Our solutions: Products for climate protection
BASF products are involved in a large number of climate protection technologies. Therewith we enable energy efficiency and climate protection in a variety of sectors, such as the construction industry, the automotive industry and in industrial processes.
Our climate protection products sold in 2015 are enabling our customers to reduce greenhouse gas emissions by 530 million metric tons of CO2 equivalents.
Our goal is to continually increase the contribution of our current products for climate protection, as well as of new products and solutions. We invest about half of our annual expenditures for research and development (R&D) on product and process innovations where the R&D target is related to energy/resource efficiency and climate protection.
Examples of our products for climate protection:
Efficient and environmentally friendly insulation materials
Over 50 years ago, BASF invented a classic product for efficient insulation, known worldwide under the trade name Styropor®.
With Neopor®, we have taken this classic a step further. The novel feature of this product is the addition of black graphite particles which improve the insulation performance by up to 20 percent.
Insulating an old building so that the heating energy requirement of 21 liters of fuel oil per square meter per year drops to 7 liters means that less insulation material is needed than when using conventional Styropor®.
Their outstanding insulation properties mean that polyurethane (PU) rigid foam systems are used in a number of cold and heat insulation applications. In addition to energy and cost savings, PU rigid foam offers architects freedom of design and additional living space due to slimmer construction options and as a result is used in house-building in a number of roof, wall and floor applications. Elastopor® and Elastopir® rigid foams are also used as the core material in sandwich panels, for example as facade and roof elements in cold stores and storage facilities. PU rigid foam is also a preferred option in refrigerators and freezers and for insulating hot water tanks, as well as insulation for district heating pipes.
It was in 1964 that BASF began producing this green insulation board. Nowadays, Styrodur® is a synonym for XPS in whole Europe and stands for diverse applications, robustness and highest compressive strength.
In 2015 the new generation was born: Thermally welded Styrodur® with one single Lambda value over the whole thickness range.
Plastics and additives for greater sustainability in the mobility sector
BASF's Keropur® fuel additives are mixed in small quantities with the fuel and produce better combustion in the engine. As a result, fuel consumption is reduced and premature wear on the engine is prevented, which in turn reduces the output of pollutants and greenhouse gases.
A test BASF performed jointly with a leading petroleum company on a fleet of vehicles over 64,000 kilometers showed that a premium additive package reduced pollutant emissions by 20 percent and improved average fuel economy by upto 2 percent. An eco-efficiency analysis comparing fuel with and without additive clearly showed that Keropur® fuel additives contribute significantly to climate and environmental protection.
The use of fertilizers releases large quantities of nitrous oxide through the decomposition of nitrogen compounds in the soil. BASF’s nitrification inhibitor ensures that the ammonium contained in fertilizers is metabolized more slowly by bacteria in the soil, thus resulting in a reduction in nitrous oxide. The fertilizer can supply crops with nutrients more efficiently, and the crop requires fertilization much less frequently. This decreases greenhouse gas emissions. The impact on groundwater is reduced by the nitrification inhibitor as well.
Chemistry makes wind power more economic
BASF supports the continuing development of wind power as a climate-friendly source of energy. BASF’s innovative solutions are a contributory factor in the more efficient manufacturing, coating and maintenance of rotor blades, bases, towers and gears for wind turbine systems.
Our products therefore play an important role in the successful introduction of wind turbine systems for the next generation. In addition to this, our researchers are also working on the development of materials for organic solar cells, fuel cells, innovative hydrogen storage systems and organic light-emitting diodes.
Larger rotor blades help modern wind turbine systems increase performance. Epoxy-based composites have become established as the material for manufacturing these rotor blades. BASF offers appropriate two-component systems under the trade name Baxxodur™.
In order to be able to produce large defect-free blades, the components used in the system should not react too rapidly when filling the molds. At the same time, the epoxy resin systems should not cure rapidly in the mold, so that this is then free for manufacturing the next blade. BASF has developed new Baxxodur™ systems based on specialty hardeners specifically for manufacturing large fiber composite structures. They react slowly when the mold is filled and rapidly on curing, which means that manufacturers of rotor blades for wind turbine systems can reduce production times by up to 30 percent and increase their productivity. BASF is therefore making an important contribution to increasing the profitability of wind power as a climate-friendly source of energy.
As well as the perfect technical construction of the rotor blades, the efficiency and productivity of the wind turbine systems are greatly dependent on the durability and low maintenance of the rotor coating. The surfaces of the blades are subject to extreme exposure to sun, wind, snow, rain and air pollution. BASF’s subsidiary RELIUS COATINGS has been offering special coatings for these demanding requirements for more than 10 years. In the RELIUS Wind Coat system, special materials provide an extremely high weather resistance in the coatings and make it possible to manufacture all products for the multi-layer construction without the need for solvent.
