At time when India's capital Delhi is struggling to get away with tag of World's most polluted city, the country has got its first Bio-Methane bus that runs on "food waste". Yeah! -- you heard that right -- the bus that runs on food waste or technically called as bio-methane gas which is produced out of bio-degradable materials like food/ kitchen waste.

The bio-methane bus was designed & made by home-grown automaking company - Tata Motors. The company has designed and developed bio-Methane engines for Light Commercial Vehicles (LCV), ICV, and MCV buses and the powertrain options include - 5.7 SGI and 3.8 SGI. The new bio-methane engines were introduced at the Bio-energy programme, called 'Urja Utsav,' and the Tata LPO 1613 bus, which features the top-spec 5.7 SGI NA BS-IV IOBD-II engine that makes 123 bhp and develops 405 Nm of peak torque, was also showcased at the event.

Tata Motors believes that moving towards bio-Methane will not only contribute majorly towards decreasing emissions for a cleaner environment but also help promote the Government of India's Smart City initiative. Interestingly, the bio-methane powered Tata LPO 1613 showcased at the event is already in operation by PMPML (Pune Mahanagar Parivahan Mahamandal Limited) in Pune city.

Bio-Methane Bus India

Notably, a bio-methane bus that runs on food waste is said to be more efficient than a normal CNG bus for the simple fact that in case of the latter, heavier hydrocarbons also co-exist with the Methane gas while Bio-Methance engines has only Methane in it. Furthermore, this makes Bio CNG more application friendly and efficient than regular CNG.

Speaking on the Bio-methane bus development, Mr. Rajendra Petkar, Head of Power System, Engineering, Tata Motors, "The showcase of the Bio-Methane bus is a step towards developing environment friendly vehicles. Bio-methane is produced out of bio-degradable materials like kitchen waste. This gas, which gets produced out of natural degradation process, escapes into the atmosphere unused. However, if this is trapped and used in engines, it reduces the net impact on environment and at the same time produces useful power."

Tata Motors has, in the past, introduced technologies in CNG engines like long life spark plugs, sequential gas injection technology, plug type coils, skip fire and longer oil drain intervals.
