BiALAC ​​project, presentation of results

Cartel BiALAC The main objective of the project is to develop a biomaterial based on biodegradable polymers , polyhydroxyalkanoates (PHA), at a reduced cost through the use of raw materials of low value and difficult to recover for project participants, such as permeate from the ultrafiltration process in the dairy industry and sludge from urban treatment plants. The project will simultaneously reduce the production costs of biopolymers , enhance permeate and sewage sludge, and produce new 100% biodegradable food packaging formulations .

During the first year of development of the project, the initial tasks of preparing the facilities to house the biopolymer production pilot plant, plant design and characterization of the permeate and sludge have been carried out. treatment plant, both from the physical-chemical point of view and with respect to its anaerobic digestion potential and the limiting factors of the production of volatile fatty acids, polymer precursors.

During the second year, the characterization studies of the permeate and sludge continued, the design of the pilot plant for the production of biopolymer was completed and installed in the factory of Quescrem , then proceeding with its start-up and adjustment of the process parameters.

During the third and last year of the project, the characterization studies of the permeate as food for the pilot plant continue and with the operation of the same for the production of volatile fatty acids and biopolymer. Controls of the operating process, sampling, analysis of the basic operating parameters of the reactors, etc. are carried out on a daily basis, keeping track of the entire process and operating conditions. Similarly, laboratory-scale co-digestion studies continue to better adjust the operating process of the plant. As it stabilizes and biopolymer production is achieved, extraction and purification processes are carried out. The characterization of the biopolymer then continues, evaluating its thermal and rheological properties, and the necessary formulation is made for the development of a biocomposite suitable for its application. Finally, the validation of the containers obtained from it is carried out.

This project has had a duration of 2 years and 4 months, beginning in May 2018 and ending in September 2020. Several entities have participated in the development of the project (Emalcsa , Ecoplas , Abakal Ingenieros and Innolact , with the collaboration of research groups of the Universidad da Coruña ), with a budget total of € 665,776.86.

This project has been subsidized by the Galician Innovation Agency, supported by the Ministry of Economy, Entrepreneurship and Industry, and co-financed by the ERDF (European Regional Development Fund) of the European Union.

Europe, leader in the hydrogen race

UE flag Europe has a clear objective, to achieve the climate goals set in the Paris agreement, the path, to reduce greenhouse gases until their elimination in 2050.

Last Wednesday it was known that the European Union has taken the lead in the race to use hydrogen as a non-polluting source of energy. It is expected that in the next decade, 45% of the investments in this field will be made in the territory of the continent.
Of the 228 hydrogen-related projects announced globally, 126, more than half, will be carried out in European Union territories. "Stable political commitment allows the industry to have the confidence to act," said the director of the Hydrogen Council.
The 300 billion dollars budgeted for the development of hydrogen, barely represent 1.4% of total investments in the energy sector, but it is estimated that the percentage will grow in the coming years. In Spain, for example, 38 hydropower plants are planned to start up before 2025.

BiALAC Proyect, circular economy.

Logo Bialac Abakal, in conjunction with Emalcsa– the municipal water company of La Coruña – and the companies Innolact and Ecoplas with the collaboration of the A Coruña University are working on the development of a new biopolymer from whey from industries in the area and urban sludge from Galician treatment plants, in the framework of the BiALAC project.

In 2019, the biochemical tests and the project of the different phases of the pilot plant were completed to achieve the transformation of the fatty acids of these by-products into biodegradable bioplastics. Once this laboratory phase was completed, the construction of a pilot plant that incorporates this process was completed in 2019 in order to increase the production of these bioplastics and assess their availability on an industrial scale.

The different possible configurations of the pilot plants are currently being tested and conclusions are being drawn for the real-scale implementation of an efficient bio-plastic production plant. The bio-polymers obtained have application as plastic materials from renewable and sustainable sources that in a short time will be of mandatory use in the food industry.

In conclusion, the BiALAC project will allow industries to give added value to the by-products of their production and to reuse waste from treatment plants. With this system, food companies will be able to be at the forefront in terms of circular economy policy in relation to by-products and raw materials in their packaging.

App for calculating Beams on Android

Foto del punto de retorno del caz Our colleague Luis Nieto, has developed in ABAKAL a free application for calculating beams on Android devices.

This program facilitates the calculation of bending, shear and deflection moments in a beam of constant section in a very simple way.
To do this we will have to indicate the length of our beam and add its supports. Once this is done, we can add the moments and loads, both punctual and distributed, to which the beam is subjected. The distributed loads can be uniform, trapezoidal or triangular, depending on the value that we indicate at the ends.
Once our beam is configured, the application will carry out the necessary calculations and prepare a report with the values of moments, shear and deflection. We can export this report in csv format to be able to consult it in a spreadsheet on our computer. In the application we can quickly consult the specific values of each magnitude simply by moving your finger through the diagrams.

Technical assistance fot the concession of water intake, Henares river.

watercourse return point photo In the 16th century, Cardinal Cisneros bought the Borgoñón mill to donate it to the Colegio Mayor de San Ildefonso. This mill is powered by a water diversion tank through which almost 3,000 L/s have circulated. However, after years of disuse, the mill and the watercourse need to carry out works to integrate them into the urban landscape of the city.

Last may, the Council of Alcalá de Henares formalized a contract that seeks to improve the river environment, which is in tune with the large recreational area of the College Island composed of urban gardens of the European Horizon 2020 project, sports courts, parks and walks.

The works in the mill watercourse will consist of cleaning and recovering the watercourse and putting it into service, respecting at all times the riverside vegetation, the gallery forest and the fauna that has been established throughout these years, allowing the citizens of Alcalá de Henares enjoy this space.

From Abakal we hope that this objective is fulfilled and that the people of Alcalá take advantage of all the possibilities that the College Island, the watercourse of the Mill and the Henares river can offer them.
