An object of the present invention is to not only assume that the generation of carbon dioxide gas is reduced when incineration is performed, but also to store carbon in addition to the presence of uniform bubbles in the interior and suppression of unpleasant odors. The present invention provides a lignin-containing polymer foam that may be evaluated in the future and a foaming resin composition for obtaining the same. A foaming resin composition comprising a polymer substance, 5 parts by mass or more and 100 parts by mass or less lignin and 1 part by mass or more and 30 parts by mass or less of a foaming agent with respect to 100 parts by mass of the polymer substance. It is a thing. [Selection figure] None |
