Methods and systems for producing energy from waste materials

A process for treating solid waste comprising:

• separating the solid waste by type and dosing all of the separated solid waste according to a type of solid waste into a first end of a segmented gasifier, such that a ratio of each type of solid waste being introduced into the first end of the segmented gasifier is controlled, wherein the first end of the segmented gasifier comprises a first segment detachably connected to a second segment;
• gasifying the solid waste as it traverses from the first end of the gasifier to a second end of the segmented gasifier;
• producing a gaseous output and a solid output at the second end of the segmented gasifier,
• separating the gaseous output and the solid output;
• and
• introducing a portion of the gaseous output to a burner and recycling a portion of the gaseous output to the segmented gasifier as an energy source, wherein
• the solid waste is municipal solid waste that comprises more than one of recyclables, wet yard waste, dry yard waste, liquids, sludges, and rubberized products, and
• the type by which the solid waste is separated includes the recyclables, wet yard waste, dry yard waste, liquids, sludges, and rubberized products.
