Papers

Papers are the scientific and technical foundation on which teCH₄⁺ technology is developed. They include works focused on anaerobic digestion, thermal hydrolysis and the energy recovery of organic waste, and reflect the evolution of knowledge from initial research through to commercial implementation.

This section brings together papers directly linked to the development, validation and evolution of the Polanco Process for continuous thermal hydrolysis. The documents present results obtained in pilot plants and at industrial scale, as well as analyses of design, operation and energy efficiency. Their relevance lies in the fact that they reflect the transfer of knowledge from applied engineering to commercial technology.

It includes academic papers developed within the University of Valladolid, where the research line on thermal hydrolysis applied to anaerobic digestion began and was consolidated. These works form the scientific basis for the subsequent development of the technology and address key aspects such as kinetics, solubilisation, energy integration and pretreatment assessment.

This section groups papers related to alternative pretreatment technologies for organic waste, such as thermal, physical or physicochemical treatments other than thermal hydrolysis. This information provides a comparative framework for assessing the advantages, limitations and fields of application of each approach within advanced anaerobic digestion.

It compiles papers focused on anaerobic processes, from both fundamental and applied perspectives. The content includes studies on anaerobic digestion of different substrates, operational optimisation, biogas production and process stability. This section is key to understanding the biological context in which thermal processes are integrated.

This section brings together works related to microaerobic processes, used as an improvement in certain biological systems such as anaerobic digestion. The papers address the influence of low oxygen concentrations on organic matter and the reduction of problematic compounds such as H2S, providing a complementary perspective to strictly anaerobic systems.
