Banana is a climacteric fruit that increases its respiration and produces a lot of ethylene during its postharvest phase. They are usually harvested at a stage prior to ripening for transport and then artificially ripened in ethylene chambers. Banana quality can be seriously affected if bananas produce moderate amounts of ethylene during transport. Ethylene affects bananas in ways that: It accelerates ripening and over-ripening. Softening and causing loss of firmness. Alters the color of bananas causing yellowing. It suffers a higher incidence of rots and microbial infections such as: Calletotrichum Musae, Botrytis Cinerea or Lasiodiplodia Theobromae. Lower lot homogeneity after artificial ripening. To avoid wastage, measures must be taken to ensure that green bananas are not exposed to ethylene until artificial ripening is required. The most common diseases due to the effect of ethylene are obvious to the naked eye. Anthracnose, caused by Colletotrichum Musae, is a typical post-harvest disease that is evident on ripe bananas, showing wounds and skin openings. The removal of ethylene during transport delays the development of anthracnose after artificial ripening. In the case of the banana crown, it is common to see its rotting or degradation during postharvest. Crown rot is usually caused by Lasiodiplodia Theobromae, among other fungi, showing dehydration and blackening during ripening. This is activated by ethylene creating a degradation of the skin that invades the whole fruit. To avoid uncontrolled ripening, it is necessary to eliminate ethylene and prevent fungi from proliferating. BION's Transprotekt filters and Ethyl Stopper sachets have an antimicrobial action that extends the shelf life of bananas while removing ethylene from the environment thanks to the action of potassium permanganate. The use of Transprotekt filters and Ethyl Stopper sachets: Increases the shelf life of the product Reduces waste due to over-ripening or spoilage Maintains batch homogeneity after artificial maturation Eliminates odors in cold stores Avoids complaints, returns, renegotiations from customers Allows to benefit from price fluctuations Harmless to workers, bananas and the environment Maintains the color of the banana Easy to handle and inexpensive Compatible for use in organic products
READ MORE »Rising energy costs force us to think of new ways to reduce our energy consumption in air filtration and air conditioning installations, in addition to the need to reduce CO2 emissions. When renovating and designing new ventilation and air filtration systems, it is essential to apply energy-saving solutions without sacrificing performance. Many factors affect energy consumption, the most commonly known are fan operation, cooling/heating of HVAC system and % of renewed air, particulate filter type and maintenance, and molecular filter choice including pellet shape and size which also have a significant impact on energy costs. The importance of the blower operation The cost associated with the blower will depend directly on the operating time, and the consumption, which in turn will depend on the power and efficiency of the blower, the airflow to be treated, and the pressure drop. Two parameters can be adjusted from this equation, the airflow to be treated and the pressure drop. Air conditioning conditions are crucial Air conditioning costs and filtered airflow can be optimized by adjusting the ratios of mixing outside and recirculated air. For this, it will be necessary to consider both indoor and outdoor air quality and pollutants, indoor and outdoor temperature difference, and the humidity of the external air to be filtered. Air conditioning costs and filtered airflow can be optimized by adjusting the ratios of added outside air and recirculated inside air. For this, the quality, temperature and humidity of the outside air to be filtered and the interior air's quality must be considered. How to reduce energy costs by achieving the right pressure drop When renovating and designing ventilation and air filtration systems, it is critical to find solutions that allow us to reduce energy consumption and its associated cost. One of the most important parameters to reduce energy costs is achieving the right pressure drop. Pressure drop can be reduced through the correct selection of equipment, filter media and particle filters. Right filters and media can help reduce more than 10 % of consumption The selection of filter media must be adequate for the elimination of polluting gases in the atmosphere, however, the selection of a media in the form of pellets instead of spheres will considerably reduce the pressure drop (between 10 and 20% for passage speed between 0,5 y 2,5 m/s), reducing the costs associated with the power of the blower. The kWh used by the blower is directly proportional to the pressure drop, meaning that the kWh and their cost will be also reduced by more than 10%. The design of the equipment must be according to the room conditions. Equipment selection is another important parameter to consider. The design of the equipment and the type of media to be used must be specific for each case, depending on the parameters to be considered and the room conditions. However, in general terms, it can be concluded that equipment with bulk media will generally have a higher pressure drop for a standard passage speed of 0.5 m/s, compared to equipment with modules with filter media in its structure. Bulk media equipment typically has a higher bed height. Instead, modules containing thin layers of media can be used inside side access unit-type equipment with a lower pressure drop at the standard velocity of between 1.27 to 2.54 m/s. Save up to 30% of energy costs by optimizing equipment design and selecting the right filtration media. The decrease in pressure drop by optimizing the equipment design and correctly selecting the filtration media can be up to 30 %. This means that lower power will be needed, decreasing the initial cost of the blower. Moreover, having this decrease in pressure drop translates into a decrease in the yearly operation cost due to a lower energy consumption of the blower of over 25 %.

The demand for kiwifruit is increasing year after year due to the boom in consumption of the fruit and its high nutritional properties and pleasant taste. Kiwifruit is a highly sensitive climacteric fruit and as little as 5-10 PPB (parts per billion) of ethylene will induce general softening. This means that exposure of kiwifruit during harvest, transport and storage should be avoided. More and more producing countries are exporting around the world, posing a logistical challenge for a fruit that is extremely sensitive to ethylene. Scientific studies have shown that ethylene has negative effects on kiwifruit: - Accelerated ripening and overripening. - softening and loss of skin firmness - White central inclusions - Increased incidence of rots and mycobacterial infections. - Green core due to overripening - Aggravates pericarp translucency - Kiwifruit wilting and weight loss due to increased respiration BION with its TRANSPROTEKT filters and ETHYL STOPPER sachets delays ripening and increases the storage time and shelf life of kiwifruit.

READ MORE »Ethylene and Volatile Organic Compounds have a very close relationship with fruit ripening and skin weakening leading to significant yield losses. It is known that climacteric and non-climacteric fruits have a unique odor. These odors are actually Volatile Organic Compounds that are emitted by the fruit and become a signal that attracts pests and pathogens. The mixture of volatiles such as limonene, acetaldehyde and ethanol induce the germination of fungal spores such as Penicillium that attack the surface of the fruit. These different fungal species colonize the fruit and emit large amounts of ethylene. Ethylene is also a chemical signal that tells the fungi to attack the fruit, so the infection process feeds back and accelerates causing fruit degradation. An effective way to prevent this cycle of chemical signals from continuing is to adsorb the ethylene with products developed specifically for this function, such as BION's Transprotekt Sachets and Filters. In this way, the ethylene emitted is neutralized, the chemical signals that attract fungi are cancelled out and the firmness of the skin remains intact, allowing the shelf life of the fruit to be extended. Eliminating ethylene from fresh produce is crucial for extending shelf life during post harvest. BION’s wide range of products and technology can help you eliminating it from the environment.

READ MORE »The energetic crisis is increasing the need to reduce the energy consumption of air filtration and air conditioning installations due to its high energy cost and the need to reduce CO2 emissions. For this reason, when renovating and designing ventilation and air filtration systems, it is essential to find solutions that reduce energy consumption and its associated cost. The annual energy cost of these installations is related to the blower and the air conditioner (air heating, cooling or humidifying the air in the work area). The cost associated to the blower will depend directly on the operating time, and the consumption, which in turn will depend on: the power and efficiency of the blower, the air flow to be treated and the pressure drop. The last two parameters, the air flow to be treated and the pressure drop, can be adjusted. The air flow can be optimized by adjusting the ratios of mixing outside and recirculated air. Moreover, air conditioning costs will also be reduced if more air is recirculated but both indoor and outdoor air quality and pollutants must be evaluated, together with the temperature difference, and humidity. The pressure drop can be reduced through the correct selection of equipment, filter media and particle filters. The selection of filter media must be adequate for the elimination of polluting gases, however, the selection of a media in the form of pellets instead of spheres will considerably reduce the pressure drop (between 10 and 20% for passage speed between 0,5 y 2,5 m/s), reducing the costs associated with the power of the blower.

Having this decrease in pressure drop translates into a decrease in the yearly operation cost due to a lower energy consumption of the blower of over 25 %. As air filtration experts, we know our equipment, and our media, and we are able to efficiently advise to maximize resources and improve OPEX.
READ MORE »It is a fact that corrosion has a significant economic impact on an industrial scale. As an example, the results of a study carried out in the USA showed that the estimated annual cost due to corrosion was $276 million, which is approximately 3.1% of the country's gross domestic product (GDP). It is logical then that, during the last decades, great efforts have been invested to face this problem and significantly improve corrosion management, offering better solutions, better equipment and new materials adapted for this purpose. But what do we mean by "corrosion"? It can be defined in many ways, among the different meanings, we could say that corrosion can be the deterioration of materials by chemical interaction with their environment. Although the term corrosion is sometimes also applied to the degradation of plastics, concrete and wood, but in general it refers to metals. The main problem is corrosion occurring in large industrial plants, such as power plants or chemical processing plants, where corrosion can even lead to plant shutdowns and/or production stoppages, with the economic consequences that this entails. In particular, the paper industry is one of the industries most susceptible to this problem, which is why they invest in systems to reduce and control corrosion levels. Project Description BION has extensive experience in this sector and in recent years has improved the solutions suggested to avoid equipment failures due to corrosion. In the last 4 years Bioconservacion has supplied a mixture composed of BION ISORB and BION DOD to a pulp and paper plant located in Uruguay, specifically at the UPM plant in Fray Bentos. This plant is located on the banks of the Uruguay River, 4 km east of the city of Fray Bentos in the province of Rio Negro, and has a production capacity of 1.3 million tons per year of bleached eucalyptus short-fiber pulp for the manufacture of glossy paper and tissue paper. PBS (Parallel Bed Scrubber) equipment was installed in this plant to prevent the deterioration of electrical components due to corrosion. The PBS equipment is a system similar to a SAH equipment, where the filter media are packed in bulk instead of using modules. This type of system can treat horizontal flows between 425 and 54,000 m3/h. On this occasion, the installed equipment is composed of two treatment stages, each with specific filter media in order to obtain maximum efficiency in the elimination of complex air emission. After studying the composition of the main pollutants present in the installation, Bioconservacion suggested two filter media, which in combination can successfully remove most of the problematic compounds present in the stream. This specific mixture is composed of BION ISORB and BION DOD. BION ISORB is designed to successfully attack a wide range of gases. It is especially recommended for the control of acid gases, nitrogen containing compounds, sulfur compounds and low molecular weight gases. BION ISORB uses a combination of two processes for contaminant removal. One of a physical nature, trapping the molecules inside the pellet due to its large internal surface area and a second by chemical oxidation. The oxidized gases are converted into harmless products. A particularity of BION ISORB is that it maintains its effectiveness even in the treatment of streams with relative humidity contents up to values above 95%. This filter media is commonly used in applications such as wastewater treatment plants, pulp and paper plants, airports, chemical plants, refineries or laser cutting and engraving plants. In turn, BION DOD is a high purity, high surface area, bi-impregnated activated carbon that effectively neutralizes acids. BION DOD is a filter media widely used in water treatment plants, it has a very high H2S absorption capacity and is very useful for the treatment of mercaptans and other volatile organic compounds. It is a filter media especially suitable for neutralizing acidic compounds. Evaluation UPM Fray Bentos has been working with this PBS equipment and BION ISORB and BION DOD filter media to effectively prevent corrosion for 4 years. The client has been able to extend the life of its equipment and save costs due to maintenance shutdowns. Bioconservacion also offers the service of performing an analysis of the remaining life of the filtering granulates, halfway through their estimated life, in order to re-optimize the replacement of the granulate mixture in the event that the actual working conditions differ from the initial conditions taken into account in the characterization.
