This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.
The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA spectrometer. The concentration of the elements is determined from the integrated analytical signal and is calculated using a preset calibration graph. The samples of food products are digested prior to analysis in accordance with standard methods.

Energy recovery from municipal waste is the conversion of non-recyclable waste materials into usable energy like heat, electricity, or fuel through a variety of processes, including combustion, gasification, pyrolization, anaerobic digestion and landfill gas recovery. This process is often called waste to energy by the industry.

Food waste in general has a high energy density. This results in high yields when producing biogas through anaerobic treatment. Biogas is a very flexible energy product with proven capabilities in the power, transportation, and heat demanding sectors. In this sector, anaerobic digestion offers significant cost advantages over traditional disposal methods. By upgrading the biogas into natural gas using a DMT Environmental Technology system, a solid business case with an interesting return on investment is assured.
