Abstract
The present invention relates to a method of manufacturing a carbonated plastic aggregate comprising the steps of: (i) mixing plastic particles and at least one cementitious binder comprising at least one metal oxide or metal silicate to form a first composition, (ii) providing a second composition comprising water; (iii) mixing together the first and second compositions to form a pre-mixture; (iv) agglomerating the pre-mixture to form a plastic aggregate; and (v) carbonating the at least one metal oxide or metal silicate by means of an active carbonation process to obtain the carbonated plastic aggregate.
Claims23
A method of manufacturing a carbonated plastic aggregate comprising the steps of:
- (i) mixing plastic particles and at least one cementitious binder comprising at least one metal oxide or metal silicate to form a first composition, wherein the plastic is derived from plastic-based foam;
- (ii) providing a second composition comprising water;
- (iii) mixing together the first and second compositions to form a pre-mixture;
- (iv) agglomerating the pre-mixture to form a plastic aggregate;
- and
- (v) carbonating the at least one metal oxide or metal silicate by means of an active carbonation process to obtain the carbonated plastic aggregate.

A method of carbonating a plastic aggregate pellet comprising:
- i. providing a plastic aggregate pellet comprising a) a plastic particle, b) at least one cementitious binder comprising at least one metal oxide or at least one metal silicate, and c) water,
- ii. carbonating the at least one metal oxide or at least one metal silicate by means of an active carbonation process to obtain the carbonated plastic aggregate.
