NOVELTY - Processing of waste liquid, involves spreading earthworm potting soil (3) containing wooden debris on a frame (2), dividing the frame, spreading food residue (4) in frame and digesting by earthworm, decomposing food residue and potting soil and obtaining earthworm excrement containing soil (5), spreading the food residue on one half of excrement soil and removing the other half, spreading potting soil in emptied region and spreading food residue again on the soil, removing the other half of the excrement soil, spreading new potting soil, and decomposing the mixture.    USE - The method is useful for processing of waste liquid obtained from food factories, restaurants, wood wastes e.g. sawdust, and domestic waste. The processed material is useful as organic fertilizer in farmlands.    ADVANTAGE - The method avoids existing incineration or discarding method for waste disposal, and hence reduces the need for more amount of fuels for incinerating waste containing high moisture content, and enables the production of useful organic substance by using earthworms. The method is also environmentally-friendly as it prevents global warming and also enables usage of abandoned land and eliminates coppiced timber.    DETAILED DESCRIPTION - Processing of waste liquid, involves spreading earthworm potting soil (3) containing wooden debris which adsorbed waste liquid from food on a frame (2), dividing the potting soil into several pieces after spreading the potting soil, spreading food residue (4) evenly on the pieces of potting soil, digesting the food residue by earthworm which stimulates the activity of soil microorganisms through its excretion, decomposing the food residue and earthworm potting soil using microorganisms and obtaining earthworm excrement containing soil (5), spreading the food residue on one half of the excrement soil and removing the other half of the excrement soil after processing for fixed period, spreading new potting soil in the region from where the excrement soil is removed and spreading food residue again on the new potting soil, removing the other half of the excrement soil, spreading new potting soil, and decomposing the food residue and the potting soil and obtaining earthworm excrement containing soil.
