PGP House

It is common to notice that the fans and lights in kitchens are turned on from mid-night until next day morning. Some of the fans and lights may be turned on for 24/7. Such a scenario can be typical in all residences at PGP.

A ceiling fan operational for 10 hours daily will consume about 22.5 kWh electricity per month costing $4.55. Four 40 W fluorescent lights operational for 10 hours daily will consume 48 kWh per month costing $9.70. That will total to 70.5 kWh electricity consumption or $14.24 per month per kitchen (based on the tariff rate of 20.20 cents/kWh).

With over 40 kitchens in PGP House (and many more in PGPR), what could be done to avoid wasting electricity? What are the ways to manage such wastage in residences? Can we utilize frugal solutions to reduce electricity wastage?


It is said that about 790,000 tonnes of food waste was generated in 2014, equivalent to each person throwing away two bowls of food every . Unfortunately, only 13 percent of the food is recycled. Food waste at this scale not only creates the issue of running out of space in Semakau Landfill, but raises concerns regarding sustainability as the amount of natural resources left might not be enough to meet the growing needs of World’s population boom.

There are many government led initiatives to reduce food wastage in Singapore. For instance, National Environment Agency (NEA) has launched a campaign to reduce food waste in Singapore. NEA has also launched 2- year on-site food waste recycling pilot in two hawker centres.

While Singapore government has taken steps towards food waste management, as a social entrepreneur what can you do to minimize the food waste? What are some of your innovative solutions to create awareness and mitigate this compelling social issue? Can you envision frugal technologies that can reduce food wastage?


Imagine you are in a remote hospital in rural India, faced with rudimentary medical equipment to attend to patients. Each day many come to the hospital for treatment. Medical equipment is scarce the hospital operates on basic machines and processes, some of which are manual and prone to human errors and time consuming.

Many more in the remote villagers cannot make their way to seek medical care due to lack of infrastructure development and awareness. They are deprived of modern medical assistance. They suffer from various diseases like diarrhoea, typhoid, hepatitis, tuberculosis etc. due to impure drinking water, malnutrition, inadequate diet etc.

Medical teams roll out in trucks and vans to reach out to these villagers. They often visit schools to attend to the healthcare needs of young children and youths. Healthcare needs include advice on good nutrition, tracking and recording of physical development and dental care for the young and elderly. The hospital runs outreach programs to spread the word on health issues and to encourage good hygiene in the homes and the environment. They routinely screen for oral and cervical cancer, carries out obstetrics, dental, antenatal and malnutrition checks and adolescence screening.

The hospital operates on donations and is able to maintain an environment which is fully operational and comprehensive in its services. It is operated by a team of dedicated in-residence doctors and other supporting medical staff. Each week, specialists from nearby cities volunteer their time and services.

What other innovative solutions can you come up with to ensure right to health for all? What are some of the ways through which the above existing solutions can be made sustainable?
