The senior technician of the Environment, Sergio Ramos, attributes the decline in previous years to fewer investments and projects, why they used less reactive. However, it is noteworthy that the highest peak the last fifteen years was registered in 2010, during the crisis, with 21,384 kilos, followed by 2009 with 21,106, while the 2014 is third. The Department of Environment warrants for the support of the University in the early years of the crisis, until the cuts took their toll on the institution to become more evident.

The powers of Chemical Sciences and palm as regards the generation of such waste due to the amount of handling takes solvents, although in some cases, if they are homogeneous, can be regenerated. Just between the two centers account for more than half of the total hazardous waste, namely 11,141 kilos. Science Gesuga company takes over the products of animal origin, called SANDACH. It is mice and fish unfit for human consumption and used in research. At the moment the amount is testimonial, about 80 kilos a year.

Eight out of ten kilos of waste coming from the Vigo University campus, while Pontevedra and Ourense are minimal and come mainly Fine Arts, Forestry and photo labs.

Other facilities that produce hazardous residues are the Support Center for Scientific and Technological Research (Cacti), which is included CITEXVI, Marine Science Station of Toralla (ECIMAT), the Newton building and the School of Industrial Engineering, both at the headquarters campus as Torrecedeira. Vigo production is similar to that of other universities like Santiago.

Despite the increase in hazardous waste Vigo institution conducts research and projects aimed at reducing the material. Among the latter is the group that develops the recycling Gruvi under the supervision of the office environment.

The discarded computer equipment is repaired and after installing free software to the computers are shared between non-profit organizations through a public call annually. In the last call they will be able to recover nearly four teams, divided between thirty associations.

Sometimes researchers can convert waste as does the researcher Xanel Neighbor, Department of Chemical Engineering. In his doctoral thesis he opted for the use and appreciation of remains of the wine industry and processing of corn to obtain products of industrial interest as biosurfactants. These are natural detergents capable of being applied in pharmaceuticals and cosmetics, as well as bioabsorbentes, high utility in treating wastewater.

Although in most cases the university has to pay a fee for the management of certain waste, in others, such as batteries, they collect them free. "We remove them from the hands because they take everything. I think to pay, "says Sergio Ramos. Explain that sometimes the remains borne by the producers as with campus cafeterias where managers are responsible for the oils.
