 II. Kerala shows the way
 BIOTECH has succeeded in tackling the problem of the dumping of food waste in 
the streets of Kerala through the installation of biogas plants that use the food 
waste to produce gas for cooking and, in some cases, electricity for lighting; the 
residue serves as fertiliser. To date BIOTECH has built and installed an 
impressive 12000 domestic plants (160 of which also use human waste to avoid 
contamination of ground water), 220 institutional plants and 17 municipal plants 
that use waste from markets to power generators. The disposal of food waste and 
the production of clean energy are not the only benefits of biotech's scheme. The 
plants also replace the equivalent of about 3.7 tonnes of LPG and diesel which in 
turn results in the saving of about 3700 tonnes/year of CO , with further savings 
2
from the reduction in methane production as a result of the uncontrolled 
decomposition of waste, and from the transport of LPG. BIOTECH won an Ashden 
Award for Sustainable Energy in 2007.
C.2.  Punctuate the passage given below
 what exactly is waste waste is anything discarded, rejected, or otherwise released 
into the environment in a manner that could have an impact on that environment 
how can we help we can help by practicing the three rs of waste management 
reduce reuse and recycle it has been estimated that every ton of recycled paper 
saves 17 trees 7000 gallons of water 4100 kilowatt hour of energy and three cubic 
yards of landfill space how does reduce and reuse help   reducing consumption is 
decreasing waste whereas the reuse of products such as recyclable plastics 
prevents the need for excess production of these exact same plastics hence the 
emission released from factories is lessened recycled products also take less 
energy to produce
