Introduction of CRT/N
•
Established above 2 decades ago
•
•
•
To
develop,
promote
and
disseminate
environmentally
sound
rural/appropriate
technologies
To strengthen capability of rural communities in
creating better opportunities through mobilization of
local resources to improve livelihoods
Disseminated more than 262,000 ICS to remote
households in Nepal with over a million
beneficiaries

Key implementer of Biomass Energy
Support Program (BESP) during first
phase from 2000 to 2005 then
continued as implementing partner till
2013 – CRT/N promoted 208,906+ ICS
out of 637,000 + of BESP
Initiated first CDM project on ICS in
Nepal from 2010 – 14,807 ICS
promoted
A number of projects supported by
various support organizations – about
20,851 ICS promoted
A total of 266,596 ICS promoted by
CRT/N by December, 2013

Social assistances of ICS
• Health improvement through improvement of indoor air
quality
• Income generation opportunities for those involved in
stove promotion
• Institutional capacity building of partner organizations in
managing renewable energy solutions
• Gender mainstreaming and social inclusion

Issues on rocket stove
• Technical issue
•
Breakage of ceramic/ metal
• Social issues:
•
•
•
•
•
•
User’s behavior of using large amount of
wood
Small fire gate
Pot rest depending upon the shape of
pot/ variety of food
Large firewood size
Affordability
Too Tall
