Abstract

An arrangement and a method for mixing and handling industrial side-stream materials. The mixer ( 6 ) is arranged onto a movable work machine ( 5 ) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile ( 4 ) and a casting area ( 13 ) in the mixer ( 6 ). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.

Claims (12)

1 . An arrangement at a factory waste disposal site, which arrangement comprises at least one waste pile of a first industrial side-stream material,

wherein the arrangement further comprises:

at least one movable work machine which is provided with a mixer, and wherein the work machine is arranged to take said first industrial side-stream material directly with the mixer from said waste pile for handling said first industrial side-stream material by the mixer;

an admixture station which comprises at least one feed device for feeding at least one admixture into said first industrial side-stream material located in the mixer of the work machine;

a casting area which is arranged to receive from the mixer a geopolymeric hardenable paste formed by said first industrial side-stream material and said at least one admixture as a result of mixing said first industrial side-stream material and said at least one admixture;

a quarrying device for quarrying hardened paste in the casting area;

a crusher device for crushing material extracted by quarrying to obtain crushed material; and

a temporary storage for receiving crushed material from the crusher device;

and wherein said first industrial side-stream material is kept in said mixer of the work machine from the waste pile up to the casting area.

2 . The arrangement according to claim 1 , wherein

the factory waste disposal site is located in connection with a pulp mill; and

the waste pile is green liquor precipitate, whereby the first industrial side-stream material taken from the waste pile with the mixer is green liquor precipitate.
