Very frequently people just throw away their 'Old' or 'out-dated' or faulty Personal Desktop Computers with no intention of sending for repair or upgrading due to the hassle of transporting the PC and the high cost of repair and upgrading. Many of these 'Old' or faulty PCs landed in the rubbish dump waiting for the Scrap-Metal man to come and salvage the metal parts to be melted down and recycled, not realising that some of the other devices may still be in working condition and can be salvaged and recycled too. This project looked at how old PC's Power Supply, CD-ROM drive, active speakers can be salvaged and converted into a Mini-Compact Disk player of reasonable sound quality for audio entertainment at home.

With this project, money can be saved from buying a new Mini-CD player audio system. The raw materials for the production of these equipments can be saved and reduced because they can be recycled. There will be an overall savings in terms of lower cost of raw material production, procurement and consumption in the electronics and steel industries.

We may in our small little ways help to minimise the waste disposal problem as this is a big global problem and was highlighted in "THE STRAITS TIMES" papers on the Friday, June 20, 2003.

Used metallic drink cans can be sold for recycling purposes, thus it is worth the while to sort out the cans from other trash. This sorting process can be tedious and Smart Bin can be the solution. Smart Bin is "smart" to sort out metallic cans and non-metallic, for instance plastic bottles.

Besides, the Smart Bin can displace the sorted items into separate containers, which are removable and items can be recycled. This prototype can also be used as an educational tool to promote a clean and green environment amongst our young in an entertaining and fun way. On a bigger scale, Smart Bins can be placed in food courts to inculcate the good habit of recycling.

The common refuse chutes in HDB flats are compartmentalized into food wastes and recycling wastes, each of which is connected through underground pipes to the CMWPS through underground pipes, are built in wet markets, shopping centers and food centers. A weight sensitive compartment is built to store all recyclable materials such as papers and cans in schools. A sensor will be activated in CMWPS when the compartment reached a specified weight, and private collectors will be deployed to collect the waste from the schools.

Additionally, the team also proposed a web portal to be set up to provide environmental statistics and information on each particular estate. The portal also serves as the communication hub for buyers and sellers of recyclable wastes and the by-products of composing organic wastes.

Our lifestyles and needs have changed tremendously over the years and as we enters into the new millennium. These changes have also led to the development of revolutionary ideas to meet the needs of our changing lifestyles. For instance, home concepts. In the near future, homes will be combination of shopping mall, school, workplace and houses and other facilities.

Although similar "one-stop" home concept has been introduced in Singapore, they are unconsciously depleting the earth of its precious non-renewable resources. Hence, this project proposed the design of an intelligent estate that would suit the Singaporean families' lifestyle and needs in 15-20 years time, without causing unnecessary harm to our environment.
