<p>PurposeoftheGuidelineTheMinistryofEnvironment,inconjunctionwiththeMinistryofAgricultureandLands,hasdevelopedthisguidelinetoassistonfarmanaerobicdigestionproponentsinapplyingforawastedischargeauthorizationundertheEnvironmentalManagementActandWasteDischargeRegulation.Theguidelineincludesanintroductiontotheanaerobicdigestiontechnology,thewastedischargeauthorization(permitting)process,andguidanceonthewastestreamstobeidentifiedintheapplicationpackage.Theguidelinealsoprovidesalistofacceptablefeedstocksforonfarmanaerobicdigestionandrecommendationsfornutrientmanagementplanning,sampling,analysisandbestmanagementpractices.InadditiontoaMinistryofEnvironmentwastedischargeauthorization,onfarmanaerobicdigestionfacilitiesmayalsorequireauthorizationfromlocalgovernmentsandtheAgriculturalLandCommission,iflocatedwithintheAgriculturalLandReserve.Theseadditionalprocessesarebrieflyoutlinedintheguideline.WhatisAnaerobicDigestion?Anaerobicdigestionisthebiologicalprocessbywhichorganicmatter(e.g.,manure),isbrokendownintheabsenceofoxygen,producingrawbiogasandotherbyproducts.Therawbiogasismostcommonlyusedtogenerateelectricitythroughcogenerationorupgradedtonaturalgas.Otherbenefitsofanaerobicdigestionincludereductionsinmanurerelatedodours,pathogens,andgreenhousegas(GHG)emissions.
