Abstract

An apparatus and method for disposal of photocurable fluid waste may include a conduit for conducting photocurable fluid waste from a source of photocurable fluid waste; a dispenser for automatically dispensing a receptacle made of material that is impermeable to the photocurable fluid waste and that transmits radiation capable of curing; a welder or other sealing device for welding the receptacle to form a bag with a portion of the photocurable fluid waste inside; and a source of radiation for curing the photocurable fluid waste in the bag.

Claims (11)

1. A method for disposal of photocurable waste, the method comprising:

conducting photocurable waste from a source of photocurable waste through a conduit;

automatically dispensing a receptacle made of material that is impermeable to the photocurable fluid waste and that transmits radiation capable of curing;

sealing the receptacle to form a bag with a portion of the photocurable fluid waste inside; and

curing the photocurable fluid waste in the bag using a source of radiation.

2. The method of claim 1 , further comprising disposing the bag.

3. The method of claim 1 , further comprising sensing the quantity of the photocurable fluid waste in the bag prior to sealing the bag.

4. The method of claim 1 , further comprising detaching the bag from the material prior to the step of disposing the bag.

5. The method of claim 1 , wherein the receptacle comprises two substantially parallel sheets, and wherein the dispenser includes two opposite reels around each of which one of the sheets is initially wound.
