Use advice for data set
| When employing this data set for Life Cycle Assessment, ensure that the system boundary is correctly defined as starting from the point of wet sludge with a moisture content of 70%-75%, post mechanical compression and dewatering at the sewage treatment plant, to the end-of-life disposal. Emphasize the co-incineration process with garbage for energy recovery which should be accounted for in the energy balance and emissions calculations. Special attention should be paid to the allocation procedures between waste treatment and energy production when using this data. |
|
Technical purpose of product or process
| The municipal sludge treatment and disposal process described is primarily utilized for the management of wet sludge, with a moisture content between 70%-75%, originating from sewage treatment plants. The wet sludge is transported within the facility and co-incinerated with garbage to generate electricity. This process is intended for municipal waste management facilities, particularly those which practice co-incineration as a means to both manage waste sludge and produce energy. |
