A method of forming end-form structures from recycled plastics includes i) providing molten agglomerated plastics in noodle form; ii) delivering the molten agglomerated plastics to a shaper; iii) forming an end-form of agglomerated plastics in the shaper by controlling movement and/or position of the shaper, the end-form comprising the agglomerated plastics welded together with voids therebetween; and iv) cooling at least an outer profile of the end-form to form the structure.
