The impact of the format.
What changes when a rapid test is made on a continuous roll instead of one molded cassette at a time.
A design target of 92 percent less material per test.
One housing holds 100 tests instead of one, so the plastic that is not part of the test itself is shared across all 100.
−92%
Material per test
32.2g cassette kit → under 3g per test
−86%
Plastic per test
about 11.6g of plastic → about 1.6g per test
−94%
Transport volume
80m³ → 5m³ per million tests, counting each product's own packaging
Weight that does nothing
A conventional kit averages 32.2g of materials per test, most of it packaging rather than the test itself. The roll format removes the cassette and most of the packaging around it. Freight and waste disposal are charged by weight and volume, so a lighter test costs less to ship and less to throw away.
Cleaner disposal
The materials are chosen to burn cleaner than a cassette kit, with none of the plastics that give off toxic dioxins when medical waste is burned. The test is designed to go through regulated medical waste handling.
Where these numbers come from: baselines of 32.2g and 36 percent plastic per test from Wöhrle et al. 2025, Bulletin of the World Health Organization. The CENTiV figures are design targets.
Across 21 commercial kits, a conventional test kit averages 32.2g of material per test, and plastic makes up 36 percent of a standard cassette kit. Both figures are from Wöhrle et al. 2025, Bulletin of the World Health Organization. The plastic per test is our calculation from those two figures; the study does not report it directly.
For CENTiV we count the whole 100-test roll, including the housing, the buffer, and the packaging, divided across its 100 tests. The 80m³ shipping volume for conventional kits is our own calculation, counting each kit's own packaging.
The CENTiV figures are design targets and our own estimates.

Less material, less plastic, less freight
CENTiV™ is designed to cut the material, plastic, and transport volume of each test, in line with three of the United Nations Sustainable Development Goals.

SDG 3 - Good Health and Well-Being
The first panel is for antenatal care, where three infections that pass from mother to child can be caught at one visit. The KiOSK serves a different need: no one else has to be there, which matters most for HIV and sexually transmitted infections, where stigma keeps many people from testing.

SDG 9 - Industry, Innovation and Infrastructure
Roll-to-roll production uses an established industrial process instead of molding a part for every test.

SDG 12 - Responsible Consumption and Production
Wherever testing runs at volume, the roll cuts single-use plastic and the material that travels with it.
