About Us
Alfa Systems & Services was first established in the Year 2005, It is a sister
concern of Alfa Next Gen Tech : formulated in 2008.
From the beginning we have been working successfully in the field of HVAC.
Having realised the importance of Sustainable Waste management and
Sanitation in our society, in 2011 we adopted the DRDO Developed Bio Toilets
& Bio Digester which works with the objective of disposing waste in an eco
friendly manner.
To further this initiative, we also entered a strategic tie- up with IIT Delhi to
promote and bring into utility, the water less loo developed by them,
manufactured and sold by EKAM Solutions Pvt. Ltd.
Our Vision
To ensure that every Indian has access to a dignified and eco friendly toilet experience.
Our Mission
•To eradicate open defecation & manual scavenging.
•To create awareness regarding sustainable sanitation solutions.
•To create awareness with regards to health and environmental issues & focus on community
programs for safety & dignity of women.
•To undertake social projects for installation & maintenance of Bio toilets and Bio digesters
in order to improve national sanitation practices and attitude towards sanitation.
•To Promote R&D in the Bio Toilet technology and sustainable waste management systems.
Vision & Mission
•About 1/7thof world population still openly defecate in the
absence of any toilet / latrine, of which 60% live in India.
•The global impact of poor sanitation on human health and infant
/ child death is profound.
•It is estimated that 10 million children under 5 die globally every
year out of which 2.4 million are in India.
According to UNICEF / WHO estimates:
Eco Convenience Bio Toilet and Digester
•We at Alfa Next Gen Tech India Pvt Ltd. are offering an innovative
technology for disposal of human waste in an eco friendly manner.
•Bio Digesters are cylindrical/ rectangular structure with the provision of
inlet for human waste and out let for Bio gas and Odorless, Harmless Fertile
Water produced by bacteria digesting the Human Manure.
•Bio digesters contains a bacterial consortium which can function from -40 to
+60 Deg Centigrade Temperature/s
•The bacterial consortium degrades the night soil and produces colorless,
odorless and inflammable bio gas containing 50 – 70% methane.
•Bio-Digesters do not require sewage-line connection or additional septic
tanks for disposal of black water or waste from toilets.
•Bio digester disposes human waste in 100% eco-friendly manner and
generates color less, odorless water and inflammable Methane- Gas for
cooking, water heating & room heating etc. as a by product.
•This technology is 100% maintenance free and is a continuous biological
process.

Lack of awareness
Process of Degradation
Hydrolysis
Particulate solubilized and large polymers converted to simpler monomers
Acidogenesis
Simple monomers converted to volatile fatty acids
Acetogenesis
Acetate converted into CH4 and CO2 while H2 consumed
Methaneogenesis
Volatile fatty acids converted to acetic acid,CO2 and H2
Anaerobic Bio Degradation involves degradation of human waste
without the use of oxygen in a closed container.
Process of degradation
•The Tank of Bio toilets is a cylindrical/
rectangular structure with the provision of
inlet for human waste and out let for Bio
gas and water.
•Night soil degradation occurs through
microbial reaction which converts it into bio
gas and odourless water.
•The gaseous effluent (methane) is either
continuously let off to the atmosphere or can
be collected to be used for various energy
incentive activities like cooking water and
room heating.

Using the By-Products
• The water can be used as a
self sustaining irrigation
source.
• By adding a reed bed the
water can be recycled and used
further.
• Based on the usage of the bio
toilet, the methane produced can be
used to generate electricity and for
cooking purposes.
