WRATE V4 will run on a Windows 7, Windows 10 or Windows XP platform and is designed and licenced on an annual single user basis. The model comes with over 150 default waste management processes (ranging from complex combined heat and power facilities, landfills, different vehicles, and many recycling options).
The model options available are: Demonstration, Version 4 (V4) and Academic. The Table sets out the key differences between the versions of the software. When initially installed the software will be in Demonstration mode – which allows you to evaluate the software and to ensure that it will work on your system prior to purchase of a licence. Note: the Academic version is a separate product and is available to educational institutions only upon request; the academic version does not include any of the V4 updates.

WRATE uses a number of databases to support the modelling of waste management systems
and these are shown diagrammatically in the following figure.
Editable databases include energy mix (apart from the Academic version) , waste composition and foreground processes (waste management processes embedded in the model). The project database is entirely user defined and WRATE does not come with any default projects. The background inventories (the life cycle inventories for the construction materials and consumables used when developing and applying process) is based on ecoinvent data™ v 2.1. The Life Cycle Impact Assessment methodologies database is not an editable database but contains the impact assessment models available with this version. WRATE V4 comes with six impact assessment models based on global warming, acidification, aquatic ecotox, human toxicity, resource depletion and eutrophication.
