Disclosed is a method of processing a composition comprising soot. The method includes supplying a first composition comprising soot particles to a first chamber. The first chamber is separated from a second chamber with a filter wall located therebetween. The soot particles are collected with the filter wall in the first chamber while substantially passing gaseous components of the first composition to the second chamber. A photocatalyst configured to facilitate generating at least one oxidant is activated, and the at least one oxidant oxidizes at least part of the soot filtered in the first chamber. Further disclosed is a soot processing apparatus, which includes a first electrode, a second electrode opposing to the first electrode, a first cell, a second cell and at least one porous wall. The first and second electrodes create a plasma state between them. The first cell and second cell are located between the first and second electrodes, and each has an opening. The first cell receives through the inlet opening a supply of a first composition comprising soot particles. The second cell exhausts through the outlet opening a second composition substantially free of soot particles. The porous wall partitions the first cell from the second cell and collects soot particles in the first cell while passing gaseous molecules of the first composition to the second cell.
