Resolving the environment variable from a file

Hi,

I an having some environment variables exported and the variable name is present in the file. But its not resolving with following commands. Can someone throw some light.
Code:
db $ grep -v "^#" TD_FWK_NUCLEUS.dbc | grep -v "^$" | xargs -i echo {}
wb_bin: ${TD_FWK_NUCLEUS_DBC_WB_BIN_TAG}

I wanted the value instead of the variable name.

Expected output :
Code:
db $ echo "wb_bin: ${TD_FWK_NUCLEUS_DBC_WB_BIN_TAG}"
wb_bin: /opt/teradata/client/13.0/tbuild/bin

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
