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

Working Areas of CRT/N• Biomass-based Programme

• Household/ Institutional Improved Cooking Stoves (ICS/IICS), rocket stove

• Bio-briquette/Charcoal • Hydro-based Programme

• Improved Water Mill (IWM), electrification• Hydraulic Ram Pump

• Solar-based Programme• Solar cookers • Solar dryers

• Technological Innovation• Livelihood enhancement• Gender Mainstreaming and Social

Inclusion• Climate Change

• Clean Development Mechanism (CDM) and Verified Emission Reduction (VER) projects

• Adaptation Projects• Livelihood Enhancement• Networking

CRT/N’s Involvement in Development and Promotion of Clean

Cookstoves• 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

CRT/N and Clean Cookstove

CRT/N and Clean Cookstove

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

Project area

• ICF :SNV supported

• Hariyo Ban: USAID supported

• R&D for household and institutional: SNV/IUCN supported

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
