Abstract
To date, no sustainable way of processing liquid packaging boards as a whole has been defined. The cardboard is occasionally recycled; however, there is no reliable demand for the resulting mixture of polyethylene and aluminum (PE-Al). Since Al leaching from landfills destroys both soil and water, it was proposed to prevent PE-Al landfilling by transforming Al into nanoparticles (Al-n), which would be used as low-cost (bio)diesel additive. It is reported for the first time that the concept has been proved to be technically feasible and financially promising on a pilot scale. A series of tests with a single-cylinder water cooled combustion engine under various loading conditions revealed that the Al-n obtained (375.6 m(2)g(-1)) is capable of significantly increasing the reaction surface of the combustion process which manifests itself by (a) higher brake-specific fuel consumption, (b) enhanced brake thermal efficiency, and (c) significant drops in the production of combustion gases (CO; HC; CO2 and NOx in particular). Nevertheless, data indicate that there are untapped challenges regarding the presence of O-2 and further increasing the surface area of the Al-n. Although the addition of Al-n slightly reduced the oxidative stability and lubricity, these properties can be easily compensated by antioxidants and lubricants.
