In an aspect a method of manufacturing an acoustic floor panel is described. The method may include: combining a binding agent with plastic flakes; passing the plastic flakes and the binding agent to a lamination machine; applying a force to the binding agent and the plastic flakes using the lamination machine to create a plastic sheet; cutting the plastic sheet; and adding an acoustic insulator to at least a first side of the plastic sheet. 1. A method of manufacturing an acoustic floor panel , the method comprising:combining a binding agent with plastic flakes;passing the plastic flakes and the binding agent to a lamination machine;applying a force to the binding agent and the plastic flakes using the lamination machine to create a plastic sheet;cutting the plastic sheet; andadding an acoustic insulator to at least a first side of the plastic sheet.2. The method of claim 1 , adding the acoustic insulator comprises attaching the acoustic insulator to the plastic sheet using a hot melt adhesive.3. The method of claim 2 , wherein attaching the acoustic insulator to the plastic sheet using a hot melt adhesive comprises curing the hot melt adhesive in a lamination machine.4. The method of claim 1 , wherein the binding agent is a thermally activated binding agent and wherein the lamination machine is configured to apply heat to the binding agent and the plastic flakes while applying the force to the binding agent and the plastic flakes to cure activate the binding agent.5. The method of claim 4 , further comprising claim 4 , prior to cutting the plastic sheet claim 4 , cooling the plastic sheet.6. The method of claim 1 , further comprising adding a decorative layer to the plastic sheet.7. The method of claim 6 , wherein the decorative layer includes any of:wood veneer;carpet;vinyl; andartificial grass.8. The method of claim 6 , wherein adding the decorative layer to the plastic sheet comprises laminating the decorative layer to the acoustic insulator using a lamination ...
