Few days ago, the European project LIFE DIOXDETECTOR was closed in CARTIF. The main objective was the application of a new analytical technique for the quantification of dioxins and furans, being this new technique, mainly, more sensitive and faster with respect to technical traditional.
Dioxins and furans are compounds that form part of a group of dangerous chemicals called Persistent Organic Pollutants (POPs).
When the word “dioxin” is heard, a certain alarm is created, and it is no wonder, because they are “worrying” compounds because of its high toxic potential as well as its persistence in organisms. The half-life of dioxins in an organism is between seven and ten years.
Big catastrophes such as, the serious accident in 1976 at a chemical factory in Seveso (Italy) or high concentrations of dioxins were found in poultry and eggs from Belgium in 1999 or market exit of tons of meat pork and pork products in late 2008 in Ireland, since amounts of dioxins were detected 200 times above the limit prescribed, among others…have been used to study the effects of long term dioxins and furans cause on health and the environment.
Dioxins and furans emission sources are mainly, solid waste incineration, industrial processes (paper mills, foundries, etc.) and road traffic, but also can also be generated naturally (forest fires, etc.).
And it is that although, the problem of dioxins and furans appear that it is so far, because it is possible that you do not live near an incinerator, due to the generalized presence of these compounds, all people have background exposure, which is not expected to affect human health. The effects on human health depend on the time of exposure to these pollutants.
These compounds can cause reproduction and development problems, affect the immune system, interfere with hormones, and in this way cause cancer.
In the environment, studies show that soil and vegetation near incinerators, can become contaminated by the release of dioxins and heavy metals at levels above normal background concentrations. The dioxin levels found in the soil and vegetation depend on the distance to the incinerator.
As cited above, solid waste incinerators are one of the main emissions sources of dioxins and furans. The European Directive for hazardous waste 2000/76, transposed into Spanish law in RD 653/2003, establishes as limit total emissions of dioxins and furans 0.1 ng/Nm3.
Undoubtedly, the most effective measures to prevent or reduce human exposure to these compounds are those taken at the root, i.e., in the own emission sources, with more stringent controls industrial processes in order to minimize the formation of dioxins and furans.
The analysis of these compounds is one of the most complicated in the world. The high toxicity of these compounds at very low concentrations, makes necessary the development of highly sensitive analytical techniques, as the technology proposed in the DIOXDETECTOR project, which is able to detect concentrations below the level of part per quadrillion (ppq).
It is clear that an improvement in air quality, it is quality of life. Just have to take a look at the latest news related to air quality: “Madrid exceeds the limits for nitrogen dioxide and active phase 2 of the protocol anti-pollution City” or “The poor air quality in Aviles forces to decree the pre-pollution alert”, among others, to realize the consequences that entails poor air quality in our daily lives.
It is not easy to find a definition for Smart Grid that summarizes every objective, topic and technology included under this concept. Searching and surfing the web, one can find long and detailed descriptions including many of the Smart Grids related topics, or other very brief and simple that are only focused in the points that the author of the definition is interested in. It is out of the scope of this post to deeply analyze those definitions, so assuming the risk of being too simple in our description; we can say that a Smart Grid should include at least these four topics:
– Distributed generation: improving grid management when a great number of small and medium power sources are present in the grid and when renewable sources have an increasing weight in the generation system. – Demand response: allowing final users, specially domestic users, to make decisions about changing their consumption habits thanks to the information that they could receive about energy price or because they can use local generation or storing systems to support their own demand. – ICT: for data acquisition and management in the different grid levels, from users to generation systems and including transformation centres. – Reliability: using data and information acquired from the grid to improve management strategies and also maintenance politics of every element in the grid, including predictive maintenance what guarantee an increase in the reliability of the whole grid.
If the Smart Grid becomes true in every level of the electric system, there will be a great number of benefits for the different actors in the grid, for example:
– To increase the capacity of using renewable power sources at user and global level – To reduce of the electricity bill for the users as they have enough information to shift their demand to the hours of the day when the electricity cost is cheaper. – To increase the capacity of the distribution system operator for generation and demand balancing – To ease the maintenance of the equipment installed in the grid extending their life and avoiding unexpected faults, with the logic economic and management benefits for the distribution system operator
To achieve these goals it is needed to develop or deploy the suitable technology for every challenge, knowing that many of these technologies are already available. These technologies must be focused mainly on three topics:
– Power sources: including renewable power sources and batteries of different scale and power rates. These will allow a better use of the available energy in every site and for every user. – Equipment and devices for grid operation: including smart meters, remote operated devices and drives, smart appliances… To help accessing the grid data and information and also for a quick and remote operation of the devices that will deploy the management decisions in the grid. – Decision support systems, to help in the generation and demand balancing taking into account the different objectives that must be satisfied in the grid.
But it would be a big mistake to think that a grid will become smart when all these technologies are available or that these technologies will introduce the intelligence in the grid automatically. As an example we can notice that in Spain , the company Iberdrola has installed a smart meter to a 76% of its clients but it is difficult to find someone that has changed his electricity consumption habits thanks to the information that they can obtain from that devices. Even though when this could imply to reduce the cost of their monthly bill.
Without any doubt, we will deploy really smart grids only when everyone involved in the generation, demand, design, tools deployment or grid management could be part of a smart network of people working together for the same goal.
This imply not only to be smart for developing the best tools and technologies needed in every application, but also to be smart in selecting the final goals that we want to obtain. In this sense we can call “smart grid” that network in which everyone share the same sustainability objectives, environment care and optimal exploitation of available renewable power resources. Of course that economic profit is also needed to mobilize the required investment and involve many of the actors, but if this is the only goal in the short-term probably will not able to build a really smart grid. In our opinion, a smart grid will be the one in which:
– the users understand that participating in demand response strategies not only reduce their electricity bill, but also will contribute to build a system where renewable resources could be better exploited. In this way they could offer their flexibility in energy demand even though when their economic benefit could not be high, but they will be contributing to the environmental care. – the distribution system operator assume that their investment in the grid besides the economic profit should also search for a social and environmental benefit even though when the economic one could be limited. – the government facilitate the use of those technologies that increase the energy independence of the domestic users and that allow to take advantage of all the available renewable resources.
To sum up, a smart grid will be the one in which the common benefit of the society in the mid and long term is the main goal of every decision, either in the strategic ones made by humans or in the automatic ones made by the smart devices during the grid management. Because the intelligence is not only in the developed knowledge but mainly in the way we use it.
There is no doubt that the snack food market is one of the strongest in the food industry, as is evidenced by its increasing market value. The snack category of food used to meaning snack chips, nuts and other traditional snacks (extruded snacks, popcorn, nachos etc.). However, the snack category is currently expanding to a large number of products that often has nothing to do with what we knew as snacks.
Historically, the snacks were something that we consumed around the daily main meals and that made us feel guilty about eating too much calories. We used to tell to our children “don´t fill up on snacks” before lunch or dinner. However, consumption of snacks has become increasingly common and is no longer between meals, is the food!.
Certainly, the culture of food is in constant motion (and who said for the better?) adapting to new lifestyles (cooking less, spend more time away from home) and in this new attitude there is room enough for more varieties of products that are easy to eat, with no-needed or very little preparation needed and a size easy to take away.According to Nielsen, the nowadays picture in Spain is that 45% of consumers regularly eat a snack as an alternative to one or more meals daily. Out of this value, 52 % do it for breakfast, 43 % on luch time and 40 % at dinner moment.
But consumes become more aware of nutritional values and claim for snacks to be healthy (or make us feel less guilty of eating out of the three-meals patron …) and to provide some health benefit. This is driving the food industry to spread the wings of innovation and create all kind of products rich in nutrients (proteins, vitamins, minerals, etc), fresh (or minimally processed, but packaged and ready to use), products high-density, low-glycemic index, low sugar, salt and fat among others. Here is a small sample of what is already in the market and what is coming soon:
Cereals, pulses, vegetables and fruits. The healthy snack category
The perception of the snack as something unhealthy and loaded with calories fades with launched products to cover this category. We found a wide variety of dehydrated fruits and vegetables (whether or not coated and with more or less sugar content), cereals of all shapes and colors, but mostly whole grains, either alone or mixed with goji berries, berries or dry fruits. Very present, the so-called “ancient grains” (chia, sorghum, quinoa, millet ..) cooked and ready to eat in bars or expanded products. Probiotics have migrated and are no longer in yogurt .
Now they are provided by fermented vegetable, or cereals, proteins, rice and chia with probiotic cultures. There is also a great tendency to germination process: cereal flour and sprouted legumes that are attributed interesting nutritional properties and are considered more easily digestible. And undoubtedly coming hard, combinations of cereals and vegetables or fruits and vegetables that add flavor, color and above all … nutrients, especially vitamins A, C E and D.
Dehydrated fruit and vegetable snacks
Pulses (white bean and pinto beans and lentils) and germinated cereals snacks
Fruit smoothies
Proteins: the meat snacks
Considering meat and fish as a protein source, different types of snacks and even innovation formats for consumption processed meat products are arising. Some examples are shavings of ham or corned beef, the so-called jerkies (dehydrated or marinated meat), seasoned with all kinds of spices and aromas.
Seasoned jerkies
And coming to snack market: meat sticks or bars. High protein content, veal, lamb, pork, bison… or insects.
Beef and vegetable and insect flour bars
Beef, chicken, pig, turkey, salmon or…bison bars
One size cured meat product
The dairy snack market
The dairy snack development is mainly focused on children. Thus, we find a wide variety of packaging formats such pouch or bag to take away. Healthy solutions for children through the development of dairy sticks (e.g. with the calcium content equivalent to a glass of milk, rich in protein and low in calories) but above all, innovation in the packaging presentation: single dose or ready for consumption, mainly at school break or at the playground time.
Small formats for cheese
It is very clear that the snack development offers great opportunities and there are many companies who see in the snackificationan opportunity to develop a palatable, healthy and ready to eat between meals or as a meal. Of course, according to the consumer criteria of what they percive as healthy, sustainable and what they are willing to pay for it. Of course, a reflection exercise must be done by the food industry to combine all these keys and consider that innovation happens largely by new or unusually ingredients and new production processes or technologies.
Let me remind you that Europe features the most diverse, rich and numerous cultural heritage around the world. 609 million tourists visited the “old continent” by 2015 (29 million in 2014) according to the World Tourism Organization, and, although it is somewhat pretentious, it is suggested that 37% of these tourists are cultural tourists, a figure that grows by 15% each year. This “curious specie” wanders around the cities getting the urgent need to visit the built heritage and being actively involved in cultural events.
I agree on speaking about cultural heritage as a touristic resource is disappointing when heritage is properly identified as integrator item and a completely intangible social identifier, but also certainly is an economic resource and just making cash its sustainability is ensured. This is the way to fix and create thousands of jobs, which in turn reinforce the character of social backbone that heritage is by itself, even allowing to improve the citizens’ quality of life.
Because of this the public sector comes boosting the creation of more and more cultural attractions with the built heritage as backdrop. Cultural tourism is perceived as the main source for funding heritage preservation: tourists generate the resources needed for maintenance and restoration. Let’s see if this is really so in the coming years, since the Richards report, ensures there is a much higher offer than real demand right now.
Making sure the protection and the preservation of our built heritage is, today, more urgent than ever. Not only as “prey” of cultural tourism, and not only as a brand of territory (including citizens), but because of their vulnerability to pollution, climate change and socio-economic pressures. We all get sick from time to time and we know it is always better to prevent than cure. The same happens to the built heritage: it is as much desirable as important to have automated systems that continuously tell us how the built heritage is, preventing “ills” just before they are such as expensive as irreparable. It is somewhat comparable to doctor’s auscultation, but what do we need listening to? In the technical jargon we say “monitoring” and many types of sensors are used to, but three aspects are mainly registered:
The temperature and relative humidity. Both are always linked (in fact they are inverse). Any kind of heritage building has greater or lesser water content in the air at a given temperature, having a decisive influence on the physical-chemical stability of the materials they are made of. Inadequate conditions of temperature and humidity produce deformation and rupture; rust and corrosion; as well as bio-deterioration (emergence of organisms).
Natural and artificial lighting. the Sun, or electric sources are electromagnetic radiation mainly covering the ultraviolet (UV), visible (VIS) and infrared (IR) ranges. Together they cause photo-degradation (discoloration) and temperature increases, especially in the case of organic materials (paintings, textiles, books and documents).
Pollutants. The air composition and quality are altered by compounds that mostly come from the use of fossil fuels (road traffic, heating of buildings and industrial activities). These compounds are able to make chemical reactions that affect the materials causing corrosion; spots and coatings; and also bio-deterioration.
These parameters will be particularly broken in subsequent posts.
In any case, the role of technological centres as CARTIF is decisive to take step forward in the technical developments required so that monitoring can be done affordably and fully compatible with the aesthetics and functionality of the building. Relevant international projects on this regard where CARTIF is playing a major role are:
After Italy and recently China, Spain is the country that holds the largest number of human heritage sites. We are also a first order world tourist destination, with a yearly increasing cultural component. Playing at home, Castilla y León accounts for 60% of the Spanish heritage… Do we take the fingers out?
I had planned to continue talking about Green Manufacturing initiatives, but I have decided to write a new post with a different but complementary approach to sustainable manufacturing.
Before the Flood is a 2016 documentary film about climate change firstly screened on 30th October 2016 on the National Geographic Channel. Directed by Fisher Stevens and starring Leonardo DiCaprio. The film was produced by a collaboration between Stevens, Leonardo DiCaprio, James Packer, Brett Ratner, Trevor Davidoski, and Jennifer Davisson Killoran. Martin Scorsese is an executive producer.
The film shows DiCaprio visiting various regions of the globe during 3 years exploring the impact of man-made global warming. Along with Leonardo DiCaprio, the documentary includes interviews with Barack Obama, Pope Francis, Sunita Narain, Elon Musk, and Johan Rockström. I strongly encourage everybody to watch this film. It is widely available and free of charge on various platforms like the National Geographic Channel in Youtube
I have been fortunate to work on the demonstrative REEMAIN project during the last three years. In this project, among other multiple activities, three demo factories (biscuits, iron foundry and denim fabrics) are voluntarily –and supported by European funds- taking several initiatives in order to increase their efficiency in terms of energy and material resources consumption.
Even in subsidised scenarios like REEMAIN, it is not easy to achieve the required modifications in the manufacturing processes and installations in order to merely reduce the corresponding environmental impact, especially if the modifications affect the expected profits. Therefore, although some proposed measures should not affect the factory profitability, they are still perceived by the Managers as unnecessary risk or uncertainty elements.
Why should any company turn its production and operative systems upside down to fight against climate change? What happens with those companies whose products or production processes are inherently polluting?
Simply encouraging companies to include among their main objectives the fight against climate change is a good idea, or at least is better than doing nothing, but it is clearly not enough. The process will not be fast enough. The change must be externally boosted, and it is our responsibility as citizens-voters-consumers to assure it. One possible booster is the politician power through the adoption of new more restrictive legislation like the banning of coal use in the European cities. The other booster might be the consumers awareness and consequent rejection of those products and services associated with a high environmental impact. For example, the campaigns against the use of palm oil.
This film of DiCaprio is naturally more oriented towards the American public. Hence, it takes some time to explain the USA politician system and the economic relationships established between politicians and big hydrocarbons companies. Because of it, currently in the 2016 America Congress and Senate there is an important percentage of representatives that directly deny the climate change. In Europe, our politic representatives fortunately, no longer have doubts about the climate change. However, it seems like if the possible negative effects over the economy were slowing the development of new regulations that restrict or directly ban the most polluting products and processes. A practical example of this issue is the EC authorities management of the “Dieselgate” scandal.
The movie ends –this is not a spoiler, since the important idea of this film is spread through the whole movie- with a clear message: It is up to all of us to stop the climate change. It can be achieved using two tools: our consumer habits and our vote.
Consume differently. Reflecting on what we buy, what we eat and how we get our power, might make a first step.
Vote for leaders who will fight climate change, will make the second step. Leaders that will end fossil fuel subsidies and exploitation, invest in renewables and support a price on carbon.
I absolutely agree with both proposals. However, I would add that in addition to consumers and voters we are also citizens, hence, we must try to communicate and convince the rest of the citizens about the importance of stopping the climate change. This post is my first grain of sand.
I tell you a real situation: Some years ago, I was chatting with a friend, when she looked at me very serious and said: I am not be able to lose weight! My doctor says that vegetables fattens me and the worst thing is that I love it! In that moment, those words seemed so absurd that I stayed quiet. Today, almost 20 years later, I have understood that my friend (a clear visionary) was speaking about genomic nutrition o personalized nutrition.
As we know, in the studies of dietary intervention, the results are the average value of all individual who have participated in the study. But, what would we find out if the results would be analyzed individually? In some people, a change in dietwouldn´t feel any effect (hypo-responders), others would feel a medium effect (normo-responders) and others would feel an effect greater than expected (hyper-responders).
During the last decades, we have passed from believing that diet produces the same effect in all individuals to accept that changes in diet are partly caused by the inter-individual differences in the human genome.
And that is precisely what we have lived in projects about “health food” developed in CARTIF. If we look back, we have more than 20 years designing functional foods and even collaborating in intervention studies in humans with the objective of verifying its effectiveness.
The project CENIT HIGEA (2007-2010) was undoubtedly the most important in the design of food with beneficial effects on health. In this project we feel ourselves as Dr. Brand on “interstellar: we were missing variables to solve optimally our trials of intervention.” We had not contemplated that the response to food varies depending on the specific characteristics of each person!
In fact, in a trial of intervention realized in HIGEA, we got that the consumption of a bar enriched in Omega-3 only produced an improvement in the lipid profile and the inflammatory pattern in men but not in women who participated in the study.
With these antecedents, in the year 2014 we began to work in the Project PRIMICIA. As its name suggests, for the first time, we get ingredients and healthy food (cookies, juices, jams, and pasta) bearing in mind the genetic profile of the population. It is necessary to mention that although the advances in the knowledge and technologies developed about of the human genome have been spectacular during the last years, the nutritional genomic is still a recent discipline and there is some confusion.
The project PRIMICIA is just the beginning in the industrial development of effective foodto improve the health of people in a personalized way. I propose complete the famous phrase “You are what you eat” saying: “You are what you eat because this determines which genes are expressed” and as I also have the gene “mother”, I would add: “so be careful!”
