Enzymatic Deinking

Enzymatic Deinking

(OP)
Hi engineers,

I am working on a paper recycling startup. My aim is to establish a deinking plant, which I assumed to be a key for recycling printed paper wastes. I have searched for the deinking technologies and it seems that there are two main methods: chemical-mechanical (floating, washing and a combination of both) and enzymatic method. The enzymatic method is relatively new. I wonder if there is a significant difference between the methods regarding the performance, end quality and economy? Does it worth to go after enzymatic method in a country which the recycling rate is very low? (about 10%).

Maybe the question is very general and novice but I am new in this field and any basic hint is a big help.

Thank you.

RE: Enzymatic Deinking

It depends a lot. f you are planning on an increased recycling rate and think that it is worth-while to be part of the experimental adventure that most pioneering start-ups turn into, then go for enzymatic de-inking.
On the other hand, if you just want to de-ink paper and do it at the lowest cost and with a guaranteed result, then buy a used de-inking plant, hire a guy that was operating it and move it to your part of the World.

The internet has reduced Newsprint demand a lot and there are used de-inking plants to be found at very low cost in most western countries.

Adventure and learning, but probably high cost: Enzymatic.
Safe and sure and lowest cost: Flotation and other technologies.

Thank you so so much. Could you please give me some hint on how to find used plants? Is there any website or special advertising on used deinking plants? I think the best way is to start with a conventional and established method and then doing R&D.
