New types of absorbent industrial, based on polypropylene microfibre, are presented as of the present and the future alternative to the use of the old absorbent granules. They represent an improvement in the environmental management in the efficient use of resources, efficiency, cleanliness, security and the prevention of labour risks inherent in industrial activity.

Absorbents are an indispensable tool in factories and warehouses to control and prevent spills, prevent accidents, keep workplaces clean and safe, prevent pollution and environmental damage as well as preventing damage to people and surfaces.

Industrial absorbent can be, microfibre of polypropylene with different presentation formats such as cloths, rolls, cushions or worms, or grain, on the basis of minerals like clays and sepiolitas or based on organic materials such as peat.

Absorbent granulate

Absorbent granulate.

Until recently, the absorbent granules as the sepiolitas, or the well known 'sacks of sawdust' were the stars as collection spill was being its everyday use and frequent in industries, although gradually storage sacks are giving way, and becoming increasingly more obsolete with the new concepts of industrial absorption, more modern, more effective and more efficient.

We could say that you there is a tendency to use the new absorbent of polypropylene as a new paradigm of understanding industrial cleaning, spill control, environmental awareness and ultimately, safety and risk prevention.

Advantages of Densorb Sepiolitas or traditional granules

-Increased capacity of absorption of polypropylene

The traditional granules absorb less liquid than its own weight. Desorb cloths, on the contrary, absorb up to 16 times its weight of pollutant liquid.

-The use and disposal require less time and effort

The granules are spread on the fluid and the spill should be 'entered' manually in the grain, and must ensure a long time of action between the two. After a long period, reflected the granulate using a shovel or broom and you must enter in a litter bin or appropriate bucket. Very often, moreover, of grain at the scene of the accident remains or slip below machines, banks, etc.

Densorb cloths are placed simply on the spill and absorb liquid immediately: the below and the surrounding of the cloth. The cloth is collected and, with the ability of absorption, dripless. The workplace is completely clean and ready to continue the work. Cloths, therefore increasing productivity.

-Clean machines and work benches aspect

The granules are dirty, dusty and difficult to remove. They slip under machines and banks work, and to be caught up in the soles of the shoes, can be dispersed to other areas of greater sensitivity.

-Occupational safety

The absorbent Densorb not affect in any way the health or safety of persons. Its surface is safe and stable. In contact with liquids, the granules can cause slippery surfaces. Scattered grain, moreover, can be harmful to health, eventually as it can lead to silicosis (dust accumulation in the lungs).

-Benefits in waste disposal

The absorbent impregnated with Densorb can simply pick up the soil and be easily eliminated. In the case of the granules elimination represents a greater effort and more time is needed. Grains should sweep is and take it with a shovel to deposit them in the container of waste. With the poor ability of combustion, elimination by incineration of waste granulates needs a large input of energy. The mineral granules, Furthermore, produce a residual ash for more than 90%. For his great energy power, absorbent cloths are ideal for its elimination through combustion and subsequent reuse of thermal energy. There is only a 0.02% ash residue, so minimizing the costs of disposal.

-Costs

The use of absorbent of polypropylene with the granulated saves material, labour and costs of waste disposal. Although in principle, the price of grain might be more attractive, must take into account that his weight and therefore the price is greater to be handed over to the waste management companies. A greater amount of absorbent granulate is needed to absorb a waste if the absorbent is of polypropylene.
