It represents a massive leap forward for the region\u2019s renewable energy sector and circular economy.<\/p>\n\n\n\n<p>The scale of this\u00a0Estonian biogas project\u00a0showcases AAT\u2019s advanced engineering. To ensure maximum operational reliability and high-efficiency methane yield.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Plant Configuration &amp; Digester Volume<\/strong><\/h3>\n\n\n\n<p>The infrastructure is divided into two parallel processing lines, each consisting of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>1 Mix Tank<\/strong>&nbsp;for substrate homogenization<\/li>\n\n\n\n<li><strong>3 Digesters<\/strong>&nbsp;for primary anaerobic digestion<\/li>\n\n\n\n<li><strong>1 Post-Digester<\/strong>&nbsp;for maximum gas extraction<\/li>\n<\/ul>\n\n\n\n<p>Key Technical Data:\u00a0The plant operates a total of\u00a06 digesters, with a volume of\u00a03,880 m\u00b3\u00a0each. (Dimensions: \u00d8 26m x 8 m), providing the massive retention capacity needed for stable biological processes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Sustainable Agricultural Waste-to-Energy Processing<\/strong><\/h3>\n\n\n\n<p>As a major environmental milestone for Saaremaa, the plant is engineered to process nearly\u00a0800 tons per day\u00a0of locally sourced solid and liquid agricultural waste.<\/p>\n\n\n\n<p>By recycling organic waste streams, AAT\u2019s technology reduces greenhouse gas emissions from local farming while producing clean, scalable energy. The primary feedstocks include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Animal Manure:<\/strong>&nbsp;Cow and pig manure<\/li>\n\n\n\n<li><strong>Agricultural Residuals:<\/strong>&nbsp;Feed rests and grass silage<\/li>\n\n\n\n<li><strong>Industrial Organic Waste:<\/strong>&nbsp;Flotation sludge and whey<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Biomethanation and Bio-Fertilizer Output Capacity<\/strong><\/h3>\n\n\n\n<p>The successfully commissioned facility delivers high-performing environmental and economic metrics, converting raw waste into high-value green energy commodities:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Raw Biogas Production 1,460 Nm\u00b3\/h<\/strong><\/li>\n\n\n\n<li><strong>Biomethane Equivalent<\/strong>&nbsp;<strong>880 Nm\u00b3\/h<\/strong>&nbsp;(after upgrading)<\/li>\n\n\n\n<li><strong>Organic Fertilizer Production<\/strong>&nbsp;<strong>756 t\/d<\/strong>&nbsp;(nutrient-rich digestate)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Grid-Ready Biomethane Upgrade<\/strong><\/h3>\n\n\n\n<p>The raw biogas generated on-site is continuously upgraded into high-grade&nbsp;<strong>biomethane<\/strong>. This green gas is ready for injection into the national gas grid or for use as a sustainable transport fuel (Bio-CNG\/Bio-LNG).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Closing the Loop with Eco-Friendly Fertilizer<\/strong><\/h3>\n\n\n\n<p>In addition to clean energy, the plant outputs\u00a0a high-quality organic fertilizer. This digestate is returned to local Estonian farmers, replacing synthetic fertilizers and enriching the soil via a perfect circular economy loop.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Partner with AAT for Advanced Biogas Solutions<\/strong><\/h3>\n\n\n\n<p>The successful launch of the Saaremaa project reinforces AAT\u2019s position as a leading international developer of industrial-scale\u00a0biogas plants in Europe.
