Dr. Paulo Trazzi

Department: Chemical and Environmental Sciences
Address: University of Limerick
Qualifications: Ph.D. in Forestry Enginner
Email: paulo.andre.trazi@ul.ie
Supervisior: Witold Kwapinski

Paulo graduated as Bachelor in Forest Engineer at the Universidade Federal do Espirito Santo. He did Master in Forest Science at the same university, when he worked on utilization of residual biomass to production of forest seedlings.

Paulo completed his Ph.D. in Forestry Enginner at the Universidade Federal do Parana. He worked on the use of biochar in the seedling production and in the initial field growth of pinus tree. Part of his Ph.D. was done at University of Limerick, when he worked on P adsorption by biochars from sugarcane and miscanthus.

Current Project

"BIOCHAR FROM AGRO-WASTE FOR P AND N MANAGEMENT”

Effective management and recycling of the organic matter of animal manures contribute to soil fertilization, and reduce the requirement for the provision of mineral N, P, K and micronutrients. However, significant quantities of essential nutrient in slurry are present as organophosphates and amino acids and are therefore not available for plant uptake so end up in water courses with consequences for the environment.

The project investigates in practice a possibility to apply existing pyrolysis technology to mineralize the P and N in solid residues and create a biochar with properties that facilitate adsorption of the N and P from agri-food slurries, resulting in a form of fortified biochar with plant-friendly forms of nutrients concentrated on a media that will restrict loss to runoff or atmospheric emissions, and that can be readily managed and packaged making it valuable as a retail or wholesale soil additive.
