NSL's R&D team together with National University of Singapore and the Land Transport Authority developed an environmentally-friendly low noise asphalt concrete design for roads in Singapore using steel slag aggregates, a by-product from the steel manufacturing process.

This is a sustainable business initiative as it reduces the landfill needs and at the same time converts slag into a renewable resource for the country.

NSL's R&D department developed various green concrete materials from recyclable materials which was recognised and certified by the Singapore Environment Council's Green Labelling Scheme.

In 2017, the Precast & PBU division gained greater recognition for its efforts in promoting the development of environmentally sustainable buildings. The precast components of its Singapore and Malaysia operations were awarded the prestigious Singapore Green Building Product certification for 45 types of environmentally-friendly concrete mix in June 2017 and another 35 types in January 2018 respectively.

Eastern Pretech continues to offer 45 designs of green concrete mix to support sustainable construction in Singapore, and 35 types in Malaysia. The demand for green concrete continues to increase, now making up about a third of the volume of concrete projects in both countries. In 2018, 30% of the total projects volume are made from green concrete mix.

During the same year, NSL’s R&D department together with its Singapore Precast business developed a lightweight concrete for its PBU system. The new PBU product which weighs about 40% lighter received a certificate of In-Principle Acceptances from the Building and Construction Authority, enabling it to broaden its PBU offerings.



In addition to our business and products, NSL Group is also a supporter of environmental groups and activities.

NSL organised the inaugural electronic-waste (e-waste) recycling campaign for its companies in Singapore in 2017. During the week, some 1,119kg of e-waste collected from staff and various departments was either recycled or disposed of appropriately.

Its subsidiary in property business, Raffles Marina Club, sponsors the Planetary Coral Reef Foundation (PCRF) through a charity regatta. Funds were raised for the Foundation to finance its marine conservation projects across Southeast Asia.

Since 2004, NSL has been participating in NEA's Environmental Challenge for Schools (ECS). NSL has adopted Clementi Primary School for the programme from 2007 to date.

On top of financial support, NSL works closely with the primary school students on projects such as recycling campaign and energy conservation activities. NSL aims to educate and inspire the younger generation by supporting causes that advocates sustainability of the environment such as recycling campaigns, water and electricity conservation initiatives as well as increasing awareness on the importance of protecting the environment and nature. 

In 2017, NSL and the school conceptualise a wall mural that encourages students to care for the ocean. The colourful mural displays five ways to save marine life, providing a meaningful facelift for the school’s ‘recycling corner’.

In October 2018, 19 representatives from NSL OilChem Waste Management volunteered for Project SeedLinks at Yangzheng Primary School. With guidance from Primary Five student buddies, 127 preschoolers from My First Skool, PCF Sparkletots and Bethesda Kindergarten were given an opportunity to grow their own seedlings using recycled seed holders. Besides nurturing the young to care for the environment, this programme also aims to contribute to a sustainable environment for our future generations.
