Singapore Polytechnic

Established in 1954, Singapore Polytechnic (SP) is Singapore’s first polytechnic. It has 10 schools that offer 30 full-time diploma courses and three common entry programmes for close to 14,000 students. There are ten Business and Technology & Innovation Centres (TIC) collaborating with the industry to provide consultancy and deliver technological solutions.

The centres partner the industry to accelerate their growth with our expertise ranging from Advanced and Additive Manufacturing, Advanced Materials (BE), Building Information Modelling, Business Innovation, Consumer Chemicals, Data Science & Analytics, Energy and Chemicals, Food Manufacturing, Infocomm Technologies(5G & AIOT, Immersive Tech) and Advanced Maritime Safety Technologies.

Intelligent IoT Vertical Farming for Sustainable Singapore

The Intelligent IoT Vertical Farming system is 4-tiered and designed to be mobile, for either indoor or outdoor farming. It uses a hydroponic system that grows plants by enhancing the photosynthetic process. Since the system does not use soil, it is cleaner and more hygienic. FDA-approved and organic mineral nutrients are used for the hydroponic growing.

Compared to traditional agriculture, the vertical farming implementation saves more than 90 percent land area needed, while harvesting 80 percent more per unit area. Furthermore, with the water recycling design, the system achieves a reduction of 70 to 85 percent water usage. The set-up therefore, promotes the “Go Green” initiative and contributes towards Singapore’s effort to reduce our carbon footprint. In summary, we achieved:

> 90% land savings with > 80% physical spaces unlocked;
70-85% water savings; and reduced wastages of fertilizers and nutrients.

Ammonia Odour Free PdNi Alloy Deposition Solution

Conventional PdNi alloy deposition solution contains high amount of ammonia (> 50 ml/L) and ammonia salt as complexing agents in the formulations. As a strong alkali (pH> 7) and high volatile, pungent ammonia often evaporate fast at elevated temperatures and releases pungent ammonia odour, both of which is not user safe and environmentally friendly. It is difficult to maintain the pH in the chemical solution, and often affects the solution’s performance. Large amount of ammonia is often used to replenish this loss, and additional safety infrastructure is also needed for this process.

Conventional PdNi alloy deposition solution also requires high amount of palladium (25g/L) to achieve the desirable PdNi alloy (Pd80Ni20 in wt%) deposits at current density 80 ASD. The high amount of Pd increases the manufacturing cost as well as costs for disposal/recovery.

This technology offers an ammonia odour free PdNi alloy deposition solution by SP, with key features/advantages in:

  1. Reducing the use of ammonia and ammonia-based chemicals by replacing a portion of these key components in conventional solutions with other suitable complexing agents, resulting in ammonia odour free.
  2. Achieve the same PdNi alloy (Pd80Ni20 in wt%) deposits at current density 80 ASD with lower initial Pd concentrations, hence reducing palladium consumption, manufacturing and disposal cost.

Lixiviant for High & Selective Extraction of Silver from Silver-Coated Solid Wastes

Strongly corrosive acids and highly toxic cyanide-based solutions are currently the most commonly used lixiviants for extraction of silver from solid wastes through hydrometallurgy. While acids are generally able to achieve high extraction of silver, it is non-selective and leaches most of the other metals present, resulting in a complex mixture that needs rigorous segregation and purification downstream. Cyanide solutions are comparatively more selective towards silver but require costly safety infrastructure and measures to be put in place as they generate large amount of hazardous wastes.

The lixiviant developed offers a more user and environmentally friendly means to efficiently extract silver selectively from silver-coated solid waste. The formulation is free of cyanide and omits the use of any strong acids, making it relatively easy to handle and eliminates the safety, health and environmental problems associated with the use and post-treatment of conventional lixiviants.

The technology provider is seeking industry partners to test-bed the lixiviant and is open to license the technology to interested partners.

Bitterless Bitter Melon Ingredient

Bitter melon or bitter gourd is a vegetable used in Asian countries and it gets more bitter as it ripens. Studies have shown that bitter melon has many health benefits and one of them is lowering blood sugar. This is because bitter melon has properties that act like insulin, which helps bring glucose into the cells for energy. There are at least 32 active chemicals that have been identified that are responsible for its anti-diabetic and anti-cancer effects. Despite the claim of many health benefits brought about by the bitter melon, it is not widely consumed by the people due to its bitterness.

This technology provides a solution to mask the bitter taste of bitter melon, making it more palatable for consumption. In addition, this technology also protects the melon from environment factors leading to increased stability and longer shelf life.

Anhydrous Beauty: The Dry Water Based Skincare Formulation

Sustainability in beauty is increasingly becoming a priority across the globe. The green consumerism trend is driving more cosmetics companies to seek natural, clean and environmentally friendly ingredients, packaging and green products. This expectation is pushing beauty brands towards new sustainable innovations, such as waterless beauty, upcycling, carbon neutrality and reusable or refillable packaging solutions to meet the demands from the environmentally conscious generation. This has been further emphasized due to the current pandemic situation.

The technology aims to create a moisture-rich cosmetic in waterless form. This revolutionary concept enables personalization of formulations to produce moisture-rich powder that can be transformed into a spreading cream and/or serum easily upon application. The waterless formulation can be readily customised and adapted to suit the specific needs of an identified target market. Due to its waterless nature, the downstream packaging of products comprising this formulation will involve little use of plastics, thereby reducing carbon footprint.

Intelligent Lighting System

This technology offer presents an intelligent lighting system, which consists of the built-in motions sensors that is connected to a wireless controller. This technology provides light-on-demand (LOD) with dynamic adjustments in space according to the occupancy. Furthermore, LOD system can be used in dim areas with low traffics. These areas include multi-story car parks (MSCP), staircases and common corridors, etc. In addition, Intelligent Lighting System has been evaluated on MSCP and has produced with positive test-bed results.

Alternative Texturized Beverage in A Teabag for Health and Wellness Management

Bioactive compounds such as antioxidant used as functional ingredients in food and beverage has received much attention from food and beverage manufacturers. There are increased interests in health awareness and wellbeing from consumers, specifically the millennials, where clean and healthy lifestyle is seen as a priority.

Green Jelly Leaf, (botanically known as Cyclea barbata Miers) a medicinal plant native to South East Asian, is rich in antioxidant where flavonoids are the dominant active compounds. Flavonoids are part of polyphenol family and have various biological activities including anti-inflammatory, anti-cancer, and anti-viral properties. Analysis by HPLC-MS showed that Kaempferol 3-O-(6''-acetyl-galactoside) 7-O-rhamnoside and Theaflavin were the dominant flavonoids and contributed highly to jelly leaf antioxidant profiles.

This developed technology of a naturally occurring gelling beverage comprises of blended leaves which have the unique innate gelling ability when mixed with water. The jelly leaves powder is conveniently packed into a tea-bag and when steeped in tepid/hot water, the beverage would slowly thicken in water; providing a more texturized drink with smooth mouthfeel for the consumer.

Looking for partners who are interested to utilize this technology to innovate and develop beverages with alternative texture, e.g. Beverage Manufacturers, Food Industry.
