5 Green trends


Like all manufacturers in the construction machinery industry, Doosan is working hard to improve and adapt its products to make them more environmentally friendly.  There are 5 top trends in the “greening” of heavy construction equipment*.


1. Reusing and recycling

Reusing and recycling “Most manufacturers have set up rebuilding operations for components or sometimes for whole machines. Under certain programmes, a dealer can take back a used machine, replace its old components, repaint it and sell it with a serial number that designates it as remanufactured. That’s one way of recycling.”


2. Reducing waste

Reducing waste“On-board computers that measure engine usage are becoming increasingly common. When an operator has a pause in his work and is just sitting there idling, the on-board computer automatically reduces the engine speed to idle.  This saves fuel, emissions and money.”


3. Cleaning up Diesel fuels

Cleaning up Diesel fuels “The new regulations for diesel emissions in Europe and in the USA mean that, by 2014, construction machinery must sharply reduce emissions of nitrogen oxide and soot. The downside is that the machines with the new filters and other redesigns may cost 25 percent more.


4. Using more renewables

Using more renewables“Particularly in Europe, there has been a shift toward using hydraulic fluids made from renewable sources such as soybean and rapeseed oils. Most manufacturers have come out with non-petroleum oils that still meet all requirements for wear and tear.”


5. Lowering CO² emissions

Lowering CO2 emissions“Manufacturers are introducing hybrid machines that use batteries to save the engine from powering parts of the operating cycle. Also, some manufacturers are experimenting with smaller-than-normal engines that power a generator. The result is significant reduction of fuel consumption, resulting in a lot less carbon emissions.”
