Abstract: This invention relates to a kit to enable the bio-degradability of a material to be observed. The kit includes: at least one environmental vessel formed from a non bio-degradable material having an opening that can be covered with a scalable lid for loading of the vessel, which vessel includes means so that the vessel can be sealed or ventilated if desired; at least one sample of a material to be tested. The sample to be tested can be located in the vessel and tested under the influence of a particular environment, which environment may be ventilated if desired.
