Environment in the green - finances in the black

The economical use of raw material, the extremely low breakage rate, the recyclability or reusability of the sacks: Each ecological advantage is also reflected as an economical advantage.
As a result of the material characteristics and the special production process, the weight of an average 50 kg AD*STAR® cement sack can be as low as 75g. A comparable 3-layer paper bag will weigh about 180g and a PE-film bag 150g. An economical use of raw material not only helps minimize cost, it is also a valuable contribution to the preservation of our environment.

AD*STAR® for ecology and economy
The impressive reduction of the breakage rate when compared with conventionally used paper sacks has both an environmental and an economical effect:
First, the risk of contaminating earth and water with the filling material is nearly zero. In addition, the savings potential is enormous when you act on the assumption that realistic breakage rates in the life cycle of paper bags (filling, conveying, palletizing, stacking, loading, transporting, unloading, …) are about 5%.

Marketable and recyclable
What is more, most of the breakage occurs not within the cement plants but outside at the distributor and end customer during transport and handling. This is the reason why so many customers ask for the AD*STAR® bag by name! Offering and advertising AD*STAR® bags can give you a huge marketing advantage over your competitors and help you sell your production.

Even after emptying, AD*STAR® bags are a resource.
Recycling is one option because polypropylene is fully recyclable into resin; another possibility is intrusion, also a recycling technology, by which household-grade plastic waste is processed into quality moulded products. There is always the option of burning the sacks to recover the very high calorific value which is almost as high as the energy value of fuel oil. Cement plants all over the world supplement oil and coal with secondary fuels to achieve savings of up to 30% of primary fuels.

However, often this is not going to happen because in many countries, second-hand woven bags are in demand for a variety of practical uses, from growing vegetables to covering roofs.
