Energy and Heat recovery credits for municipal incineration datasets

Written on: 27.06.2016#1




in my LCA-study i am using lots of datatset for the end of life like:

CH: treatment of waste plastic, mixture, municipal incineration ecoinvent

CH: treatment of waste polyvinylfluoride, municipal incineration ecoinvent


I would like to know if electricity and heat recovery is considered in this datasets?

At for this datasets the net energy production is mentioned.

Net energy production: 3.93MJ/kg electric energy and 7.66MJ/kg thermal energy

But it the produced energy credited in this dataset?

Or do I have to do this separatley ?

Maik B.

I would be interested to know more about that issue, too.

There are datasets that seem to include this, e.g. "treatment of waste plastic, mixture, municipal incineration with fly ash extraction | electricity, for reuse in municipal waste incineration only" and "electricity, from municipal waste incineration to generic market for electricity, medium voltage | electricity, medium voltage" (which is changing internally produced electricity into market electricity). But it remains unclear to me how this relates to the ordinary dataset were no electricity/heat is mentioned?

best, Maik

Hello Andreas and Maik, 

Did you ever get an aswer on this topic? I am also looking into this now.

 Dear Niklas, Andreas and Maik,


MSWI is producing energy but it used internally only. In reality there is a minor net amount of electricity produced from MSWI (respectively heat) but it has been chosen to model this as "burden free"."All burdens of waste incineration and subsequent processes are allocated to the function 'waste disposal'. Generated heat or electrical energy is free of any burden." This choice is very well documented and explained in the respective documentation: Doka G. (2003) Life Cycle Inventories of Waste Treatment Services. ecoinvent report No. 13. Swiss Centre for Life Cycle Inventories, St. Gallen, 2009.

I suggest you have a look in this file and more specifically in the chapter: 2.7 Allocation of energy production.
