José Vicente López Álvarez, Universidad Politecnica de Madrid - Lecture Ecoembes
A combination of factors is driving the use of biodegradable plastics. Among them are:
- The high price of petroleum-based resins.
- The increasing consumer awareness about the need to protect the environment.
- Technological maturity reached during the generation of high performance products with these resins.
This explains why in the past five years packaging suppliers have launched biodegradable plastic containers, made from various plants, especially corn, confident that demand will respond positively to their offers. Due to rising prices since 2005 had conventional resins, between 30 and 80%, many companies are inclined to seek alternatives. Some biodegradable plastics have developed a level of maturity that allows them to be competitive, the price gap that separated them from the common resins has decreased considerably, and commodities such as sugar cane and starch are currently cheaper than oil. The productivity and competitiveness tend to increase long-term perspective, and it was evident early and massive concrete applications for these polymers.
Some companies predict that the market for bioplastics in Europe will grow at a rate of 20% per year
Biodegradable plastics can be produced from renewable resources of animal or plant, or fossil resources. The most common materials are PLA, polylactic acid, and PHA, poly-hydroxy-alcanoatos. It is the chemical structure that makes a biodegradable polymer, which unlike a conventional polymer and allows it to be destroyed by microorganisms such as fungi and bacteria in biologically active environments. Although figures are not official, it is estimated that the current market for biopolymers is around 300,000 tonnes per year (base 2007), in which the European consumption is around 50,000 tonnes. Maintaining the continuous growth that has occurred so far, the overall capacity required for production of biodegradable polymers reached a million tons around 2010. In this perspective, Ecoembes considered necessary to determine the impact of so-called bioplastics in the management chain of recovery and recycling of conventional plastics. The Environment Ecoembes Chair of the Polytechnic University of Madrid is developing a project to meet this need. The project includes several aspects: criteria for differentiation between bioplastics and biodegradable plastics, quantification of the production and use of this type of plastic, compliance with established standards of biodegradability in the European Union, impacts on current management processes: collection, plant selection (impact on processing lines) and recycling (impacts on processes and mixtures of raw materials).

Some companies predict that the market for bioplastics in Europe will grow at a rate of 20% annually. Experts, including the Biodegradable Polymers Association and Affinity Groups (IBAW), estimate that with the existing quality and prices is possible to have a growth potential for cornering almost 10% of this market of plastics, which arrives in Europe currently about 45 million tonnes per year.
Currently, the market for biopolymers is developing but still can not compete with traditional plastics
Currently the market for biopolymers is developing but still can not compete with traditional plastics. In the European Union some countries have in their shops fruit and vegetables packed in BPL, but in the case of Spain, the market for BPL in containers is limited to any campaign in any mall.
The market for BPL
The projections are made worldwide for 2010, expects growth of installed global capacity for production of biodegradable materials is 75% compared to the present. Although at present the absolute values do not reach even 1% of the total demand for plastic resins in the world, the growth of biodegradable resins is very high.
A combination of factors is driving the growth and acceptance of biodegradable resins, which are:
- The rising price and high oil-derived resins.
- The consumer awareness on the need to protect the environment, purchase produce 'greener'.
- Technological maturity already achieved in the basic generation of products with these resins.
- Government laws are brewing in several countries, particularly in Europe, encouraging the use of these biodegradable products.
- The exclusion of waste management systems such as landfills and the poor image of energy recovery as a final solution.
Against this background Ecoembes considered necessary to determine the impact of so-called bioplastics in the management chain of recovery and recycling of conventional plastics, and in particular in the management of packaging. The Chair Ecoembes of environment of the Polytechnic University of Madrid is developing a project to meet this need.

It is defined as 'compostable packaging' to one that is biodegradable, producing mainly carbon dioxide, water and humus at a rate similar to that of simple organic materials (eg cellulose) and leaves no toxic or visible residue.
Bioplastic project
The project defined and specific criteria for differentiation between BPL and biodegradable plastics and, above all, the scope of the certificate of composted called these containers.
It is defined as 'compostable packaging' to one that is biodegradable, producing mainly carbon dioxide, water and humus at a rate similar to that of simple organic materials (eg cellulose) and leaves no toxic or visible residue. There is legislation in the European Union, as the Standard EN 13432 in force since January 2005, among others, which could certify compostable plastics and containers made from them, so that consumers can easily distinguish them. Certification and labeling of bioplastics and biodegradable / compostable, would deal with these post-consumer materials along with the organic waste (food scraps, pruning, papers, etc..) Municipal solid waste composting plants.
Requirements for obtaining a plastic container labeled 'compostable':
- Biodegradability (90% before six months).
- Disintegrated: the fragmentation and loss of visibility of the residue in the final compost (absence of visual contamination). This is measured with a composting test (EN 14045), in which the material must be broken before 3 months, with a size less than 2 mm and reach 90% of the initial mass.
- No negative effects on the composting process itself.
- Low levels of heavy metals (below the predefined maximum values), and the absence of negative effects on the quality of the compost (eg reduction of agronomic value and presence of eco-toxic effects on plant growth).
- Other physical and chemical parameters that should not be different from the control compost after the degradation: pH, salinity, volatile solids, N, P, Mg and K.
Therefore, under this hypothesis, the reason for the packaging of BPL is that the final residue will be managed along with organic matter for composting.
Issues that arise with the use of BIOENV
The market trend is to replace the packaging of malls synthetic plastic packaging for fruit and packaged foods manufactured by other biopolymers. This would avoid, manufacturers claim that many of the containers end up in landfills and composting could be directly with organic matter.
Many supermarket chains and stores in Europe are encouraging the use of these biodegradable packaging to meet the interest of consumers to reduce use of fossil fuels and prevent climate change. Companies know that biodegradable packaging are unpopular among the public with an environmental and want to show their support for sustainable development adopted in their marketing plans.
Conclusions
Within the group of degradable plastic containers, the BPL is presented as an opportunity in all environmental strategies demanded by society. However, technical limitations when it comes to sustainably manage their waste, are still high. The evidence is translated into:
- The market for BPL will be a replacement market, primarily by a shortage of raw materials and competition with other sectors such as bioenergetics and feeding.
- Achieving total biodegradability and no toxicity, is currently investigating. Some biopolymers are not achieved the desired levels.
- Would be needed to develop an infrastructure to collect and process biodegradable polymers as an available option for waste disposal.
- Need for international regulatory or grade to distinguish between biodegradable plastics recyclable plastics.
- The creation of 'eco', based on the life cycle impact of a BIOENV (including raw materials, energy consumption, emissions from manufacture and disposal of waste).
- Education and awareness of biopolymers. Consumers will have to learn that the biopolymers must be separated with organic waste (if available separation) or recovered (where appropriate) and precise technology develops.

The new regulations of the EU GMP
On 1 August 2008, the law No (EG) 2023/2006 "On Good Manufacturing Practice (GMP: good manufacturing practices, for its acronym in English) came into force in the European Union. It is part of the European regulatory framework that governs the contact 1935/2004/EC of articles of daily use with food. The purpose of these laws and regulations is to eliminate, at every link of the supply chain, impurities in foods that may endanger the health of consumers. According to GMP standards, there must be a system of improved processes and quality assurance for plastics that come into contact with food.
photo
Among the traditional fields of application include Luran S appliances like coffee makers, juicers, microwave dishes and toothbrushes.
For many years, BASF has produced resins that are used in applications that come in contact with food at a level higher security requirement. However, the new law requires the manufacturer of resins also select and approve a special raw materials and to implement comprehensive measures in terms of documentation and quality assurance in the past. BASF offers its customers the written documentation that confirms compliance with relevant EU legislation.
Toothbrush and juicers
The formulas and manufacturing processes of the three new degrees of Luran S were modified to match the performance of the new legal requirements. Luran S K FC 777 is a material of great fluidity and hardness that is used as base material for a wide range of applications and Luran S 757 G FC offers rigidity and high resistance. Among the traditional fields of application include Luran S appliances like coffee makers, juicers, microwave dishes and toothbrushes. The most important product properties for these applications are high thermal stability, good chemical resistance and good resistance to aging and yellowing.

Organic coating
Adhesion (property of atoms or molecules of a substance consisting of atoms or molecules attract other substance with which they do not have a chemical bonding, or state in which two bodies are held together by interfacial forces which may be valence forces or action and crossed both) plays an important role, most importantly, in surface coatings, and particularly in the screen printing inks, since it is the foundation of all screen coating on the fact which is part of the support, forming a single body, united (Glass, PVC, PP, PE, PC, PE, PET, PMMA, aluminum, steel, wood, etc) by the affinity of adhesion, or by the solvation of the medium due solvents in the formulation.
To date, most of the time, the ink formulations for PVC and others have been and are made with some solvents (Isophorone Cliclohexanona, vynil pyrrolidone 2 etc) so that the ink provides a good grip on the substrate at the expense of These thinner, an ink made with vinyl vinyl resins never join on PVC or PMMA, with the help of the aforementioned solvents.
The vinyl pyrrolidone 2 years ago that this obsolete because it is carcinogenic (toxic Pictogram T) Isophorone is irritating to the eyes, respiratory tract from the skin so. (Pictogram for Xi irritant), the cicloexanona damages (Pictogram for harmful Xn) this solvent is the least harmful to the health of those who act as promoters of adhesion but often by their volatility is not enough bonding agent on rigid PVC, methyl, etc..
Not to mention oil, heavily polluting the environment.
To get a good grip on any substrate either plastic, wood, steel or aluminum, the bond must provide products that meet the above definition, making vehicles (resins and additives) with the properties mentioned in attracting atoms print media, which maintains a force of attraction and cohesion to ensure a total grip over a very long time, in addition to providing resistance for a coating, such as chemical resistance and physical demands of us the consumer, such as resistance to alcohols, alkalis, acids, alkalis, weathering, salt spray etc.
This usually is achieved with inks and paints of two components, which usually has very good adhesion a very large number of substrates, in addition to a very high solids content, thus avoiding having to resort to harmful products, irritating and harmful to health . The ability of isocyanates to be combined with some elements on the surface of the substrate to be printed is amazing at times, mostly on plastics such as PVC, methacrylate, polycarbonate, polystyrene, (do not forget that the inks made with alcohol, not harmful to health, not adhere on polystyrene) and other types of plastic, these products appropriately respect the environment. Sometimes the grip achieved by using temperatures higher than those of the environment, ie curing coatings
from 80 to 200 º C, in inks and coatings of two components, for surfaces such as stainless steel, brass, aluminum, polished, painted surfaces are difficult to grip in the latter case the drying temperature should be slightly lower than Tg (glass transition temperature ) of the painting, ie the point at which the paint film softens slightly with temperature and then printing ink is the kind that is attached, in addition to improving adhesion, resistance of printed films.
The poliaminoamidas and polyamides, which are the tubs of Epoxy hardeners, have very good adhesion on the following substrates, Glass Aluminum, Copper, Brass, Ceramics, Silver and Gold, Formica, painted surfaces etc. but since these are more harmful to health than isocyanates, in contrast, if the inks are formulated properly respect the environment, but not aspirated
the water.
New Generation inks to water or water for PVC and other if they are made without coalescing (Thinners), they are respectful of the environment and the health of the user,
The resins containing paints or inks in aqueous dispersions of resins are suspended in water, or colloidal state, ie are finely suspended
in the liquid resin particles are solid (the same that are used to produce solvent inks) to join a continuous film formed by means of heat or by joining with one another, also without heat through the solvation of resin using the solvent as appropriate in each case, according to the type of polymer, if type acrylic, vinyl, polyurethane, etc. These dispersions have been removed by evaporation when 25% of the water contained in them is when they start coalecer ie soldiers to join with each other and the particle as previously mentioned, but if we work with extenders to produce this phenomenon and not care for the environment, whereas if we put an ink dispersion, with a TMFF (minimum temperature of film formation), less than 5 º C, not to work with any thinner and this will result in a product with a great respect for the environment, achieving a perfect grip.
One of the drawbacks with some inks are water-drying is slower when applied on a support nonabsorbent, however today it is being formulated aqueous inks with extraordinary properties of rapid expulsion of water from reaching film printed Sometimes the speed of conventional PVC.
Another disadvantage of these dyes when they contain substantial quantities of diluents is that the user to remove the waste ink and wash these screens can not eliminate the drainage of its industry, it must treat them as normal until the inks today, if they do not contain diluents then depend on the ecotoxicity of the components of the ink, for example according to the type of fungicide, which are not biodegradable, but in most cases are usually not harmful because any product that has no solubility in water of rivers or seas, apparently does not harm our wildlife.
The water-soluble inks and coatings can make all kinds of paintings echo long since done, Polyurethane, Epoxy, Acrylic, Vinyl, Gliceroftalicas, Etc. One-two components.
This thinner and achieve optimal product for the environment in general.
Long ago that we talking about the water-based paints and inks, and all ink manufacturers have developed and some have even sold, but
industry tends to reject screen because I think it is a novelty for the time being unprofitable, and that this must be changed throughout the game screens
install other methods of drying and then an ink that will never be with water as the drying ink for vinyl to a diluent, for vending machines with drying tunnel which is now built, tunnels of up to 5 meters with cooling zone, where the actual drying of the printed surface is at about 45 to 60 seconds. But in return we must work with water, we do not have to worry about exit gases, not by burning them in their outputs as shown with the EU and the municipalities concerned.
The UV-cured inks are respectful of the air, but not highly recommended at workshop, or to flora, aquatic fauna, or vegetation.

United Kingdom provides 100,000 of influenza A day before the end of August
The Minister, Andy Burnham, said in the House of Commons that will change their strategy to cope with the virus:
"We have always known that it would be difficult to contain the virus indefinitely and that at some point we should move from the stage of disease prevention, the treatment stage."
Since the government denies that the situation is out of control and ensure that preparations for obtaining a vaccine are at an advanced stage.
United Kingdom is the European country most affected by influenza A nearly 7,500 people infected, of whom three have died from the disease.
Spain instructs two laboratories 18 million vaccines against influenza A

Hoffmann Mineral: Las aplicaciones de los Aktisiles (cargas con recubrimientos)
Aktisil
The Aktisil grades, i.e. activated Sillitins, are produced by modifying the surface of Neuburg Siliceous Earth with chemicals, specifically with selected silanes. Several different grades have been developed in order to always ensure optimum coupling between filler and polymer.
In comparison with untreated Neuburg Siliceous Earth, the Aktisil grades, through improved wetting by the polymer, offer manifold benefits in different fields of application:
- Disperse more readily
- Improved rheological properties
- Improved coating resistance
- Increased anti-corrosion properties
| Product | Basis | Treated with | | | | | | | | | |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Aktisil VM 56 | Sillitin Z 86 | Vinyl silane | | | | | | | | | |
| Aktisil MAM | Aktisil V 88 | Methacrylic silane | | | | | | | | | |
| Aktisil MAM-R | Sillitin V 85 | Methacrylic silane | | | | | | | | | |
| Aktisil EM | Sillitin Z 86 | Epoxy silane | | | | | | | | | |

The Government of Qatar reported its first two new cases of influenza, two foreign children
The government of Qatar announced today the first two cases of influenza A (H1N1) detected in this country, two foreign children who had recently visited United States and Austria, respectively.
The two children who showed symptoms of influenza A new arrival in Qatar, are receiving treatment and are recovering, said Minister of Health Abdullah Al Qahtani, in a statement obtained by the Qatar News Agency.
The first case corrresponde a child two years of New Zealand who arrived last Saturday with his family from Austria, and the U.S. also is a child of two years who came from New York on Sunday with a stopover in Bangladesh, the minister added.
Four other Persian Gulf countries-Saudi Arabia, United Arab Emirates, Kuwait and Bahrain, have detected cases of influenza A (H1N1) in their respective territories.
Blog of the Day: Public Health and more. Contributions of an epidemiologist who is experiencing the epidemic of influenza A H1N1
This is all very well because it was providing information and making it accessible, especially to fellow Mexicans that they were demanding, and that half of the problem rarely has the opportunity to expunge all sources to extract the necessary information and media misinform rather than inform us.
Note that when a new disease and it is presented in epidemic form, as was the case, health authorities have put in the worst possible scenario because it is better to err on the side by default, but this action has the unintended effect of spreading alarm in the population. Well have been deployed in phases until the pandemic phase 6 in which we have installed a few days ago while waiting to be activated plans for Phase 6, because worldwide it has been decided to continue with the activities of the Phase 5 (containment of the emergence of new cases and isolation of the treatment-known), we can reflect on what has happened and what is happening at this time.

HBCD is Hexabromocyclododecane is end
Brominated flame retardants (BFRs) have routinely been added to consumer products for several decades in a successful effort to reduce fire-related injury and property damage. Recently, concern for this emerging class of chemicals has risen because of the occurrence of several classes of BFRs in the environment and in human biota. The widespread production and use of BFRs ; strong evidence of increasing contamination of the environment, wildlife, and people ; and limited knowledge of potential effects heighten the importance of identifying emerging issues associated with the use of BFRs. In this article, we briefly review scientific issues associated with the use of tetrabromobisphenol A, hexabromocyclododecane, and three commercial mixtures of polybrominated diphenyl ethers and discuss data gaps. Overall, the toxicology database is very limited ; the current literature is incomplete and often conflicting. Available data, however, raise concern over the use of certain classes of brominated flame retardants. Key words: BFRs, brominated flame retardants, HBCD, hexabromocyclododecane, PBDE, polybrominated diphenyl ether, TBBPA, tetrabromobisphenol A.
