Extend the shelf-life of avocado with BION

Avocado is a fruit that is considered a superfood also called "green gold" and has an increasingly widespread use making the export industry grow exponentially. Global avocado production is expected to reach 12 million tons by 2030, 3 times more than in 2010, according to data from Rabobank. One of the biggest logistical challenges is to ensure that the product arrives in the best conditions and without shrinkage. Thus, ensuring the good condition of the cargo during transit becomes a priority.  Once harvested, avocados emit ethylene, which accumulates in storage chambers and transport containers. Some of the effects of ethylene on avocados are: - Accelerated ripening and overripening - Softening and skin color change. - Increased avocado respiration - Increased incidence of chilling injury (vascular and pulp discoloration). - Increased incidence of rots and fungal infections (anthracnose and terminal purple rot). - Reduced lot homogeneity At BION we have the technology and the product to solve this need. The combined use of controlled atmosphere and ethylene absorption technology is the best solution to minimize production loss and extend avocado shelf life. The use of ETHYL STOPPER sachets and TRANSPROTECKT BION filters, allows the product's properties to be maintained and the shelf life to be extended.  As these products do not directly touch the fruit, they are compatible with organic farming.  


WWTPs, how to prevent and control the generation of odorous gases?

There are three commonly used technologies for the prevention and control of odor gases: 1: chemical scrubbing The chemical scrubbing treatment system consists of passing the gas through scrubbing towers where air/water/reagent contact takes place. In chemical scrubbing, an acidic or basic chemical solution is injected into the system from the top, passing through the flow of the gas, and is then recovered at the bottom of the tower for recovery and recirculation. The gaseous compounds are retained in the chemical solution which must be replaced periodically.   This technology has a high operating cost and a high risk associated because of the handling of this kind of chemicals.   2: filtration with solid adsorbents There are different types of solid adsorbents for odor removal, the most common is activated carbon. The gas passes through tanks containing the adsorbent media. The adsorbent media and its ability to remove odorous gases can vary depending on: - The porous structure of the base material (activated carbon, natural clays). - The chemical impregnation of the agents that cause the adsorbent media to react with specific gaseous contaminants to retain them or convert them into non-odorous ones.   Activated carbon filtration is a technology with a low initial investment cost, which does not require qualified personnel for its operation, which makes its use extensive.   The installation of covers in different areas of the wastewater or sewage treatment plant (pretreatment, thickeners, sludge storage, decanter channels (1st and 2nd), allow to mitigate the dispersion of odorous gases and to channel the air flow towards a tank with adsorbent media that allows the filtration of odor causing compounds (H2S, ammonia, sulfides, mercaptans, VOCs).   BION offer solutions consisting of adsorbent media or chemical filter media ( These solutions include virgin activated carbon and other adsorbent chemical media that effectively remove odor gases generated in a WWTP even better and more efficiently than activated carbon solutions.   3: advanced biofiltration (biofilters) The biofiltration deodorization process is based on the action of microorganisms capable of decomposing odorous compounds. They are effective when it is necessary to remove high concentrations of odor compounds or to treat large air flows. The operating cost is minimal. But microorganisms are sensitive to atmospheric conditions of temperature and relative humidity. Also need a constant supply to survive. It can be affected by process stoppages or decreases in the concentration of the compounds reaching the filter.   Each of these systems has its own characteristics, advantages and disadvantages. The most appropriate technology will depend, to a large extent, on the type of gaseous effluent to be treated.


Sick Building Syndrome

The sick building syndrome is a set of discomforts and diseases caused by multiple causes such as poor ventilation, suspended particles, gases and vapors of chemical origin and aerosols, among others. The WHO defines it as the set of diseases caused or stimulated by air pollution in enclosed spaces. The effects on human health associated with the sick building syndrome include: Irritation of the eyes, nose, throat and skin. Headaches, migraine, dizziness and fatigue. Respiratory discomfort. Symptoms tend to increase with increasing time spent in the building and disappear when not inhabited. In this way, Sick Building Syndrome causes a substantial alteration of work performance and interpersonal relationships, as well as a considerable loss of productivity. Some of the gases that cause this syndrome come from common construction materials, furniture, textile materials, paints, wallpapers, floors and even cleaning products, air fresheners and deodorizers. Some of the most common gases present are: Formaldehydes α-pinenes VOC's Tetrachloroethylene Acetones Etc. In BION we have a wide range of medias that are able to eliminate practically 100% of these gases and ensure a good Indoor Air Quality. BIOGRAPHY
