Small greenhouses, maximum yield

According to UN estimates, the world’s population will have passed 9 billion by 2050.
However, the amount of arable land available is not increasing.

Cheap greenhouses made of structures covered with plastic film could offer a solution to this problem as they allow the yield per hectare to be considerably increased. Following six years’ research, BASF is launching the Tinuvin® XT 200, a light stabiliser which helps improve the yield in greenhouses by protecting the thermoplastic films from ultraviolet rays and preventing them from disintegrating quickly.

Tinuvin XT 200 allows the economical production of low-density polyethylene (LDPE) films, designed to resist high concentrations of plant-protection products. Their lifespan is a minimum of two years, even if they are intensely exposed to the sun.  In contact with the wooden or metal parts of the greenhouses, the films stabilised in this way retain excellent quality. Without the addition of light stabilisers, agricultural films would not even last the length of a harvest.
