Chemical disposal
Has anyone in NSW heard the rumour that the Department is going to do another chemical disposal collection this year?. I have a tonne of chemicals to dispose of (only a slight exaggeration) due to a refurbishment of the chemical store and a couple of labs. I got a quote and it was close to $3,000 so I would prefer to wait if they are going to do another collection.

Hi
I believe that the department is doing a chemical disposal this year. I have asked my principal to find out as I have chemicals I need to dispose of. If I find out anything I will contact you at a later date.

I have also heard that they are reviewing the chemical safety package. Part of that review could include whether to have another chemical collection. If not our school has had a quote from Plastech, Gerald ph9623 0888. You must have a lot of waste to get a quote of $3000. My school had only $114 worth of waste.

I too have some chemicals in need of disposal
does any one know who to contact in the department to find out if a collection service is available through them?
any info would be greatly appreciated
thanks m

Hi Dee,Physics One, m & everyone
there is no immenent pick up of chemicals from the DET
however for those in Sydney you can access a free disposal of most of your chemicals through the
CLEAN OUT collections organised by the Dept of Environment and Conservation
for further info
http:/www.<URL removed, see forum rules>
for details on your local site and date for collection
they take household and small NOT COMMERCIAL quantities of most of the chemicals
best of luck

chemical disposal
Hi All
On the subject of chemical disposal: I am updating all my MSD sheets as most of them are more than 5 years old.Phew!!! What a job.Anyway I have come across a tin of very old calcium carbide that is rusted!!! Do any of you know if this is a problem and if it needs to be disposed of? As I am in the far west,disposal is a problem unless we have a pick-up that takes in the whole of the western area.Don't know when this is likely to happen!!!
I look forward to your replies.
Cheers

Calcium Carbide
Hi Mother,
Keep the Chemicals that you have segregated according to the methods you have but place a sticker on the Chemical/s that need to disposed of. This way if the chems are put together and pushed to one side there could be a chance of combinding incompatible chemicals.
This method will give a much safer means of stoirage until it is time to dispose of them. Then simply gather the chemicals that have the labels on them and go from there. Keep in mind too, that if a chemical is old so is the container that holds it as well...
Organic Waste - Keep these in a Fume Cupboard until collection can take place and periodically re-open the lids to release any pressure that may have built up from the addition of different types of organics. *This is why it should be left in the fume Cupboard.
Calcium Carbide can be a bit of a problem when it comes to long life storage. It is very susceptible to moisture (in which it is Dangerous When Wet), and certainly easily oxidised.
To dispose of this substance is quite simple. Depending on the quantity it may take some time but at least when the process is finished there is not need to worry any longer.
In a 1L beaker or larger if you have one, add enough water to fill the beaker to around 3/4 full. Then drop 250g of calcium carbide into this and wait until the reaction has completed. (Although the Calcium Carbide is Dangerous when Wet these quantities I have given you will offer a safe work method).
The liquor or Liquid can be poured into the sink and the solid left over particulates can be absorbed in some saw dust from Wood Work and disposed of in normal solid waste.
I hope this has eased some doubt into the Calcium Carbide problem.
Cheers,
Robb..........
