Early Anaerobic Digestion(AD) of Municipal Solid Waste experiences, presentation of the experience in spain of the building and operation of 42 MSW AD plants.
Operation biggest problems associated with the design, process and operation of anaerobic digestion and some of the main improvements over the period that helped this first designs.
Early AD experiences in MSW in sapin was a transliteration from german facilities on a time where AD was thougth to be almost magical conversion of waste to energy. So preparations where made to take untreated and unsorted wastes to be converted to energy on technology relying a much more evolved society.
Also in Spain, the technology was sold to add value to the refusal waste where the organic fraction was supposed to be absent. This lead to some of the biggest issues related to the technology and how mechanical pretreatment of the waste had to be dramatically improved in very short notice.

21. A new “vision” was needed
“Bring me a bottle of wine, so that I may wet my mind and say something clever” Aristophanes
La Rioja experience: X‐Ray vision, the superpower we needed
23. * The materials (1) are uniformly distributed on the belt. * A power X‐ray source (3) produces an X‐ray radiation that penetrates the material. This radiation is absorbed in varying degrees depending on the atomic density. *The remaining radiation is detected by X‐ray camera (2) equipped with sensor DUOLINE®.

24. Key Takeaways
KEY TAKEAWAYS
1.
To learn you need to make mistakes and experience is no other thing than overcoming those mistakes successfully.
2.
As a result of this learning process, we are now able to build AD plants, capable of treating Mixed MSW that, ultimately, produce biogas that can be used as a source of both, energy and heat.
3.
Our company can draw on its deep expertise to translate should‐be designs into reality.
