3. Background & motivation

4. Facts about wastes
2 billion tonnes of wastes generated every year globally.
In SG, Waste is generally collected thrice a week by agencies.
Solid waste management and recycling techniques are employed to deal with the wastes and requires support from the customers to improve efficiency.
Reference : National Government Agency, Singapore & Waste Atlas TM

5. motivation 12% of food waste is only recycled.
85% of waste is disposed and there is a huge potential for further enhancements.
Developing an incrementally integrated system for food waste management

6. Observations & understanding of the problems

7. Inefficient Disposal of Waste
Here’s the problem
Inefficient Disposal of Waste

8. Present technology & products

9. The need for a new system
Why?
What can be done?
Trash bins are not used to their full capacity.
Processing of wastes becomes cumbersome
No information on level of waste, lack of multi-functionality
Indoor composting is impractical
Can it stored/processed differently?
What are the bottlenecks in post processing?
Is it possible to provide information to the user and incorporate additional functionality?
Aerobic/Anaerobic composting

10. Objectives & deliverables

11. Proposed objectives
The system aims to improve the feasibility of reuse and recycle of wastes.
The system aims to reduce the time for collection of wastes.
The system aims to infuse a sense of pride in contributing to the green movement
Bin for Collecting waste
Fertilizer Production
Stage I
Biogas Plant Setup
Stage II
Biogas plant for HDB’s
Stage III

12. The Proposal
To develop a bin, process waste and setup an in-house waste management setup for HDB’s.
The system aims to have a method to ensure that the bins are used to their full capacity.
The system aims to have detachable parts to ensure multi- functionality.
The system aims to have a method to indicate the level of waste to the user.
The system aims to have a method to switch between automation/manual operation.
The system aims to have a method to inform the agency if the bin needs to be emptied.

13. Economic analysis
Possible earnings from fertilizers – SGD 120* per household per year – Stage I
Possible energy saving of 11%** per household in a year and energy production up to 850** KWh/yr/household.
Payback period for Bin would be around 1 year, as the proposed price of the bin is SGD 100***
Payback period for Biogas plant will depend upon no. of households and biogas production. If we have 250** households, the payback period will be around 1 years
Reference : * Based on 50% conversion efficiency ** Based on biogas production of 0.3m3/kg *** To be ascertained
