One is crushed the concrete at a recycling plant facility and the other one is with a mobile plant. Each method uses basically the same procedures.

Concrete Production an overview ScienceDirect Topics

Jorge de Brito, José D. Silvestre, in New Trends in Eco-efficient and Recycled Concrete, 2019 11.3.1 Recycled aggregates. As concrete production keeps on increasing worldwide, so does the use and consumption of abiotic resources, such as aggregates. To corroborate this statement, the worldwide aggregates demand will raise from 45.9 to 66.3 Gt in a time span of 10 years (e.g., 2012–22
