How do you recycle styrofoam in Ottawa?
Styrofoam is actually recyclable. Many recycling places won't take it just because they either do not have the right recycling equipment or the amount is too small. If you have a lot of Styrofoam scrap, you can install an extrusion pelletizing production line to produce PS pellets. Many plastics processor will buy these pellets to produce such products as decoration profile. Timbron in California is one of the US companies that is doing this. If you have Styrofoam scrap but in small amount in a location, it is better to compact the foam and then ship the densified logs to recyclers for further processing. here is the supplier of such equipment. www.stryrofoam-compactor.com . Recycled styrofoam is called PS (polystyrene), which can be used to produce many products such as CD cases, coat hangers, KT board, foam peanut, and many others. If you are not recycle Styrofoam scraps, you will have to pay waste management companies to land fill. If you recycle it, you can make money from the business. People can get the money pay back with in 6 to 9 month for recycling Styrofoam. Source(s): http://www.eps-recycling.net/
Asked in Electrical Engineering
Is ohms law true for all materials?
Most definitely NOT! For Ohm's Law to apply, the ratio of voltage to current MUST be constant for variations in voltage. And this is only true for a small number of materials we call 'ohmic' or 'linear' materials -meaning that if we plotted a graph of voltage against current for changes in voltage, we'd end up with a straight line (linear) graph. But most materials are 'non-ohmic' or 'non-linear' -in other words, the resulting graph is NOT a straight line. It can be argued that Ohm's Law, therefore, is not a 'law' at all! Perhaps it's time it was scrapped?
