Kitchen waste carbonizer

KEY PROBLEMS

• Kitchen waste are generated from domestic, hotels dan restaurants

• Estimated 1kg/capita• Disposed in landfills• Causes landfill saturation, decomposition causes

leachate, odor • Consist of high organic content that are source of

energy but currently wasted• Consist of high moisture content easily decompose

SOLUTIONS

• Convert the waste into energy source• The kitchen waste is carbonized, ground and

briquetted to form solid fuel that has commercial value or used as fuel for cooking, barbequeing, hot water production, boiler fuel.

Novelty and Inventiveness

• There is no such similar equipment in the market to deal with kitchen waste and carbonized it.

• The problem with enormous amount of kitchen waste generated poses a problem it its disposal and utilization.

• This unit is designed to process all type of organic waste materials with high moisture content (MC) such as kitchen wastes, agricultural wastes, etc. without any prior drying process.

• These waste materials are transformed into a valuable end product of carbon that can be used as a high grade smokeless fuel for cooking and domestic heating, and also as a fertilizer for plants.

• All gases produced from the system are cleaned using a gas cooler to condense the water; water/oil scrubber to remove the tar; and a charcoal filter to further remove any gas impurities.

• After the process, carbonization reactor can be cooled quickly using a water sprayer, thus saving processing time.

• With a compact design, this system can save the space of installation. It is mounted on wheeled frame so that it can be moved easily.

• The system is very simple to operate by simply pushing buttons on the control panel

Applicability of The Invention/Innovation

• There are a lot of wastes generated from hotels, restaurant, hostels, canteens etc. These wastes are merely discard and thrown away into the garbage bag and disposed in landfills.

• It may not seem to pose any problem at present and hence no effort was done to utilize these wastes. Composting has been done in various places to utilize the kitchen waste into fertilizer. The process takes a very long time and accompanies with extreme and unpleasant odor that may attract vermin.

Status of Inventition/Innovation

• The invention is complete and ready for commercialization.– Capacity : 20 kg – Material : Kitchen waste (Organic/Degradable) – Heating : 24 kW (Heating system: Heater

band) – Process time : 4 hours – Operating temperature : 400oC– Electrical consumption : 96 kWh

Commercialibility and Market Potential

• The initial request came from a local company who was contacted by a company in India to carbonize kitchen waste for restaurants.

• The company will assist in marketing and selling the equipment locally and abroad.

• Potential customers will be:– Hotel operators– Restaurants operators– Student hostels– School canteens– Cafeteria

Collaboration

• The local company is Ultra Energy Resoruces Sdn Bhd in Kulim. The company has since become a collaborator and several projects including a KTP project on Waste conversion to fuel via torrefaction process in 2012

Knowledge Management• Research and experience on carbonization of various organics waste particularly

agricultural waste have been done successful. This knowledge is now utilized to addresses the above issues.

• Several projects have been done using the pyrolysis technology to convert organic waste into carbonized material.– Khor Kwan Hooi, Zainal Alimuddin Zainal Alauddin, Lim Koon Ong, Laboratory-Scale Pyrolysis

Knowledge Management

• Knowledge transfer is one the key importance in collaboration with industries. Ultra Energy Resources has gained substantially in the previous KTP project.

• Restaurant, Hotels, Domestic, Schools, Hostels, etc.

• Solid fuel production: grinding and briquetting• Source of income from sales of solid fuel.

Intellectual Property (must provide any supporting documents)

• Patent application has been submitted.

IMPACT OF THE PRODUCT

• Reduce the life of the landfill• Provide alternative source of energy • Provide source of income.

Environmental friendliness

• The machine manages the waste generated from the kitchen that would normally be dumped at the land field and causes significant environmental and health problem
