Value of bioslurry Steven von Eije, Energy Analyst EDIaal Green Gas
Content of presentation • Background • Research Design • Results • Implications
Background • Invitation from SNV to investigate the value of bioslurry • Tea producers (good records of production and expenditures) • Thai Nguyen Province in Vietnam
Research questions • Effect of bioslurry on tea production • Effect of bioslurry use on household income
Approach • Personal interviews (questionnaire and translator) • 100 households • No control group (large wealth difference)(“There is no actual demand for biogas installations, everyone who can afford one, has one because it’s a great product.”) • Historical and current data used
Effect on tea production • Amount of tea produced per sao • Price per kg processed tea • Data used in income calculation
Effect of bioslurry use on household income • Change in production quantity? • Change in price for tea? • Change in amount of pesticide use? • Change in amount of chemical fertilizer use?
Annual income effect in comparison to biogas installation costs
