Conventional municipal solid waste litter (MSWL) collection methods are labor-intensive, inefficient, and ineffective at separating waste from fine dust. Existing manual or basic vacuum systems lack automation, mobility, and energy efficiency, leading to poor performance and long collection times. A compact, mobile, and automated solution is urgently needed for efficient, real-time MSWL and dust collection with minimal human effort.
- Dual Collection Mechanism: This innovation enables simultaneous separation and storage of Municipal Solid Waste Litter (MSWL) and dust particulates in distinct filter bags.
- High Suction Performance: It achieves a velocity flow rate of 5,000 CFM at the nozzle inlet-superior to comparable existing technologies.
- Backward-Inclined Impeller Design: It enhances suction efficiency and reduces pressure losses.
- CAB Efficiency: The Centrifugal Air Blower (CAB) delivers 3000 m³/h inlet airflow with 70% overall performance efficiency at 2800 RPM.
- Real-time and Automated Operation: It enables minimal human intervention and automated litter collection across terrains.
- Modular and Mobile: The compact design is adaptable for mounting on mini-vans, trucks, and other vehicles.
- Manual Assist Option: Its flexible hose pipe with movable handle enables targeted cleaning in hard-to-reach areas.
- Energy Efficiency: It has stable power consumption (~1.57-1.67 kWh) across varying conditions, ensuring operational reliability.
- Time-Efficient: It is capable of collecting litter in 37 to 41 seconds per operation depending on hose type.
- Customizable Flow Rate: It is equipped with Variable Frequency Drive (VFD) for adjusting suction power based on waste density and type.
The prototype consists of a compact, mobile unit assembly (MUA) designed for efficient municipal solid waste litter (MSWL) collection. It integrates a centrifugal air blower (CAB) mounted on top of a collection chamber (CC), with backward- inclined impeller blades rotating at over 2800 rpm to generate high suction power. The unit features a flexible suction hose pipe with a manual handle for targeted waste collection and a nozzle inlet offering a high airflow velocity of 5,000 CFM. Dust and litter are separated using horizontally oriented filter bags at the back end, supported by a filter mesh and duct system. The assembly is powered by an induction motor connected to a portable generator, with optional integration of a variable frequency drive (VFD) for adaptive suction control based on waste type and density.
The patented technology has proven feasible in real-world urban settings through batch and pilot-scale evaluations, showing clear operational and economic advantages over conventional methods. A comprehensive techno-economic assessment confirmed its financial viability. Future upgrades will integrate sensor-based automation and data-driven monitoring to boost efficiency, reduce human intervention, and support scalable, smart city waste management solutions.
