Legacy Foundation was established in 1999 and works in 45 countries worldwide. Its directors have been working in Tanzania with various appropriate technology and rural development projects since 1974.   The focus on biomass briquettes began  in 2007, with a training of trainers project in Lushoto.   Recently Legacy Foundation partnered with TROSS  (Tropical Solar Systems)  in Arusha Tanzania to support and more consistent response to the requests for training and technical support in briquette making in the country.   Today TROSS and Legacy Foundation are working with a number of briquette producers throughout Tanzania trying to stop the massive increase in the use of charcoal for fuel.   All of that charcoal production is destroying the environment and production and use of  biomass briquettes can help to stop that destruction.   There are now 10 active briquette producing groups in the Tanzania network of briquetters.  

Msingi Legacy ilianzishwa mwaka 1999 na kazi katika nchi 45 duniani kote. wakurugenzi wake wamekuwa wakifanya kazi nchini Tanzania na teknolojia mbalimbali sahihi na miradi ya maendeleo tangu mwaka 1974. Kuzingatia briquettes majani alianza mwaka 2007, kwa mafunzo ya mradi wa wakufunzi katika Lushoto. Hivi karibuni Legacy Foundation ushirikiano kwa TROSS (Tropical Solar Systems) katika mikoa ya Arusha Tanzania kwa msaada na majibu thabiti zaidi ya maombi kwa ajili ya mafunzo na msaada wa kiufundi katika briquette maamuzi katika nchi. Leo TROSS na Legacy Foundation ni kufanya kazi na idadi ya wazalishaji briquette katika Tanzania kujaribu kuzuia ongezeko kubwa katika matumizi ya mkaa kwa ajili ya mafuta. Zote za uzalishaji mkaa ni kuharibu mazingira na uzalishaji na matumizi ya briquettes majani inaweza kusaidia kuzuia uharibifu huo. Sasa kuna kazi 10 briquette huzalisha vikundi Tanzania ya briquetters.
