved organisationen.<\/p>\n\n\n\n<p>I alt har Grameen Shakti installeret godt 4.000 biogasanl\u00e6g i Mymensingh regionen, som er en oplagt aftager, fordi flere familier lever af landbrug. Derfor har de meget g\u00f8dning at g\u00f8re brug af. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>NyT\u00e6nk er taget ti landsbyen for at se, hvordan installationen af et 2,4 kubikmeter stort biogasanl\u00e6g har forbedret forholdene.<\/p>\n","protected":false},"author":1,"featured_media":4361,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[3],"tags":[7],"class_list":["post-4360","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-energi","tag-biogas"],"_links":{"self":[{"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/posts\/4360","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/comments?post=4360"}],"version-history":[{"count":0,"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/posts\/4360\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/media\/4361"}],"wp:attachment":[{"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/media?parent=4360"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/categories?post=4360"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bun.nytaenk.dk\/index.php\/wp-json\/wp\/v2\/tags?post=4360"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
