ABSORBENT POWDER FOR OILS AND SOLVENTS

Absorbent powder is the easiest and quickest solution to clean up accidental spills of dangerous and polluting substances.


In case of spills and accidental leakage


A quick response with the right products in these cases ensures effective and immediate clean-up of worksites or transit environments.

Sepiolite is still the most used powder to remove oil stains from surfaces. However, it’s a poorly performing solution, due to the large quantity of product needed, with high waste volumes, and to the less-than-perfect cleaning of the floors.

Airbank has compared the performance of this traditional mineral with its innovative absorbent products Firesorb, Stone Universal Sorb and Oko-Pur. The results of the tests, carried out at the company's lab, are significant.

Testing methods
To carry out the tests, a block of cement was stained with 100 grams of waste oil (one of the most difficult oils to absorb), which was then absorbed with a known quantity of products.
For each test, the powder used was weighted in a glass, using enough powder to completely absorb the stain.
The result evaluation has been carried out considering two factors:
  1. Weight absorption capacity (how many kg of oil are absorbed by 1 kg of powder)
  2. Surface cleaning level

SEPIOLITE
The first test was carried out using the sepiolite.
To absorb the 100 g oil stain, 4 powder glasses were used (600 grams). The absorption power was 16.7%. At the end of the test, the surface was still soiled and oily.

Different results for Airbank products

AIRBANK > FIRESORB
The first test was carried out using Firesorb.
In this case, to absorb the same oil stain, 2.5 glasses of powder were used (100 grams). Firesorb absorption power was 100% (6 time higher than sepiolite’s).

AIRBANK > STONE UNIVERSAL SORB
The second test has been carried out using Stone Universal Sorb.
With Stone Universal Sorb, 2 glassed of powder were used (70 g): absorption power of 143% (8.5 times higher than sepiolite’s).

STONE UNIVERSAL SORB - Assorbente minerale per qualsiasi tipologia di liquidi

Mineral absorbent for all liquids
Is a natural mineral absorbent for oils, solvents, thinners, acids, paints, inks, lubricants, refrigerant lubricants, fats and food products. Stone Universal Sorb absorbs any liquid or semi-liquid product of organic, inorganic, synthetic or natural origin, from absolutely any surface.

AIRBANK > OKO-PUR
The last test has been carried out using OKO-PUR.
This powder was the most performing: to absorb the 100 g oil stain, 1.7 glasses were used (50 g). Its absorption power was 200% (12 time higher than sepiolite’s).
Furthermore, differently from sepiolite, at the end of the test the surface was perfectly clean and not oily, thus it was possible to transit over it without any risk.

OKO-PUR - Assorbente legante in polvere e granuli a saturazione totale

Full saturation oil binder in powder and granulate form.
Specially designed to absorb oil, grease, petrol, diesel oil, paints and chemicals on the floor of working areas. It is a user-friendly product, with unique features. For example, OKO-PUR can even absorb oil in water, forming large agglomerations which can then be easily disposed of.

DISPOSAL
Hypothesising to purchase and store a quantity of powder necessary to absorb the leakage from a 200 kg oil keg, I’d have to store:
PRODUCT NAMEREQUIRED QUANTITYPARI A SACCHI
SEPIOLITEequal to 1200 kg240 x 5 kg bags
FIRESORBequal to 200 kg36 x 5.5 kg bags
STONE UNIVERSAL SORBequal to 140 kg28 x 5 kg bags
OKO-PURequal to 100 kg15 x 6.8 kg bags

Hypothesising the absorption of 200 kg of oil, considering the exhaust product disposal costs (powder used + oil absorbed), which are calculated “by the pound”, I’ll have to dispose of the following quantities:

PRODUCT NAMEQUANTITY TO BE DISPOSED COSTI
SEPIOLITE1400 kg-
FIRESORB400 kgcost 3.5 times lower than SEPIOLITE
STONE UNIVERSAL SORB340 kgcost 4 times lower than SEPIOLITE
OKO-PUR300 kgcost 4.7 times lower than SEPIOLITE
