[D] TO DEVELOP A COST-EFFECTIVE AND EFFICIENT ON-SITE NON-DOMESTIC MIXED WASTE TREATMENT SYSTEM

Non-domestic waste is collected by licensed general waste collectors (GWCs) and treated at licensed waste disposal facilities. While premises segregates recyclables from their wastes to be recycled by the main waste management contractor, there are still significant amount of general waste collected by GWCs and sent to incineration plant and then to landfill. Examples of such general waste could be food wastes mixed with paper, plastic, packaging and potential metals which reduces the “recyclability” of the individual waste streams.

Currently, the only type of waste treatment installed at facility level is on-site food waste treatment machines. However, as they are used to treat source segregated food waste, general waste are currently being collected by GWCs for incineration.

As general wastes is made up of different types of wastes, the challenge is to look for a versatile system to effectively and efficiently (such as a self-sustaining system where power output is higher than input. Efficiency for hot water could be measured in terms of cost savings from conventional hot water generation) treat the general waste to higher value by-product such as electricity, hot water, etc.

Another key challenge is to propose a system which can function within the waste management facility in existing premises, such as bin centres.

The proposed solution should meet the following requirements:

1. There should be minimal noise from the proposed system operation 
2. (a) The proposed system will need to fit into the existing premises’ waste facilities or in spaces of proximity.Note: As different premises generates varying amount of general waste, proposals should include the recommended treatment capacity up to 35 tonnes of general wastes/day. Depending on the recommended treatment capacity, shortlisted companies will be invited for a site survey and are expected to refine their proposals according to the site-specific environment.(b) The total power consumption of equipment(s) used must be within total allowable power supply in the premises to prevent power trips. QP/LEW is to certify the installation of the system is safe for the purpose of the trial. (c) The general waste profile comprises food waste, paper, plastic and packaging waste. Thus, the system should be a versatile system to effectively and efficiently treat the general waste. 
3. The proposed system must not cause any public health issues and comply with the EPHA and its relevant subsidiary legislation. 
4. The proposed system must comply with the necessary building regulation requirement. 
5. The operation of the system should be efficient (e.g. cost efficient, energy efficient) and manpower should also be efficient.

An on-site waste treatment system within existing premises’ waste management facility to effectively treat their own general wastes.

A versatile system to effectively and efficiently treat the general waste (made up of different types of waste streams) to higher value by-product such as electricity, hot water, etc.

The target milestones are:

1. Completion of site evaluation, equipment concept design & detailed drawings 3 months from start of project 
2. Necessary regulatory approval 6 months after the start of project  
3. Completion of working prototype ready for evaluation 8 months after the start of project 
4. Trial of working prototype with solution adopter for 3 months 
5. Provide reports and findings on data collated during trial 
6. Completion of full functional end product ready for pilot deployment 15 months after the start of project
