Project Name: Management of Kitchen Waste of Hotels and Restaurants
Project Theme: Industry
Title: Decomposition of biodegradable and non biodegradable things of hotels and restaurants
Objective: To dispose off and utilization of materials like cooked food, uncooked food and plastic containers and packings of restaurants and hotels by converting them into manure and fuel respectively.
Scientific principle: The biodegradable garden waste cooked food and uncooked food of hotels and restaurants are converted into manure and manure tea with the help of vermin composting (biological catalyst) and thermal decomposition
The plastic waste such as plastic cans, pvc etc generated by hotels and restaurants containing petroleum plasticizers are converted into fuel by simply heating them and then condensing the vapors to form liquid which can be used for multiple purposes.
To convert plastic waste into fuel we require –burner, conical flask, test tube and test tube holder, cock, bent tube and plastic pieces.
Working: When we heat plastic (pvc) in non oxygen environment it will melt not burn after it is melted it will start to boil and evaporate vapors of hydrogen chloride will be formed. Those vapors are to be passed through a pipe and when cooled vapor will condense to form liquid .while some vapors with shorter hydrogen chloride length will remain as gas. This makes a liquid fuel that can be used for multiple purposes and gas (hydrogen chloride) also has number of uses such asproduction of HCL, production of detergent and cleaners and hydrogen chlorination of rubber etc.
Material Used: For converting biodegradable waste such as cooked food and uncooked food into manure and manure tea we require – 3 containers carrying garden waste , cooked food , manure and manure tea respectively other than that we require citric acid , water burner , red worm, cloth , sunlight and connecting pipes.
Working: first of all, the biodegradable waste such as cooked food, uncooked food is collected in acontainer. Then the other biodegradable materials such as mud, grass and soil is added. Some holes are made in the container as the decomposition of food requires oxygen and red worms are also used as they act as biological catalyst. The food gets converted into manure. The manure is kept in a sack and the sack is kept in water. The nutrition from manure gets transferred to water. Which is being named as manure tea. The process does not lowers the nutritional level of manure similarly the manure tea can also be diluted which again does not lowers its nutrients.
Utility and future scope: The benefit of using cooked food, uncooked food and other biodegradable waste as compost material include reduction of overall waste and provide raw material and finished fertilizers. The benefit of using plastic for production of fuel gives results such asconservation of non renewable of fossil fuels, reducing the consumption of energy used , reducing the amount of solid waste going to landfills , reducing the emissions of harmful gas like carbon dioxide into the atmosphere.
A campaign has also been started in our school under which, according to our model we are collecting the waste foil papers and bits of thrown food which gets accumulated in the school ground after the recess. The waste is being stored in separate containers and is being converted into non-refined petroleum and manure.
Name of the School: Sri Aurobindo School of Integral Education, Sector-27A, Chandigarh.
