Waste processing method and system

A waste processing system comprising:

• a gas separator configured to receive gas, the gas separator configured to separate the gas into one or more constituent component gases comprising at least carbon monoxide;
• a carbon dioxide production unit configured to receive a first portion of the separated carbon monoxide and convert the first portion of the separated carbon monoxide to carbon dioxide;
• a greenhouse configured to receive the carbon dioxide, wherein plants are grown in the greenhouse;
• and
• a waste conversion unit configured to receive waste material and produce the gas from the waste material,
• wherein the waste conversion unit is a plasma reactor or a gasification, incineration, or thermal reactor.

A method including:

• receiving a gas comprising at least carbon monoxide and hydrogen;
• separating the carbon monoxide from the hydrogen;
• converting at least a portion of the carbon monoxide into carbon dioxide;
• feeding the carbon dioxide into a greenhouse including plants,
• wherein the gas is produced by a gas generation process comprising a plasma reactor or a gasification, incineration, or thermal reaction.
