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
![Page 5: Value of bioslurry Steven von Eije, Energy Analyst EDIaal Green Gas.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649cda5503460f949a4b63/html5/thumbnails/5.jpg)
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?
