ESF biofiller

from general waste

The ESF biofiller are our technological biofillers obtained from pre-consumer food wastes. These residues are supplied by different local food companies. The ESF biofiller can be supplied in different grades:

ESF B grades
ESF Advanced grades
ESF Master grades

ESF B grades

The ESF B grades are our most versatile grades which can be successfully used in many applications thank to their low and controlled particle size distribution and to their controlled moisture values

ESF Advantaged grades

The ESF advanced grades are our customized biofillers optimized for specific applications. We can improve the hydrophobicity, the dosability and flowability, the colour and the mechanical response of the biofillers.

ESF Master grades

ESF biofillers can be concentrated (up to 50-60%) into masterbatches using polyolefinic or biodegradable resins as carriers to facilitate their use for plastic applications
