Biogas Management School
We are developing economically sustainable biogas technologies that make ecological sense
and we are building high-performance AD plants, which process mostly fibrous biomass
• For the utilization of agricultural by-products and landscape conservation materials
• For the development and improvement of structures in rural regions
• National and international
• With flexible biogas and power production complementary to wind and solar power as
contribution to a turnaround in energy policy

Problems in Kenyas Agro Industry
High energy prices
Unreliable electricity supply
Voltage fluctuation in the grid
World market prices for the products
No utilization of the by products (straw, waste)
Waste problems – sisal, slaughter houses,
A biogas plant is a 1st principle solution
Agricultural By Products
Maize stalks
Pack house waste
Sisal waste
Fruit processing waste
Sisal waste
Coffee husk
Rice straw
Benefits
Stable electrical supply
Lower costs due to savings on diesel for backup generators
Stable frequency – less damage of the electrical equipment – fewer costs
Nutrient recovery – fewer costs
Less pollution
Heat (tea plantations, greenhouses)

Technical Problems to Solve
Snow Leopard Projects specializes in challenging raw materials such as the
digestion of straw and fibrous biomass as well as food production waste
materials, which have a high energy content, which is causing easily
acidification in digesters.
We solve the biological problems with a 2 stage digestion technology with
a separation of hydrolysis/acidification and methanisation.
The Right Feed for
low fiber
high fiber
Advantages of the 2-stage Biogas Technology
with Batch-Hydrolysis
• Higher biogas yield per ton input
• Being able to digest cheaper and more available fibrous raw materials
• Utilization of high-energy raw materials like slaughterhouse waste without
impairing biology
• Seasonally available raw materials can be used as well (fruit waste)
• Independence of world prices of expensive raw materials
• Higher flexibility of both raw materials and feeding
To solve waste, energy, fertilizer and environmental
problems in Naivasha
Gorge Farm Biogas Plant
at Lake Naivasha
Benefits
Production of captive power for the vegetable and the flower farm
Biogas electricity is cheaper then grid electricity and diesel electricity
Stable voltage
Utilization of the heat in green houses and breeding beneficial insects
Fertilizer for higher yields
Nutrient recovery
Soils improvement
Feedstock
• Maize stalks from baby
corn
• Vegetable waste from
food processing
• Agricultural by products
as, broccoli stems,
bean straw from French
beans
• Flower waste
• By products from
various other sources
as other farms
• In total up to 120 tons
per day
The Biogas Plant at Gorge Farm, Naivasha
Technology
2 Stage AD – Separation of Hydrolysis/ Acidification from Methanisation in different tanks
Tanks
2 Hydrolysis tanks (700 m³)
1 Digester (5.600 m³)
1 Final storage tank (700 m³)
Retention time
Ca. 16 – 40 days depending feedstock amount
Fertilizer
Used on the farm
Gensets
2x 1,4 MWel nominal
Due to the altitude the expected load is 1,2
MWel
Investment
6.5 Mio. $ biogas plant + 0.6 Mio $ for farm
equipment
Profitability
Higher than calculated due to higher electricity
prices and heat sales

Challenges in Engineering and Construction
• Seismic active zone – no steel tanks possible, which would have
been easier to construct
• Transport of equipment
• Customs – long procedure
• Work goes slower than in Germany – increases construction
overheads
Challenges in Operation
• Weak inoculum – cattle dung has no bacteria
• Lack of minerals in cattle dung and feedstock
• Fresh maize is different to maize silage

Experiences in Africa
HPTC – High Performance Temperature Controlled
•
Solar thermal heating system
for the operating temperature
•
High-energy raw materials
•
Further regional advancement
through a reliable power supply
Conclusions
A biogas plant for captive power is feasible in Kenya and the
most other countries in Africa
If you can use the CHP heat, it is even more feasible
A biogas plant for electricity production and sales of the
electricity for 10 ct$ is not feasible
