Preparing for rainy days: DOST, DENR turns over garbage collecting tech to Malabon
By Dhel Nazario
As part of the government's solid-waste management and flood control efforts, the Department of Science and Technology (DOST) together with the Department of Environment and Natural Resources (DENR) has turned over the Automatic Trash Rake (ATR) technology to the City of Malabon.

In a statement, DOST said that the initiative will complement the city’s solid waste management program to rid its constituents of floods and garbage. This technology is one DOST and DENR's solutions to a national battle against garbage and flood.
Perennial floods caused by clogged drainage and sewerage lines have been the bane of every Metro Manila resident’s existence as the problem seems to worsen every year in the absence of an integrated program to curb the urban waste problem.
The ATR was developed by DOST-Metals Industry Research and Development Center. It runs on a 10-horsepower diesel engine with six sets of rakes with a total width of six meters. To fully address the waste disposal and collection problem in other areas, there are now plans for more ATR installations in the coming years as DENR is already wrapping up the details for two more locations in Metro Manila.
The ATR is installed at the Letre Creek in P. Aquino Ave. and is strategically positioned to collect about 43.5 cubic meters (cu/m_ of garbage in a month and five cu/m in an eight-hour operation. Initial runs posted 1.45 cu/m of trash were collected in a two-hour operation. The city personnel are now gearing up for the onslaught of heavy rains brought about by monsoon season as garbage from the nearby cities will swarm the river system leading to minor tributaries.
According to DOST, the project was conceived in 2018 after several consultations with various local government units (LGUs) in the CAMANAVA area which consists of Caloocan, Malabon, Navotas, and Valenzuela. DOST said that historically, the area has been frequently inundated by heavy rains coupled with the rise in sea level and overflow of rivers and dams thus leaving low-lying and flat terrain areas submerged in water.
The Malabon-Navotas-Tullahan-Tinajeros, a major river system that connects to the Letre creek where Malabon ends up swamped with tons of garbage annually.
In Malabon alone, about seven to eight tons of residual waste are collected every month, a number that has been improved lately as the city turned to an effective waste segregation and recycling program. The said initiative is implemented in collaboration with a non-government organization to entice residents in helping the government manage its solid waste.
"In previous years, about .56 kilograms per capita of the 400,000 Malabon residents contributed to its garbage woes," DOST said.
During the ceremony, de la Peña told LGUs and other stakeholders to lay down the framework for using waste to convert it into energy. He expounded that the technology is already there saying, “we lack the policy on how we can implement this.” The DOST-developed technology will help the city in its solid waste management program, particularly its collection of floating garbage from the Letre Creek to stop it from reaching its neighboring LGUs. This, in turn, hopes to augment the flood control efforts as it will minimize garbage and floodwater spillovers from entering the rest of Metro Manila.
