Mixing of hazardous waste
|From:||ANATECH LTD <email@example.com>|
Formaldehyde does not form explosive mixtures with alcohol or xylene.
However, there may be a reason for not combining them for disposal.
Your waste hauler should be consulted before combining any waste
(even alcohol and xylene), as it may affect the manner in which the
hauler ultimately disposes of it. This in turn wll affect the cost
to you, the generator.
Many disposal firms sell flammable waste to cement companies and
other such industries for use as a fuel or fuel supplement in kilns
and furnaces. Aqueous contaminants lower the caloric value of the
fuel and may render the waste unsuitable for this method of disposal.
As the water content of the waste rises, it becomes more difficult to
burn it in an incinerator and may even require the addition of
expensive high-caloric fuel to destroy the material. This becomes
very expensive and is why, in many areas of the USA at least, the
cost of disposing of formalin is so much higher than that of
Because of cost and liability issues, having waste hauled away should
be the choice of last resort. Minimize the use of hazardous
chemicals, recycle formalin and solvents, and replace with safer,
more environmentally friendly reagents.
