The Internet of Things (IoT) is revolutionizing how companies in every sector operate, manage and produce. We advance towards a more intelligent industry where all machinery is connected, and organizations can detect possible irregularities in real-time while measuring process performance. 

Battery-Less Sensor is funded by the Ministry for Industry, Commerce, and Tourism’s line of Innovative Business Groups. Projects like this focus on making progress towards the so-called connected industry. Battery-Less sensor is an IoT initiative developed by Valoriza Medioambiente, a Sacyr company, in collaboration with startup Alternative Energy Innovations (AEInnova) and coordinated by the Cluster de l’Energia Eficient de Catalunya (CEEC).

Battery-Less Sensor is a project that consists of using residual heat present in processes as a power source for new-generation wireless sensors with no need for batteries. This way, these devices measure temperature and vibration levels in industrial processes or monitor rotative machines to facilitate predictive maintenance, avoiding stopping production and creating early alerts of potential machine failures in industrial processes. The project encompasses power generation, obtaining, analyzing, and visualizing data: creating alarms to help prevent unforeseen events that might lead to an unexpected stoppage.

Currently, we monitor machines through solutions that work by wired sensors or require batteries. These methods demand a serious investment. Besides the economic cost, batteries present a massive environmental issue, as they are mostly produced with cobalt and lithium, which are scarce materials. Batteries also contain environmentally harmful heavy metals like mercury, lead, and cadmium. By the end of their life cycle, batteries are hazardous waste due to their high toxicity, inflammability, and reactivity levels. 

Solutions like “Battery-Less Sensor” are the alternative; devices powered by energy harvesting from industrial residual heat. Around 21% of residual heat power is wasted every year in the European industry. Likewise, research shows that we could retrieve around 336.9TWh of energy.

Battery-Less Sensor is in total alignment with the Sustainable Development Goals (SDG), and it contributes to improving the sector, sustainability, economy, and society in general. 
 
As of today, we have carried out pilot projects based on this solution to demonstrate the devices functioning in low-temperature conditions and isolated machines. However, these pilots face some technical challenges.

 

Battery-Less Sensor pilots

We executed these pilots in a few of our industrial plants: 
 
- Chiloeches out-of-use tires plant: installation of vibration and temperature monitoring system powered by thermal energy in a rasper grinder, which is vital for the functioning of the Chiloeches (Guadalajara) plant, as an unprogrammed stoppage would put production on hold. Monitoring is the outset of a predictive maintenance protocol. This case poses a significant challenge due to the temperature of the machinery (50 ºC or 122 ºF).
 
- Cirtec’s additive plant for asphalt mixtures: installation of vibration and temperature monitoring system in two reactors of the Cirtec plant. Temperatures in this plant are so high that go higher than 150 ºC (302 ºF), which requires the thermoelectric generator to adapt to highly variable temperature ranges. 

These pilots determine the system’s viability in other sector companies, proving that performance is enough to fulfill the machine’s requirements and develop a predictive maintenance plan. The following steps should integrate the data and alarm system into the current plant system to facilitate data analysis, making it more useful and making a system deployment to digitalize machines that we currently cannot monitor.  

Battery-Less Sensor aims to become a role model in the 4.0 industry as an alternative to current solutions (wired or battery powered), minimizing economic costs and eliminating environmental impact, in line with our commitment to the environment. 

Additionally, setting this project in motion reinforces our bet on promoting and backing collaboration with the innovation community to identify and boost new ideas that contribute to making a better, more sustainable world.

Construction for the future

The expansion of the Panama Canal is a colossal work from an economic standpoint as well. The Canal is a strategic route for international trade and at 6% of Panama’s GDP, is the country’s principal economic activity. With a total investment of almost 4,000 million euros, this project has yielded Panama up to 2,500 million euros per year and has generated 180 direct employment positions. 

Innovation at the service of engineering

We designed a unique kind of concrete in order to overcome the challenges that the area posed from the technical, orographic, geological, and climatic standpoints. We improved the formula to guarantee a lifecycle of at least 100 years. Chemical proof, this concrete can stand inner temperatures of up to 70ºC. We also worked on a pioneer earthquake protocol response model, designing a structure ready to respond to two kinds of seismic levels. 

An efficient and sustainable project

Right from the start, the expansion of the Canal has taken the environmental aspects into account. As the new set of locks is quicker to fill and empty, they consume 7% less water. The sluicegates have nine deposits that allow reusing water and save up to 60% of this precious resource. 

As for its atmospheric impact, we estimate that the third set of locks will help reduce more than 160 million tons of CO2 from the shipping sector in the next ten years. 

We also care about preserving the biodiversity of Gatun Lake, which the Canal traverses. Before beginning construction works, environmental specialists rescued and relocated all local fauna (such as turtles, caimans, sloths, and boa constrictors) to the adjacent San Lorenzo park. Furthermore, we reforested a surface area of 2,800 ha, planted close to 6 million trees, and carried out training, informative, and follow-up programs about the project with the local communities.

Rescue and relocation of local flora and fauna species

Right from the first clearing and dredging jobs, we established strict protocols to care for wild flora and fauna:
  • 4,500 rescued and relocated specimens 
  • 200 protected species 
  • 2800 ha of reforested surface
  • 5,8 million trees planted

Brief history of the Panama Canal

The Spanish were the first to promote the creation of a maritime route in Panama. In the 15th century, they opened the Camino de Cruces, connecting the Atlantic and Pacific coasts for the first time. In the 19th century, several expeditions took place in the isthmus, and the transoceanic railway was inaugurated, which was pivotal to the later construction of the Canal. In the early 20th century, the United States started looking into the Panama transoceanic route with a keen eye. A few days after the country obtained its independence, they won the concession for constructing the Canal from the French company Compagnie Universelle du Canal interocéanique de Panama. Construction works started in 1904 and ended in August 1914, going down in the history of engineering.

At the moment the biological processes of organic waste treatment (anaerobic digestion) that take place in waste treatment plants occur spontaneously, with minimal technological control and no biotechnological control. This generates multiple unknowns.

One of the main enigmas to be solved and on which the optimization and improvement of these processes is based on the control and knowledge of the populations of microorganisms involved in the process. In this sense, given their heterogeneity and spontaneity, as well as their relationship and dependence on operational factors, it is necessary to carry out research under the most controlled conditions as possible, so that the results and methodologies developed can allow extrapolating conclusions and future operating strategies.
 

Circular economy in urban services 

The main objective of this project is to design and develop a new anaerobic digester, on a small scale, to identify and analyze the populations of microorganisms involved, and to model the microbial processes that occur in each of the biomethanization stages.

This way, we achieve a biotechnological control that did not exist until now. All this, with the purpose of increasing the biogas production flow and its quality, reducing the amount of rejection destined to landfill and reducing its biological and chemical reactivity, making it more inert.

With this project, we promote the circular economy in urban services by having at the end the best use of waste for the reduction of waste that ends up in landfills.

One of the lines of action for reducing CO2 emissions is the decrease in the consumption of fossil fuels and the increase in the production of energy from renewable sources.
In this context, the recovery of residual heats, which are currently not being used, and the use of various types of renewable energies, which can be captured at medium temperature, such as solar thermal energy or medium enthalpy geothermal energy, would be important advantages both environmental and energy consumption reductions. In the same way, it would allow the increase of the use of renewable energies.

 

 

BOCALT

Is an R&D project that consists of the design and development of a new heat pump capable of using heat from sources at high temperatures (between 30ºC and 60ºC). This solution allows us to recover waste heat from industrial processes or renewable energy sources, capable of heating fluids to temperatures close to 80 ºC with high efficiency, incorporating a natural refrigerant that not only meets the requirements of the new F-Gas regulation for this type of equipment but scores highest on global atmospheric warming potential indices. All this, without damaging the ozone layer, and also using the latest generation inverter (modulating) compressors.
The potential for using this technology is enormous since it can be implemented in energy rehabilitation projects to replace boilers while maintaining radiators, in centralized sanitary hot water heating facilities without the need for a sanitization system, for heating process or industrial fluids. , to take advantage of the heat recovered from fluids or residual effluents, or to use springs or geothermal wells with low enthalpy (30 to 60 ºC), etc.

Wastewater from agricultural irrigation has a high nutrient content that seeps into aquifers and can cause problems of contamination of water bodies.
At Sacyr, we have launched a project for the reuse of agricultural drainage water, the Deseacrop project (Desalinated seawater for alternative and sustainable soilless crop production). 

Thanks to the development of this European Life project, we have demonstrated that desalinated water is not only be better when mixed with groundwater, but also increases crop yields and crop quality. In addition, as a novelty, we have treated the irrigation drainage water (approximately 30% of the initial irrigation) by reverse osmosis desalination so that it can be reused for irrigation. In addition, drainage treatment at the desalination plant is carried out 100% with photovoltaic solar energy.
