## Issue

---

Hong Kong produces nearly three million cubic metres of effluent per day which is converted into 1 200 tonnes of [sewage sludge](/en/solutions/recovering-sewage-sludge "Recovering sewage sludge into green energy"). This volume will reach 2 000 tonnes per day in 2030. Until 2015, this sludge was either buried or released into the sea.

### The customer's objectives

• Provide a state-of-the-art, sustainable incineration technology solution to the massive and growing volume of sewage sludge.

• Raise public awareness on the environment.

## Veolia's solution

---

Design, build, and operate the world's largest wastewater treatment plant: T•PARK.

### Innovation

Fluidised bed incinerator technology reduces waste production by 90 % resulting in just 10 % being sent to landfills.

### Technologies

• Incineration: sludge inflow, fluidised bed incineration, and steam boilers.

• Treatment of gas emissions: DeNox to control nitrogen oxide emissions, dry reactor to reduce acid gases, multi-cyclone filter and pocket filter.

• Water treatment: Multiflo™, reverse osmosis.

• Wastewater treatment: flocculation, MBBR.

## Customer benefits

---

### Energy independence

T•PARK is 100 % energy independent with two 14 MW turbines that operate with steam produced during sludge incineration. When the plant is operating at full capacity, it produces nearly 2 MW of surplus electricity which is injected into the public grid.

### Comprehensive water management

T•PARK is 100 % self-sufficient in clean water - supplied by the on-site seawater desalination plant - and process water - rainwater collection and wastewater treatment to achieve ‘zero liquid discharge’.

### Waste recovery

T•PARK diverts 90 % of Hong Kong sewage sludge from landfills. The plant operates with the thermal energy produced during sludge incineration, which is recovered and converted into electricity.

### Innovative and ecological architecture

Symbol of the waste to energy journey and the city's green ambition, the T•PARK complex includes:

• an educational and recreational centre for the public with a 2 800 m2 interactive sludge treatment exhibit;

• a 9 800 m2 landscaped and ecological garden dedicated to restoring and preserving biodiversity;

• a theatre, an environmentally responsible café, a spa with three heated pools, and a rooftop terrace with breath-taking views of Deep Bay and Shenzhen.
