Delivering Sustainable Environmental Solutions

Our subsidiary STSE Engineering Services Pte Ltd provides solutions and services for water and solid waste management by drawing on our engineering capabilities and deep technical knowledge in environmental technology. Work that we carry out include waste logistics, waste treatment, waste-to-energy, mechanical biological treatment, water and wastewater treatment, and renewable energy solutions. We provide these services in a variety of contracting models, including engineering services, Engineering Procurement & Construction (EPC) contract, Operations & Maintenance (O&M) contract, and Design-Build-Own-Operate (DBOO) schemes as well.

STSE Engineering also specialises in renewable energy solutions and Eco Park planning services. Harnessing natural renewable energy for such projects, we work in tandem with project management personnel to meet customer requirements and local conditions.

Using our engineering expertise and experience, STSE Engineering offers total packages to meet customers’ environmental engineering needs. We provide consultancy, design, construction and operation and maintenance programmes and turnkey solutions.

Together with our wholly-owned subsidiary companies in China and Brunei, STSE Engineering has successfully executed several projects in Singapore, China, Brunei, Middle East, India and South East Asia.

Capabilities

  • Water - Water Treatment

  • Water - Wastewater Treatment

  • Waste Logistic - CleanVAC PWCS

    Our centralised and automated waste management solution is used for high rise buildings, mixed developments, recreational parks and hospitals to efficiently and cleanly remove waste materials for a cleaner environment. Flexible and scalable to individual buildings or even entire townships, it relies on an intricately designed network to reduce pollution. It connects to either indoor or outdoor drop-off points for the disposal of the waste materials. As a configurable system, it is used by various customers, such as Hotel Phoenix in Singapore and Tianjin in China.

  • Waste Logistic - Refuse Transfer Station (RTS)

    This solution forms an integral part of waste management, as it provides customers an efficient way to transfer waste to landfills away from city centres. Comprehensive built-in odour and dust control system help minimise environmental pollution, while a customised system tailored to customers’ requirements results in improved results. Customers can also simulate the impact of the system to have an idea of the system’s impact before implementation.

  • Waste Treatment - Material Recovery Facility (MRF)

    Using sophisticated technologies to sort out a city’s waste, ST Marine is able to enable further material separation, according to customers’ requirements. For example, lightweight packaging from bags, bins and containers can be filtered into the individual fractions (or mono-fractions bales of tinplate, aluminium, composites and plastics). We also customise our products for tough-to-solve applications, from design to start-up. We are proud to have designed and built the MRF project in Beijing Daxing in China.

  • Waste Treatment - Mechanical Biological Treatment (MBT)

    MBT is a type of waste processing facility that combines a segregation facility with biological treatment under aerobic and/ or anaerobic conditions. MBT facilities can be designed to process municipal solid waste as well as commercial and industrial waste.

    MBT facilities enable the recovery of materials contained within commingled waste and facilitate the stabilisation of the biodegradable portion of the waste. Like in a materials recovery facility (MRF), the MBT mechanically breaks down the waste into smaller parts and recover a portion of the recyclable waste.

    At the same time, micro-organisms that are either aerobic or anaerobic help break down the biodegradable component of the waste. This yields usable by-products such as biogas and compost. The biogas can generate electricity and heat while the compost can be used as a soil improver.

    The overall process is designed with functionality, cost-efficiency, easy maintenance, safety and environmental friendliness in mind. In addition, with its largely automated operations, minimum manpower is required.

  • Waste Treatment - Waste-to-Energy (WTE)

    Waste-To-Energy (WtE) incineration is an environmentally friendly incineration process that minimises the emission of pollutants into the air.

    WtE incineration eliminates over 96 per cent of waste, including sewage sludge, medical waste and bio-hazardous materials. Fitted with advanced flue gas cleaners, a WtE incinerator’s emissions are smoke-free, odourless and practically free of pollutants.

    In collaboration with our consortium of leading industry partners, STSE provides a comprehensive range of WtE treatment services, ranging from design consultancy and environmental impact assessment to maintenance, repair and overhaul programmes.

    Our WtE systems feature long service life, high throughput performance and efficient electrical consumption, enabling our customers to save costs and adopt environmentally responsible practices.

  • Landfill Management & Rehabilitation

  • Renewable Energy

    ST Marine is capable of delivering a wide range of renewable energy solutions, including wind energy, solar energy and hydro energy projects. Our services include engineering, procurement and construction (EPC) and  design, build own and operate (DBOO) of renewable energy projects.

  • Projects - NEWater Factory

  • Projects - Brunei Integrated Waste Management System

    In July 2010, ST Marine was awarded a contract with our Brunei partner to design and construct a new “engineered landfill” and waste transfer & logistics station, as well as three years of operations and maintenance.

    Located at Sungai Paku, the landfill was constructed to the highest US EPA standards, covering an area of approximately 110 hectares. Designed as a modern landfill, it made use of leachate and landfill gas management. Onsite monitoring facilities regularly carried out landfill gas analysis to prevent buildup and emission of Volatile Organic Compounds (VOCs).

    Delivering the initial project phases 6 months early and providing flexible interim extensions at the end of the Operate & Maintenance (O&M) obligations to the Brunei government – these are proven situations of how STSE Engineering would place their customer’s needs first, through its dedication to success and through-life support.

    Implementing the best and most suitable of each technology for transfer station, engineered landfill and wastewater treatment, STSE Engineering had helped create an integrated, environmentally responsible and energy-efficient model of solid waste management for the country meeting stringent US EPA standards for engineered sanitary landfill waste disposal.
