إعداد السماد مع إضافة المواد العضوية Co-Composting هي عملية تحلل هوائي مُتحكم به للمواد العضوية، باستخدام أكثر من مادة للتغذية (حمأة مياه المجاري والمخلفات العضوية الصلبة). حمأة مياه المجاري لديها مُحتوًى عالٍ من الرطوبة والنيتروجين، في حين أن المخلفات الصلبة القابلة للتحلل الحيوي تحتوي على نسبة عالية من الكربون العضوي، ولها خصائص تكتل جيدة (أي أنها تسمح للهواء بالتدفق والسريان). من خلال الجمع بين الاثنين، فإن فوائد كل منهما يُمكن استخدامها لتحسين العملية والمُنتج.
هناك نوعان من التصاميم الخاصة بعملية إعداد السماد مع إضافة المواد العضوية: إما مفتوحة أو مقفولة. في عملية إعداد السماد المفتوحة، يتم تكويم المواد المُمتزجة معًا (الحمأة والمخلفات الصلبة) في أكوام ممتدة على هيئة صفوف للتجفيف (تهوية) Windrows وتُترك لتتحلل؛ ويتم تقليب الأكوام المصفوفة بصورة دورية لتزويدها بالأكسجين، ولضمان أن كل الأجزاء تخضع لنفس المُعالجة الحرارية. أما عملية إعداد السماد المقفولة فإنها تتطلب رطوبة وإمدادات هواء متحكم بها، بالإضافة إلى الخلط الميكانيكي؛ لذلك، فهي ليست مناسبة بشكل عام للمرافق اللامركزية. على الرغم من أن عملية إعداد السماد تبدو كتقنيةٍ بسيطةٍ وخاملة، فإن المرفق الذي يعمل بشكل جيد يتطلب عمليتي تخطيط وتصميم دقيقين لتجنب الإخفاقات.

تكون مرافق إعداد السماد مع إضافة المواد العضوية مُناسبة فقط عندما يكون هناك وفرة من المخلفات الصلبة القابلة للتحلل الحيوي والمفروزة جيدًا. ويجب أن يتم أولًا فرز المواد البلاستيكية والقمامة من المخلفات الصلبة؛ فإذا تم ذلك بشكل جيد، فإنه يُمكن إنتاج مُحسِّنٍ نظيف، وآمن، ومفيد للتربة. ولأن الرطوبة تلعب دور مهمًا في عملية إعداد السماد، فإنه يوصى بالمرافق المُغَطَّأة، خاصةً عندما يكون هناك هطول غزير للأمطار.
بصرف النظر عن الاعتبارات التقنية، فإن إعداد السماد يكون له أهمية فقط إذا كان هناك طلب على المُنتَج )من العملاء الذين يقومون بشراء المُنتَج.( ومن أجل جذب العملاء لشراء المُنتج، فإنّه يجب إنتاج نوعية سمادٍ جيدةٍ باستمرار؛ وهذا يعتمد على الفرز المبدئيّ الجيد، وعلى عملية المُعالجة الحرارية المُحكمة.
يجب أن يقع المرفق بالقرب من مصادر المخلفات العضوية وحمأة مياه المجاري، وذلك لتقليل تكاليف النقل، ولكن يجب -ايضًا- أن تظل بعيدة عن المنازل ومناطق الأعمال حتى لا تسبب الإزعاج. اعتمادًا على المناخ والمساحة المتاحة، فإنه يُمكن تغطية المرفق لمنع التبخر الزائد و/أو توفير الحماية من المطر والرياح. بالنسبة إلى الحمأة منزوعة الماء )المُجففة(؛ فإنَّه يجب إستخدام نسبة تتراوح ما بين 2:1 إلى 3:1 من الحمأة إلى المخلفات الصلبة. أما بالنسبة إلى الحمأة السائلة؛ فإنه يجب استخدام نسبة تتراوح ما بين 1:5 إلى 10:1 من الحمأة إلى المخلفات الصلبة. ويجب أن يكون ارتفاع الأكوام المصفوفة للتجفيف 1 متر على الأقل، ويجب أن يتم وضع طبقة عازلة فوقها باستخدام السماد أو التربة، وذلك لتعزيز التوزيع المتساوي للحرارة داخل الأكوام.
الحفاظ على درجة حرارة تتراوح ما بين 55 إلى 60 درجة مئوية داخل الأكوام يُمكن أن تحد من مسببات الأمراض في الحمأة إلى مستوى آمنٍ للَمسِها والتعامل معها. على الرغم من أن السماد النهائي قد يكون آمنًا في تداوله، فإنه يجب توخّي الحذر -بغض النظر عن المُعالجة السابقة- أثناء التعامل مع الحمأة. إذا وُجِد أن المادة تثير الغبار، فإنه على العمال ارتداء الملابس الواقية واستخدام معدات تنفس مناسبة. كما أن التهوية المناسبة والسيطرة على الغبار تُعَدّ أمورًا مهمة للغاية.
يجب تصميم الخليط بعناية بحيث يحتوي على النسبة الصحيحة من نسبة الكربون إلى النيتروجين، كذلك محتوى الرطوبة الأوكسجين المناسبين. يكون من المُفيد -إذا توفرت الوسائل- مُراقبة تثبيط بويضات ديدان الأمعاء Helminth كمقياس تقريبي لعملية التعقيم.
وجود طاقم مُدرب جيدًا هو أمر ضروري لأعمال التشغيل والصيانة الخاصة بالمرفق. يجب أن يراقب عُمَّال الصيانة جودة المواد الداخلة بحذر، وأن يتتبعوا مسار التدفقات الداخلة والخارجة، والجداول الزمنية للتقليب، وأوقات الإنضاج؛ لضمان الحصول على مُنتج عالِ الجودة. كما يجب التحكم والمتابعة لأنظمة التهوية الإجبارية بعناية.
يحب القيام بالتقليب بشكل دوري باستخدام إما مُعِّدة تقليب ميكانيكية )لودر أمامي، أو تركس( أو باليد. تساعد المفارم المتينة -الخاصة بتقطيع الأجزاء الكبيرة من المخلفات الصلبة )مثل فروع الأشجار(- ومقلّبات الأكوام على تحسين عملية إعداد السماد، وعلى تخفيض العمالة اليدوية، وضمان تجانس المُنتَج النهائي.

The earthquake that struck Haiti in January 2010 and the cholera epidemic that followed from October 2010, resulted in one of the largest humanitarian relief efforts in history. Many of the internally displaced persons camps were located in urban neighbourhoods with high groundwater, making onsite sanitation extremely difficult. In response to these unique conditions a small local organization, SOIL, partnered with Oxfam Great Britain to pilot urine diversion EcoSan toilets in camps throughout Port-au-Prince. This briefing paper covers this pilot project from March 2010 through March 2012. During that 2-year period, SOIL’s toilets served over 20,000 people and treated more than 400,000 gallons of human waste, converting it to rich compost.
