Promising results after first trials

During the month of June, the teams from AITIIP, PCTAD and CSIC-EEAD carried out the preparations of the land for the first trials with tomatos, cucumbers and peppers on the demonstration sites. Since these were the first tests, the monitoring and evaluation tasks were very detailed. During the following months and until each harvest, the project's technicians visited the fields to study the functionality of the different biodegradable batches and compare them with the controls. Meanwhile, PCTAD and ARCHA have conducted their own laboratory studies, comparing fruit and vegetables post-harvest, and heavy metal/biodegrability studies of the plastics, respectively. 

Photos of the tecnhical monitoring visits can be found below. The results and preliminary conclusions obtained so far are:

  • Among the three types of biofilms, only one has acheived an acceptable biodegradability rate. In the other two cases, biodegradation has begun too quickly.
  • There has been more difficulty in removing the biobags for fruit protection compared to the conventional ones. Although this has been compensated by no waste management afterwards.
  • The sensorial and olfatometric analyses for the fruit and vegetables harvested have given very po​sitive results.
  • The biomulching with the best degradation rate has also demonstrated a higher resistance to weeds.
  • In general, the plastics with less exposure to light and water have worked better.
