Cadaver cooling on solar energy

At a livestock farm in Flanders dead animals are picked up by Rendac, a company dedicated to the processing of animal carcasses. Logistically the collection of these carcasses is a real organisation where the residence time of these dead animals on the farms of origin needs to be kept as short as possible. However, this can in the summer, where there is also a higher risk for some species, have an unpleasant effect as regards to smell nuisance to the environment. The livestock farmer to prevent an infection and as soon as Rendac has been informed, has to keep the carcasses on a paved, covered (sheltered) pick up area away from the proper road of the facility and from the vicinity of the public road to prevent the spread of disease by this pickup transport between the various livestock farms. For some livestock farms this means that the livestock carcasses will end up laying close to neighbours as well as a reasonable distance away from the farm itself.

In order to limit this smell nuisance the last few years refrigerated carcasses boxes are available on the market. These have the advantage that they are closed, are environmentally clean and, in addition, the carcasses can be kept at a temperature < 10 °C making the decomposition and related smell nuisance a slower process. 

To activate this cooling a connection to the electricity network is often a requirement and at the location of the carcass cool box - some 100 metres of the facility - it is not easy to have such utilities and they must be fitted at the expense of the farm.

That is why the idea is to achieve the required energy through solar panels. The period when most of the cooling is required corresponds to the period of the most hours of sunshine.

When these can also be installed on top of the carcasses boxes this has the additional positive effect of shade. In addition, in The Netherlands there are also already carcasses boxes available that are built into the ground and therefore require less cooling.

Still, it remains necessary in both cases to provide a battery to cool sufficiently in periods with less sun.
