Biogas production from buffalo manure significantly reduces environmental impact compared to direct landspreading

Frontiers in Food Science and Technology · 2026

Key Findings

01Biogas production (S2) reduced global warming potential by 59%, acidification by 71%, and eutrophication by 51% compared to landspreading (S1).
02Biogas production (S2) led to increased human toxicity impacts due to feedstock transportation and agricultural inputs.
03Substituting input crops like triticale grains with wheat bran further improved the environmental performance of S2.
04Overall, S2 outperformed S1 in most environmental impact categories.

Application

Design takeaway

How to apply

When designing or evaluating waste management solutions for livestock farms, conduct a comparative LCA to quantify environmental benefits, paying close attention to energy recovery potential and feedstock supply chains.

Project actions

01When evaluating different waste management options, use LCA to quantify environmental impacts.
02Consider the entire life cycle, from raw material sourcing to final disposal or reuse.

Method & Evidence

AimTo compare the environmental impacts of two buffalo manure management systems: direct landspreading versus biogas production, and to recommend sustainable practices for farmers.

MethodComparative Life Cycle Assessment (LCA)

ProcedureA gate-to-grave LCA was conducted using primary data from a southern Italian buffalo farm. The functional unit was one ton of buffalo manure. Two systems were evaluated: S1 (direct application to field) and S2 (biogas production). Environmental impacts were assessed across various categories, and sensitivity analysis was performed by substituting input crops.

ContextAgricultural waste management, specifically buffalo manure in southern Italy.

Variables

IV["Manure management strategy (direct landspreading vs. biogas production)"]

DV["Global warming potential","Acidification","Eutrophication","Human toxicity"]

CV["Type of manure (buffalo)","Functional unit (1 ton of manure)","Geographical location (southern Italy)","Farm type (buffalo farm producing D.O.P. mozzarella)"]

Strengths & Limitations

Strengths

+Uses a robust methodology (LCA) for environmental assessment.
+Employs primary data directly from a relevant farm.
+Provides practical recommendations for farmers.

Limitations

The specific environmental benefits might differ based on the type of livestock, local climate, and the efficiency of the biogas technology used. The study focuses on a single farm, so generalizability might be limited.

Reliability & validity

Reliability would be enhanced by repeating the LCA with data from multiple farms and different regions. Validity is supported by the use of a standardized LCA methodology and primary data, but the specific impact assessment methods used can influence results.

Think critically

How can the increased human toxicity impacts associated with biogas production be effectively mitigated through design interventions in feedstock sourcing and transportation?

Design Principles

"Waste valorization through energy recovery offers significant environmental advantages over direct disposal."

This research provides a clear, data-driven comparison of two common manure management strategies, highlighting the environmental advantages of adopting biogas technology. For designers and engineers working in agricultural systems or waste management, this insight informs the development of more sustainable practices and technologies.

What This Means for Your Design

Turning buffalo poop into biogas is much better for the planet than just spreading it on fields, as it creates less pollution and greenhouse gases. However, how you get the stuff to make the biogas matters too.

How to use in your project

1.Use this study as a benchmark for comparing the environmental impacts of different waste management strategies in your design project.
2.Cite this research when discussing the benefits of biogas production or the importance of LCA in environmental design.

Paragraph starter

A life cycle assessment of buffalo manure management strategies revealed that biogas production significantly outperforms direct landspreading in terms of global warming potential, acidification, and eutrophication. While biogas production can increase human toxicity impacts due to feedstock transportation and inputs, optimizing feedstock composition, such as using wheat bran instead of grains, can further enhance its environmental performance, making it a preferable choice for sustainable waste management in livestock operations.
