Instituto para el Desarrollo de Energías y Materiales Alternativos IDEMA

College of Sciences and Engineering
About us

At the Institute for the Development of Alternative Energies and Materials - IDEMA we believe in a circular economy, where all matter and energy can and should be harnessed, and where it is the responsibility of human beings to use the planet's resources in a responsible and sustainable way. For this reason, we investigate new ways of using waste in order to generate innovative materials and chemical precursors substitutes for traditional raw materials such as oil, coal, or natural gas. Based on this concept we develop technologies to obtain economically profitable, socially responsible, and with a positive environmental impact, innovative biomaterials, alternative energy sources, and green chemical precursors.


The objective at IDEMA is to investigate new sources of raw material from biomass and waste of all kinds to develop technologies for their use as alternative energy sources, biomaterials, or chemical precursors for their subsequent application in production processes.

The specific objectives are:

To investigate chemical, thermo-chemical, physical, mechanical, or biological processes for the conversion of biomass, organic waste, and other industrial, agro-industrial, and municipal by-products.
Apply engineering and green chemistry concepts to generate new technologies from biomass and other industrial waste to obtain:

  • Investigate chemical, thermochemical, physical, mechanical or biological processes for the conversion of biomass, organic waste and other industrial, agro-industrial and municipal by-products.
  • Generate new biomaterial technologies for biomedical and biotechnological applications.
  • Investigate processes of conversion of biomass and organic residues into chemical precursors and alternative materials by biological, chemical, thermochemical or physical processes.
  • Develop new alternative energy sources from residual biomass and industrial, agro-industrial, urban, and other residues.

History and Background

The Alternative Energy Development Laboratory (LaDEA) was created in 2008 with the aim of researching and developing new technologies in the field of waste management in order to obtain second generation alternative and renewable energy, or secondary raw materials. In 2016 the name was changed to IDEMA to formalize its existence as a research institute within the USFQ.

To date, 60 Engineering theses or degree projects have been carried out, and 10 consultancies and research and development projects with external national or international funds.

At IDEMA there are currently three lines of research:

  • Bioprocesses,
  • Biomaterials
  • Thermo-chemical processes
Academic staff

Investigate alternative raw material sources and develop new processes for the generation of energy and alternative materials, giving high added value to waste and by-products from the Ecuadorian agro-industry, in order to contribute to the efficient management of waste, reuse it as secondary raw materials, and produce substitutes for derivatives of fossil hydrocarbons. These processes are aimed at applications in the production of biofuels, biofertilizers, biopolymers, biomaterials, and chemical precursors of biological origin, among others.


To be an internationally recognized institute in research and development of alternative energy and materials, as well as in the optimization of resource and waste management; to provide advice and consultancy to private and public companies throughout America.

Research areas

Three main research areas are followed currently at IDEMA, which are interrelated with each other from biomass or the use of residues of various kinds. The research areas are:

  1. Bioprocesses
  2. Biomaterials
  3. Thermo-chemical processes

1. Bioprocesses

The Bioprocesses research line investigates the production of bioethanol, biogas, organic acids and biols (organic fertilizer) from residual biomass rich in cellulose, hemicellulose, lignin and starch. This is achieved through biological processes such as biodigestion and fermentation using specialized micro-organs and controlling operating conditions to obtain products with applications in agriculture and food, as well as renewable energy sources.

Bioprocess Projects:

BioDO Project– USFQ

Description: The "Bio-digestion of organic waste" program focuses on the generation of biogas in an anaerobic bio-digester from organic waste from agriculture, livestock and food. Biogas is subsequently used for the generation of electrical and thermal energy. In addition, organic fertilizer with a high potential to replace chemical fertilizers is obtained as by-products.
Funding: Small Grants USFQ / Chancellor Grants USFQ.
Duration: January 2008 – undefined.


BioW2OH Project

Description:The Bio-wastes to alcohol (BioW2OH) project studies the production of alcohols (eg ethanol and methanol), from alternative products, such as residual biomass. These wastes are rich in cellulose, hemicellulose, lignin and starch, which will be rescued as raw materials. By using biomass residues as secondary raw material, added value is generated to the waste, in addition to taking advantage of organic carbon, which is part of the Earth's natural carbon cycle, so its contribution to greenhouse gases is minimal.
Funding: Poligrant 2017.
Duration: January 2012 – undefined


BioOrgAc Project

Description: The BioOrgAc project investigates the fermentation of residual biomass for the production of primary and secondary metabolites such as citric acid and lactic acid. These products are of interest for various industries such as food, pharmaceutical, biomedical, among others, for applications such as vitamins and food preservatives. The residual biomass is rich in cellulose, hemicellulose, lignin, starch, pectin, among others, which will be rescued as raw materials and synthesized through biochemical processes.

Funding: Poligrant 2017.
Duration: January 2016 – undefined       


2. Biomaterials

The Biomaterials research line investigates novel formulations of polymeric biomaterials based on agro-industrial waste and by-products such as lignocellulosic material, polysaccharides, and animal-derived wastes. With these biomaterials it will be possible to develop products with biomedical, biotechnological and food applications.


Biomaterials Projects:

 HydroPatch Project

Description: This project consists of the generation of hydrogels and biofunctional dressings through the use of chemically modified polysaccharides. These hydrogels are aimed at the controlled release of drugs and the engineering of different tissues such as skin, cartilage and bone, among others. Among the materials used are starches, pectins and chitosan, among others.

Funding: Poligrant 2018.
Duration: August 2016- Undefined.


µNPharm Project

Description: This project seeks the use of polysaccharides and fatty acids for the development of micro and nano-encapsulation systems for the controlled release of active agents. The elements to be encapsulated range from molecules, such as drugs and active compounds in cosmetics and biotechnological applications, to microorganisms that serve as biological control agents in agricultural biotechnology applications.

Funding: Poligrant 2017.
Duration: August 2016- Undefined.

3.Thermo-chemical processes

The Thermochemical Processes research line investigates thermal or catalytic cracking technologies, pyrolysis, gasification, and other thermal processes for the material and energy use of biomass, or hydrocarbon residues in order to obtain hydrocarbons from different chain lengths and a source of alternative energy such as synthesis gas, steam or directly heat.

CAPfuel – USFQ Project:

Description: The CAPfuel program focuses on the energy use of used plastics and oils by converting them into a liquid fuel through the CAPfuel-USFQ project (Conversion of Oils and Plastics into liquid fuels). The technologies to be studied are the following: cracking, pyrolysis and re-polymerization.
Funding: Chancellor Grants USFQ.
Duration: January 2008 - undefined.


Project SynFuel:

Description: The SynFuel program seeks to use the organic waste gasification process to obtain synthesis gas (CO / H2) and use it as a chemical precursor for the generation of hydrocarbons through the Fischer-Tropsch process, using light hydrocarbons as precursors. chemicals in gaseous or liquid form, and solids in biochar form for agriculture. This mechanism to generate hydrocarbons has a high potential to replace oil as a chemical raw material.
Funding: VLIR-UOS, Belgium.
Duration: May 2015 - December 2018.
