02Investigate the typical composition and properties of the waste material (e.g., animal manure) to understand potential processing challenges.

Method & Evidence

AimTo review and assess the potential of thermochemical conversion technologies for the sustainable valorisation of animal manures into valuable products and energy.

MethodLiterature Review

ProcedureThe study involved a comprehensive review of existing literature on thermochemical conversion technologies (pyrolysis, combustion, gasification) applied to animal manure. It examined manure characterization, technology modelling and optimization, and life cycle assessments (LCA) to understand recent trends and challenges.

ContextAgricultural waste management and bioenergy production

Variables

IVThermochemical conversion technology type (e.g., pyrolysis, gasification, combustion)

DVCalorific value of produced bio-oil, yield of valuable products (bio-oil, syngas, biochar), environmental impact (e.g., GHG emissions reduction), economic viability.

CVType of animal manure, moisture content, ash content, operating parameters of the conversion technology (temperature, pressure, residence time).

Strengths & Limitations

Strengths

+Provides a comprehensive overview of multiple thermochemical conversion technologies.
+Includes an assessment of life cycle analysis (LCA) for sustainability evaluation.

Limitations

The commercial viability and scalability of these technologies are still under development, meaning practical implementation might require significant investment and further engineering.
