» Start-up of the AD experimental plant at the
Industrial Engineering School of the Extremadura University
in Badajoz: It is the beginning of an R&D&I
project for the treatment and valorization of liquid
and solid slaughterhouse waste in a full-scale plant.
The plant simulates a two-phase anaerobic digestion
reactor, taking advantage of the biogas in completely
mixed and discontinuous reactors by re-compression
of the biogas. The aim is to evaluate the treatment
efficiency of the system and to extrapolate the results
to the territory of Extremadura, accounting for the
existence of a network of slaughterhouses and meat
processing plants, and the valorization and utilization
of the subproducts from the AD process.
These are:
• biogas as an alternative energy source.
• solids for quality compost.
• liquids with different nutrient concentrations
for energy crops.

In Aragon, the first “Manure Management Centres”
have been launched. The design of three of these centres
is being finalized, one for each province (Huesca, Zaragoza
and Teruel), with the involvement of private initiative,
some ADS and livestock farmers, and the possibility
for town and city councils to participate. In the first
phase, the aim is to treat the liquid manure to the
most adequate level for each zone, in the second phase
to compost the solids, and in the third phase to achieve
anaerobic digestion and biogas utilization. The solids
will be composted together with residues from pruning
and cleaning up of lower regions. |

In Castilla-León: the livestock farm “Bascones
del Agua” near Lerma (Burgos) is being analyzed
for the design of an ambitious project that will valorize
the slurry and manure of 50.000 pig heads and 1400 milking
cows. |

In Catalonia, three plants are the initiative
of different municipalities in the regions of Osona
and El Vallés Oriental, each one with a design
that is based on local needs and accounts for all the
local manure surpluses. The projects are developed in
phases: initially they focus on the reduction of nitrogen
surpluses in vulnerable zones, and in later stage the
viability to expand the plants via aerobic digestion
with biogas utilization is considered. |

In the USA, mobile units are in the construction
phase. They are transportable on trucks or 24 Tm tractors,
and can be used for the treatment of abandoned lagoons
and for continuous treatment of small livestock farms |
