About Green Crusaders

GreenCrusaders.com belongs to two recycling enthusiasts, Don Theseira and Mylene Ooi, who started their household waste recycling project in 1996.


This retired couple are based in Bukit Mertajam, Penang but have travelled across Malaysia to educate various organisations, corporations and residents’ associations on the need to recycle household waste. They also teach the art of composting household scraps, using a method which Don has perfected over the years.


Don and Mylene have successfully combined recycling with charitable causes by donating the proceeds of each recycling project to charity organisations.

Besides being featured in countless magazines and newspapers over the years, they have also been awarded the title “Everyday Heroes” by Readers’ Digest in 2002 for their tireless efforts in helping the environment.
