At Zero Waste Solutions we design engineering solutions for non-standard waste that requires specific treatment before it can be converted into a usable feedstock.

Eggshell micronization: a tailor-made project
What this project solves
This development is designed for companies that generate or manage waste from the food industry and are looking for a technical outlet for materials that do not fit into conventional recycling lines.
The process can help to:
- Reduce the volume of waste.
- Transform the peel into a fine powder.
- Improve material homogeneity.
- Facilitate its use in industrial formulations.
- To open new avenues of valorization.
- Reduce the amount of waste sent to landfill or external management.
How the technical solution is proposed
Each project must be adjusted to the input material, humidity, impurity level, desired particle size and end application.
The line may include:
- Reception and preparation of the material.
- Power systems.
- Specialized grinding or crushing.
- Classification by particle size.
- Separation of invalid fractions.
- Internal transport of the material.
- Bagging, storage or preparation for later use.
- Quality control of the final product.
Possible applications:
The powder obtained from micronized eggshells can be of interest in different industrial applications, always depending on the degree of cleanliness, granulometry and technical requirements of the customer.
Some possible applications are:
- Composite materials.
- Fertilizers.
- Food supplements or applications, if the process and applicable regulations allow it.
- Mineral loads.
- Industrial formulations.
- R+D and circular economy projects.
Who is this solution designed for?
Different sectors:
- Companies in the food industry.
- Producers with a high volume of egg waste.
- Organic waste managers.
- Companies that seek to value by-products.
- Composite manufacturers.
- Industrial R+D centres.
- Companies that need a turnkey solution for a specific waste.
