    Determination of heavy metals in food

    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.

    Scrap Metal Recycling

    Recognized as an industry leader in shredder recycling, we operate 50 recycling facilities for metal, green waste, plastic, food waste, rubber, tires, RDF waste. Harden’s facilities are designed with safety and efficiency in mind for both employees and customers. Our equipment is maintained and updated regularly and our scales are calibrated quarterly. The properties of metals provide unique benefits and advantages for their recycling. Unlike other recycled materials, such as paper and plastic, metals can be repeatedly recycled without degradation of their properties. Metals from secondary sources are just as good as metals from the primary sources. The scrap metal recycling lines are extremely heavy duty systems designed for processing scrap steel, electronic waste, aluminum castings and profiles, ect. We offer both medium and high capacity plants which benefit from low maintenance & operational costs, and lower capital investment when compared with the traditional systems.

  • Metal cutting for the metal recycling industry

    Because metal scrap arrives for re-melting in many forms, it must first be processed. Heavy, bulky scrap should be densified and sheared in a guillotine scrap shear.

  • Laser & Plasma Cutting

    Laser & Plasma Cutting fumes are Unbreathable. Using laser or plasma cutting equipment on either metals or plastics introduces several known carcinogens, such as fused silica and ethyl acrylate, into the air. Occupational Health and Safety organizations recommend reducing personal exposure to the lowest level feasible. Hand held plasma cutting provides metalworkers with a quick and fast way to cut large sheets of metal material. However, plasma and oxy cutting generate a large amount of sparks, slag and fume which can contain different pollutants depending on the type of material being cut. Diversitech's line of downdraft tables incorporating the plasma cutting kit are designed to extinguish the sparks and slag, using heavy duty steel bar grating and a gravel filled baffle tray while the blower pulls away all of the toxic plasma cutting fumes. When considering how to capture and filter the fumes generated from large CNC plasma cutting and laser cutting machines, a large central dust

    Optical Sorting Machines for single stream

    Irrespective of the used collection system and the corresponding task, we design systems that grant 100% efficiency. Various countries have different waste collection systems, resulting in different tasks for the sorting technology. For example, packaging waste mainly consists of plastics, paper and glass. Single-stream waste mainly consists of dry, mixed waste (paper, cardboard, films, plastics, metals, aluminium, and in many cases also glass). Heavy, mixed waste often also contains bulky materials etc. The integration of REDWAVE sorting machines into a waste treatment plant grants maximum purity of the sorted fractions.

    Municipal Solid Waste (MSW) Recycling

    During recent years, the importance of alternative energy sources has become increasingly apparent. With the Eldan Recycling System for MSW (Municipal Solid Waste), you can turn loose, baled or bagged waste like non-recyclable plastics, paper cardboard, mattresses, carpets, etc. into energy in the form of RDF (Residual Derived Fuel). RDF exploits the energy content of the traditional household waste (MSW) to substitute traditional fuels, thus posing an alternative that is attractive both environmentally and economically. Before the waste can be used as fuel however, it must be sorted and volume reduced into a homogenous fraction size of e.g. up to 50mm / 2 in. By downsizing the waste in the MSW Recycling System, liberated ferrous metals, heavy materials (stone, brick, iron) and wet material with low calorific value (smaller than 13MJ/kg) can be removed. The final product (approx. 75% of input material) is RDF with a high calorific value at approx. 26-28 MJ/kg, perfect as fuel ... ...
