Is this a correct way for passing an environment variable in sudo ?

sudo -u www-data -b env FOOBAR="foobar" /home/user/folder/daemon

That works, but env isn't needed. You can run a test like this:


echo $tst

chmod +x /tmp/test

sudo tst=howdy /tmp/test

It's also possible to get environment variables through using the -E option, which preserves your environment (depending on other settings).
