Research & Development

Anticipating technological developments

APESA has been working on Research and Innovation for several years to anticipate technological developments in waste and biomass recovery. Thus, APESA has taken part in various European and national R & D projects.

This choice allows us to constantly acquire new skills, to propose innovative approaches and customized tests to our public and private clients.

The different teams of APESA work together to provide a comprehensive response to their clients. Thus, in addition to the skills of the Valorization team, we can carry out technico-economic, environmental and societal studies of valorization processes and organize the dissemination of information or networking.

The research services performed by APESA are eligible for the RESEARCH TAX CREDIT

Our services

APESA offers a range of R&D services to support you in the innovation and the development of tomorrow’s technologies in terms of energy, biomass and waste recovery.

Among our services:

  • Documentary monitoring in environmental fields.
  • Customized experiments.
  • Reports writing, scientific and popular articles.
  • Setting up European and national R&D projects.
  • Animate, communicate, develop R&D networks.
Our research axes and themes

Topic 1 : Storage and biomass pretreatment 

  • Pre/Post-treatment of biomasses (mechanical, thermo-chemical, enzymatic).
  • Simulation of the biomass storage (silage, rewinding, tanks ...)
  • Study of pretreatment and storage on physico-chemical properties, carbon losses and methanogenic potential. 
  • Impact of pretreatments on the agronomic quality and digestats innocuity.


Topic 2 : Monitoring and improvement of the anaerobic digestion process

  • Dry, CSTR, and UASB anaerobic digestion in mesophilic and thermophilic conditions at pilot-scale.
  • Performances improvement on recalcitrant biomasses.  
  • Development of multi-indicator analysis tools based on SPIR technology allowing to follow both the performance and stability criteria of anaerobic digesters.
  • Biogas treatment by innovative processes.


Topic 3 : Digestates valorization

  • Composting of digestates: effect of operational conditions and bulking agent used.
  • Agronomic and innocuity properties of digestates and composts.
  • New ways of digestats valorization (microalgae cultures, thermo-chemical processes by pyrolysis and gasification).


Topic 4 : Anaerobic digestion sustainability

  • Technical-economic study.
  • Environmental study (LCA, carbon balances) and societal acceptability.
  • Development of diagnostic tool.


Topic 5 : Treatment of waste water and industrial effluents

The APESA Platform also participates in R&D programs on the treatment of wastewater and industrial effluents by various processes.

  • Evaluation of aerobic biodegradability of mechanical engineering effluents.
  • Evaluation of the capacity of plant-based filters to remove various compounds (especially hydrocarbons) in water.
  • Evaluate the ability of microalgae to purify saline and wastewaters effluents and to study the potential for valorization into algal biomass.
