Bu çalışma, Türkiye’de 2023 yılı verileri baz alınarak kesimhanelerde oluşan kan atıklarının biyogaz üretim potansiyelini, enerji değerini ve çevresel faydalarını ortaya koymayı amaçlamaktadır. Hesaplamalar, Türkiye İstatistik Kurumu (TÜİK) verileri ve literatürden elde edilen teknik parametreler kullanılarak, alanda kabul görmüş temel yaklaşımlara dayalı olarak yapılmıştır. 2023 yılı verilerine göre, Türkiye’de yıllık yaklaşık 83375 ton toplanabilir kan atığı potansiyeli olduğu hesaplanmıştır. Bu potansiyelin değerlendirilmesiyle yıllık yaklaşık 6.9 milyon m³ metan üretilebileceği, bunun da 31.1 GWh elektrik enerjisine eşdeğer olduğu belirlenmiştir. Bu dönüşümün, kömür bazlı elektrik üretiminin yerini alması senaryosuyla, yıllık yaklaşık 85486 ton CO₂ eşdeğeri emisyon azaltımı sağlayabileceği öngörülmüştür. Kan atığının yüksek protein içeriği ve düşük C/N oranı, tek başına anaerobik sindirimde amonyak inhibisyonuna yol açtığından, bu potansiyelin ancak büyükbaş hayvan gübresi gibi karbon zengini atıklarla birlikte ko-fermantasyon yoluyla gerçekleştirilebileceği vurgulanmıştır. Bu çalışma, kan atıklarının Türkiye’nin yenilenebilir enerji portföyüne ve döngüsel ekonomi hedeflerine entegrasyonu için stratejik bir çerçeve sunmaktadır.

Assessment of the biogas potential of cattle and sheep farm animal slaughterhouse blood waste in Türkiye: Impact on energy production and CO₂ emission reduction

Öz

This study aims to reveal the biogas production potential, energy value, and environmental benefits of slaughterhouse blood waste generated in Turkey, based on 2023 data. Calculations were based on a previously developed methodology, using data from the Turkish Statistical Institute (TURKSTAT) and technical parameters derived from the literature. According to 2023 data, it was calculated that there is an annual potential of approximately 83375 tons of collectible blood waste in Turkey. It was determined that the valorization of this potential could yield approximately 6.9 million m³ of methane annually, equivalent to 31.1 GWh of electrical energy. It is projected that this conversion, by replacing coal-based electricity generation, could provide an annual emission reduction of approximately 85486 tons of CO₂ equivalent. Due to the high protein content and low C/N ratio of blood waste, which leads to ammonia inhibition in mono-anaerobic digestion, it is emphasized that this potential can only be realized through co-digestion with carbon-rich wastes such as animal manure. This study provides a strategic framework for the integration of blood waste into Turkey’s renewable energy portfolio and circular economy goals.
