Waste sorting plants (MRF)
Household waste sorting and recycling is an ever more pressing need.
Mankind produces hundreds millions of tons of waste that includes a significant number of materials suitable for re-use and therefore having high market value.
Such materials are recovered by waste sorting plants (WSP) or Material Recovery Facilities (MRF) produced by EcoMechanics.
Scale, capacity, and automation level of waste sorting plants can vary widely. We help our clients find the best solution available for each specific conditions. Our goal is to make this activity profitable and long-term for each customer.
Quantity of solid household waste (SHW) handled by the sorting plant determines the capacity requirements. In the minimum configuration, the sorting plant has only two conveyors - feed and sorting:
Figure 1. Diagram of a WSP with two conveyors (minimum configuration).
Number of stations (stand-points) along the sorting conveyor is from 5 to 12. One station is usually occupied by 2-4 workers placed opposite each other on different sides of the conveyor belt and picking same useful fractions (e.g. PET bottles) from the waste flow moving along the conveyor. Number of stations depends on the capacity requirements and suggested range of useful fractions of SHW to be sorted from garbage flow.
The level of automation of the sorting plant is determined on a case-to-case basis and depends on many factors, not only on the financial resources available to the customer.
Any decision on the automation level requires a comprehensive study of such conditions as the availability and cost of labor, availability of qualified personnel to maintain complex technology, dimensions of the waste sorting plant site, power supply limitations, etc.
Ability to invest considerably in a highly automated sorting plant does not always mean that this option is economically feasible. In most cases, the best economic effect is achieved by a reasonable combination of automation and manual labor.
In cases where the plan is to sort a significant quantity of SHW (more than 200,000 tons per year), a higher level of automation is preferable.
Actual sorting of SHW (recovery of useful fractions) is in most cases a manual operation.
Automation is required to prepare the waste for manual sorting. Such preparation can significantly increase productivity of manual sorting and requires installation of following equipment:
-
Bag opener (as we usually pack our SHW in plastic bags).
-
Screen to screen fines, mostly organics.
-
3. Separator to divide the feed into homogeneous flows liberated from the fine fractions.
Automation is also used in the compression of sorted useful fractions and tailings left after the sorting. In this case, automatic horizontal presses are used instead of conventional vertical presses.
For handling and feeding the material into the press, additional conveyors and moving floor systems are required.
Below is an example of a 200, 000 tons per year waste sorting plant:

Being a part of EcoTechnologies group which is busy in all stages of waste management and recycling process we know exactly what is required for successful sorting. We are ready to work with you to choose the optimal configuration of the waste sorting plant that best suits your conditions and resources.
