ELECTRICITY GENERATION FROM BIOGAS
Biogas technology is the generation of a combustible gas from anaerobic biomass digestion. There are millions of biogas plants in operation throughout the world. Whereas using the gas for direct combustion in household stoves or gas lamps is common, producing electricity from biogas is still relatively rare in most developing countries. In Germany and other industrialized countries, conversion of biogas to electricity has become a standard technology. The biogas yield of a plant depends not only on the type of feedstock, but also on the plant design, fermentation temperature and retention time. Maize silage for example, a common feedstock in Germany, yields about 8 times more biogas per ton than cow manure.

Biogas is used as fuel for combustion engines, which convert it to mechanical energy, powering an electric generator to produce electricity. Appropriate electric generators are available in virtually all countries and in all sizes. The technology is well known and maintenance is simple.

This event complements another initiative by Burhani Foundation (India) known as the Reforesta-tion and Environmental Study Drive which aims to resuscitate once thriving eco-systems such as Rajmachi in the western ghats; to restore them to their former state and to spark interest of young minds towards nature conservation.
To celebrate World Sparrow Day, Burhani Foundation (India) distributed bird feeders to those residing near Mithi River and Versova Beach. The activity was done in partnership with Adv. Afroz Shah as a way of supplementing the ongoing ‘Turning the Tide’ initiative with a more diverse and comprehensive approach to conservation and environmental responsibility. Community members and school children also participated in the event.
World Sparrow Day—20th March 2019
The initiative is inspired by the teachings of Islam and various prophetic traditions which instruct Muslims to be mindful not only of the environment in which they live, but also consider and care for the various creatures which inhabit it along with us.
During the 100th birthday celebra-tions of His Holiness Dr. Syedna Mohammed Burhanuddin RA in March 2011, BFI set a Guinness World Record by distributing 52,000 bird feeders in an attempt to save the Sparrow.
The current activity aims to take the initiative further and create much needed awareness about the steadily decreasing number of sparrows the world over.

In the warmer months, it can be tempting to blast the air conditioner in an effort to
stay cool. But there is a much cheaper, more environmentally friendly way to keep
the temperature down in your house: plants. Plants lose water during transpiration,
which cools the air around the plants, leaving it purified and fresh. If you're looking
for a natural, inexpensive way to keep your house cool, consider getting one of these
five plants, which can help keep temperatures down.
5 Plants To Help Keep Your House Naturally Cool
1. Aloe Vera
Having an aloe vera plant on hand will not only come
in handy if you get any nasty sunburns, but it is also
effective at cooling the air temperature and removing
formaldehyde from the air.
2. Areca Palm Tree
One of the most popular living room plants is the areca palm
tree, a decorative house plant that acts as a natural
humidifier. In addition to cooling off your home, the areca
palm can remove benzene, formaldehyde & trichloroethylene
from the air.
3. Ficus Tree
The Ficus tree, also known as a weeping fig,
helps to keep the air temperature cool as well as
reduce air pollution and improve air quality.
4. Fern
This plant helps to not only cool and humidify the air, but
like aloe vera, it is good for cleaning formaldehyde out of
the air. In fact, scientists at NASA say the fern is one of
the most effective air-purifying plants.
5. Golden Pothos
The golden pothos is a great plant for those who aren’t exactly
garden-savvy, as it’s extremely easy to take care of. It requires
little light and little care, and it will keep your air cool as well as
purified.
