My PhD in the microwave

Figure 2: Glassy bottom ash produced by microwave thermal treatment.

One of the main features of the current consumer society, is materials production for mass consumption. This results in the generation of huge amounts of (municipal solid) waste (MSW). The social, environmental and health risks linked to the disposal of waste in landfills has stimulated the European Commission to implement solid waste management policies. The main practices in waste management ...

Coping with negative feedback

Screenshot from

“You said you worked hard? Well, maybe you need to work a little harder. Is that really the limit of your strength? Could the you of tomorrow beat you today? Instead of giving in, move forward.” After many months of article reading, experiments and data analysis, I came out with my first scientific article. Despite reading literature and scientific documents ...

Upcycling of residues from the plasma gasification of waste

Europe contains between 150,000 to 500,000 landfill sites, from which 90% could be “non-sanitary”. Remediation actions will soon need to take place in order to prevent any environmental and health problem that these non-sanitary landfills could cause. Enhanced landfill mining (ELFM) could be a solution to manage these landfills and also to reclaim land for society benefits. In ex-situ ELFM, ...

NEW-MINE successful Midterm Review & 4th Network-Wide Event in Leuven (Belgium, September 2018)

a happy newmine consortium

The first day, on Wednesday 5/09, the materials flow of the project was discussed in a workshop managed by the ESRs of work package 4. The general approach of the assessment of Enhanced Landfill Mining (ELFM) by WP4 and the data input required by ESRs were presented. Subsequently, performance parameters of the different processes were discussed in working groups. The ...

All roads lead to… a landfill

Image from Hindustantimes

At present, almost all that we consume goes in a direct or indirect way to a landfill, and from there, our waste starts to degrade itself producing greenhouse gasses and leaching a lot of toxic compounds which could contaminate our aquifers, our most pure source of water. The organic material starts degrading immediately, but the other fractions need up to hundreds ...

One Cappuccino please! NEW-MINE present at Researchers’ Night (University of Padova)

Acacio and Patricia experimenting b

NEW-MINE contributed to the Researchers’ Night in Padova, held on September 28th. Prof. Enrico Bernardo, with the help of ESR Patricia Rabelo Monich, showed the activities concerning the upcycling of industrial waste (comprising waste glass) in the manufacturing of glass-ceramic foams. They demonstrated the obtainment of glass foams by alkali activation of suspensions of glass powders, followed by intensive mechanical stirring. ...

Have you ever thought about composting at home?

Figure 1: Making-Compost. (Source:

Since long time ago human kind has practiced composting as a common activity and, therefore, nowadays there are many different techniques available for processing our organic waste and turn it into a natural soil conditioner or fertilizer at home. Such practice contributes to close the natural cycles of carbon, nitrogen and phosphorous and avoids the need of the application of ...

Most probably interesting – Bayesians vs. Frequentists

Figure 1: No one actually knows what Thomas Bayes looked like, but this is the picture that everyone uses; next to him you see his famous theorem.

Today, I want to tell you something about probability. Most people who hear this term intuitively understand what it means. If someone tells them there is a 90% chance for rain they know: better pack an umbrella today. Looking more closely, there are different definitions for probability in science and philosophy. In this blog post, I want to briefly introduce ...
