There are four applied research projects in which CETIM collaborates as a technology partner.
The leading partners of the DEGRADE, BIOCHARMB, BIOPOL and MEXICAL projects were exposing the specific objectives and the stage of each work.
Culleredo, November 29, 2019. The presentation day of the progress of four Conecta PEME projects in which CETIM is participating as a technology partner served, on the one hand, to make an outlook of the research carried out so far. On the other, it allowed all partners to have a forecast of the results that will be presented within a year to contribute to the advancement of the circular economy in Galicia. In all cases, the closure of investigations is set at the end of 2020.
During the event that CETIM hosted on Wednesday 27 at its facilities, the leading partners of the DEGRADE, BIOCHARMB, BIOPOL and MEXICAL projects were exposing the specific objectives and the stage of each work. Four projects are carried out in several phases until the end of 2020 with a total budget of 3.9 million euros, of which 56% (€ 2.2M) is financed through the Conecta PEME program of the Galician Innovation Agency (GAIN) and the remaining (€ 1.7M) corresponds to private financing provided by the 13 partners.
One of the main conclusions in the first phase of DEGRADE has been that during the synthesis of nanoclusters – photocatalysts applied to photoelectrocatalysis the process performance is increased by 44%. Copper nanocluster (Cu) have better characteristics for photocatalysis than the usual catalyst (TiO2) since in the degradation of methylene, simulating solar irradiation, after 17 hours, it is 60% when nanoclusters are used, compared to 16% degradation when TiO2 is used.
The general objective of DEGRADE is to develop a technology based on photoelectrocatalysis, through the combination of UV-LED lamps, to replace the current LED lamps of the treatment plants, with photocatalysts based on nanoclusters on a conductive material, and the generation of highly oxidizing radicals. The objective is to eliminate both emerging organic pollutants and pathogens from wastewater treatment plants. Its consortium consists of NANOGAP, LEDISSON and INTACTA Environmental Management (leader), with the technological support of CETIM and the University of Santiago de Compostela.
Through the BIOCHARMB project, a biomass utilization model will be developed based on the transformation of plant debris into biochar (a charcoal) through pyrolysis combustion. Apart from developing sustainable treatment systems with low construction and operation costs, BIOCHARM wants to open the way to diversify and increase the competitiveness of the Galician forestry sector. The consortium of companies formed by INTACTA (leader), GESTÁN, Valora Consultores and ENSO Innovation explained that after selecting the biochar of eucalyptus chips as the most suitable and modifying their physical and chemical properties to improve their adsorption capacity, it was designed and built the pilot plant for wastewater treatment that will now be put into operation.
In the case of biochar modification tests of the biochar for gas treatment, the pilot system design has also been carried out and, in detail, the engineering of the prototype to be validated in the Sobrado two CTR is being completed. Monxes
Circular economy in the Galician dairy sector
Thirdly, the objective of BIOPOL is to develop an eco-sustainable encapsulation of aromas and fragrances for the detergents and cosmetics sector by obtaining biopolymers (polyhydroxyalkanoates (PHAs), based on the use of by-products and waste streams generated in the industry milky.
In this state of the investigation, partners -ENSO Environmental Solutions, DairyLAC, CARINSA, SOELEC España and INDUTEC Ingenieros (leader)- have already designed and installed the pilot plant at the DairyLAC headquarters to obtain the biopolymer with which the four will be encapsulated Selected fragrances with satisfactory olfactory properties and microcides.
Specifically, the pilot plant consists of 60-liter reactors of useful volume, jacketed for temperature control, automation and process control system and temperature, pH and dissolved oxygen sensors, as well as real-time data visualization.
Finally, MEXICAL partners (INDUTEC Ingenieros, TRESIMA, VITALMAR and Galaytec (leader) have determined that the best methodology to optimize the shell of this mollusk and achieve “zero waste” is the enzymatic hydrolysis subjected to ultrafiltration. Next step, its suitability as poultry feed will be determined while the pilot mussel shell treatment plant with a capacity of 3 tons / hour at Vitalmar facilities will be launched.
