The Dangwa Flower Market which is rightfully known as the Bulaklakan ng Maynila is
known for its beautiful streets filled with a colorful array of flowers. But due to the high amount
of flower being processed daily, an excessive amount of waste such as stems, leaves, and
discarded petals are produced which are commonly spread throughout the market before their
disposal done by the Department of Public Safety (DPS) of Manila. This study is a
multidisciplinary approach in the reduction of the volume of organic waste at the Dangwa
Flower Market.
This paper features a machine capable of shredding organic waste and subsequently
compacting it, further decreasing its volume, to aid the waste problem at the Dangwa Flower
Market as well as increase the total amount of waste collected by the DPS. The machine is
composed of mechanical elements used in volume reduction; a shredder with two feeding
rollers and a horizontal blade assembly; a compactor; and a cabinet style canister where the
shredded organic waste will be compacted.
This machine’s shredder is capable of reducing the volume of organic waste by up to
36.01% and has a throughput capacity of 2.0745 kg/min. Meanwhile, the compactor was able
to reduce the volume of shredded organic waste by 64.408%. In addition, the shredder and
compactor assembly were able to successfully reduce 50% of the original shredded waste put
inside the canister.
