Technical Specification for 70-80kg/hour Medical Waste Management Equipment for Bangladesh Tender

System Overview

· Supply, Installation, Testing and Commissioning of Medical Waste Management Equipment using a non-burn thermal procedure by generating a combination of microwaves and steam.
· Treatment plant capacity requirement: including construction of associated infrastructure.
· Treatment method: Non-burn thermal technology (Microwave-based dry heat solution / Microwave plus steam combined, pressure-less hybrid process).

Core Thermal Technology

· Generate thermal energy directly within the waste mass through microwave interaction with internal moisture.
· Operate without steam injection, boiler, or external thermal carrier.
· Operate without vessel pressurisation.
· Does not rely on frictional heat, mechanical compression, or conductive heating as primary sterilisation mechanism.

Treatment Capacity (maximum 2 machines may be used to meet capacity)

· Load combined capacity (weight): 70-80 kg per hour or more (with density of 1L = 0.1 kg) – approximate
· Load combined capacity (volume): 700-800 L per hour or more (with density of 1L = 0.1 kg) – approximate

Types of Medical Waste That Can Be Processed

· Plastic materials and rigid boxes
· Glass materials
· Surgical instruments and materials
· Contaminated sharps
· Metals and syringes
· Hemodialysis wastes
· Liquid biohazardous waste
· Blood bags, urine bags, etc.
· Anatomical and pathological wastes (including placentas, etc.)

Treatment Performance Requirements

· Waste volume reduction: Approximately 80% or more
· Waste weight reduction: 20% or more
