TAPVEI® is the world’s leading producer of aspen products for animal welfare.
Since 1982, TAPVEI® has been producing the highest quality bedding, nesting material and environmental
enrichments for laboratory animals. TAPVEI® is a quality- driven company, providing
controlled laboratory environments for your animal research. In our production process we use
naturally grown Nordic aspen (Populus tremula) and renewable energy.
There are various reasons why the highest quality laboratories prefer aspen products to other raw materials (softwood, corncob, cellulose).
Most specifically, the discoveries of softwood bedding cytotoxicity and its effects on the metabolism of pharmacological agents under research have prompted research labs to switch to aspen bedding.
Additionally, mice and rats alike generally prefer aspen chips over softwood sawdust and corncob bedding. From amongst various types of hardwood, aspen is preferred due to its lower dust count. Aspen bedding shows high absorptive properties, and hardwood in general guarantees the lowest ammonia concentrations in rodent cages. Even when purposely contaminated with fungi, aspen chip bedding does not encourage the growth of fungi in the rodent cage environment (see Additional reading sections for references).
All TAPVEI® products are made from aspen (Populus tremula) – a natural hardwood from the pristine Nordic environment. Out of the multitude of studies carried out with various species and animal breeds, hardwood materials are typically found to produce the least undesirable side effects on experimental results.
The whole production process of TAPVEI® products follows high ecological standards. It starts with using untreated raw material from the intact Nordic wilderness under a Forest Stewardship Council® certified (FSC®) chain of custody and is followed by use of bioenergy for heating the production plant. Our products are biodegradable. Quality is ensured by applying the ISO 9001:2008 and ISO 14001:2004 standards.
Finished products are regularly tested for microbiological, chemical and environmental contaminants in independent laboratories. All TAPVEI® products are compliant with GV-Solas requirements for animal feed.
With the obvious effects that TAPVEI’s production of natural bedding, nesting and enrichment products have on the environment, ecological thinking and activities are inevitable in our business. In order to minimise environmental impact, constant attention is paid to decreasing and avoiding possible ecological harm. As a part of this process, we follow the responsible forest management practises of Forest Stewardship Council® (FSC®), an international organisation that guarantees the origin of raw material. The management system of TAPVEI Estonia OÜ has been approved by ISO 9001:2008 and ISO 14001:2004 standards.
