Emissions reduction

Cover Ball offers a simple and quick solution to the problem of odors and harmful gas fumes deriving from zootechnical/industrial waste collection basins. Once placed inside the storage tank, the spheres arrange themselves on the entire surface, covering up to 91% of the entire area and reducing evaporation by up to 90%.

Subject to the best available techniques described in the European BAT, it is a floating roofing system suitable for all surfaces, but even more so, for all those zootechnical and industrial wastewater collection basins which, for reasons of size, cannot use other roofing systems for the reduction of emissions into the atmosphere.

Odor is a sensation resulting from the interaction of volatile chemical species inhaled through the nose, including sulfur compounds (sulphides, mercaptans), nitrogen compounds (NH 3, amines) and other volatile organic compounds (esters, acids, aldehydes, ketones, alcohols).

Cover Ball offers a quick solution, free of maintenance and any replenishment, for the reduction of odors deriving from storage of processing water of any kind:

Animal waste processing industry;
Landfills; Livestock;
Animal slaughter plants;
Oil industry (storage park);
Paper industry;
Composting activities;
Liquid waste purification systems

Technical Features

  • Easy installation. The spheres, once introduced into the tank, naturally assume an equal distribution over the area
  • Rain water. Unlike fixed roofs, the spheres allow rainwater to pass through. This allows you not to have any type of stagnation
  • No Maintenance. No type of maintenance or reintegration over time
  • The spheres follow the level of the liquid and allow any type of work inside the tank
  • The material with which they are built (HDPE – high density polyethylene) guarantees a long life to the cover
  • Virgin HDPE, therefore totally recyclable at the end of its life


  • Quick and easy installation
  • Each sphere is built to live a long time and free from "Biosphenol-A"
  • No type of maintenance
  • It allows any type of operation through the liquid
  • Fast and concrete solution against odor problems
  • Significant reduction of polluting gases
  • Reduction of UV exposure
  • Excellent deterrent against birds
  • Algae reduction
  • Wind resistant
  • Excellent behavior with frost, snow and rain water
  • Continuous coverage 365 days a year
