The BSX-ASL hybrid photobioreactor exploits sunlight and artificial light generated by a high-efficiency LED cover. The base unit is composed of a modular process skid featuring 32 photobioreactors (28,000 l; footprint <200 m²)



The BSX-SLP solar concentrator photobioreactor takes solar radiation and directs it into the photobioreactors via optical fibers and diffuser tubes. This system allows natural radiation to be used through a “light dilution” mechanism. The BSX-SLP reactor is ideal for cultivation in sites with high levels of direct normal irradiation (DNI).

  • Scalable and modular
  • Work in synergy with existing plants
  • Make use of industrial by-products

  • Offer a high level of automation
  • Manage the light intensity and spectra
  • 24/7 production


The integrated ASL system allows cultivation in climate zones which would otherwise not be favorable.

The presence of an integrated LED cover on the top portion of the bioreactor makes this system suitable both for outdoor and indoor installations.

In order to guarantee even light distribution, we have patented a light tube system which allows gradients of luminous intensity to be avoided along the profile of the bioreactor.

On the basis of the cultivation specifications, we design modules which can be customized to the customer’s requirements, both as regards the volume and dimensions of the photobioreactors and the light spectra.


The BSX-SLP solar concentrator photobioreactor offers the feature of transferring the solar radiation, concentrated by solar tracker panels, to provide direct normal irradiation (DNI) to microalgal cultures as well as plants grown in the vertical farming sector.

The concentration of the direct solar radiation is performed by an optical focusing system (“parquet” of Fresnel lenses) and a dual-axis solar tracker coupled to the optical fibers.

Based on photosynthetic properties of microalgae, the experimental application intends to provide an antidote to global warming for those urban areas where the combination of new green infrastructures is limited – due to lack of space – by the existing roads, sidewalks and services.

The BIOBOSCO Urbano® with its 10 m2 of footprint absorbs CO2 from the atmosphere and releases O2 into the environment in a quantity comparable to a grove of approx. 25-30 trees. The architectural design can be customized to fit to different urban contexts.

CEO Dr. Giovanni Gnudi reports:
“This is an experimental application that intends to provide an antidote to global warming for those urban areas where it is not possible, due to lack of space, to combine the coexistence of public green, roads, sidewalks, and underground utilities.
BIOBOSCO® urbano is a technology designed to be complementary and supportive to the implementation of public green in those contexts where urban infrastructure has a high land consumption.
In just 10 m2 of occupied land, in fact, BBU® absorbs CO2 from the atmosphere, releasing oxygen into the environment, in an amount comparable to a grove of 25-30 trees in about 500 m2 of land.
We are aware that this is a small contribution to the environment, but with its small size and customizable architectural structure, we are able to adapt it to various urban settings.
The company is currently working to bring new installations, in addition to the one already done for Eni at the former Gazometer in Rome (featured in the photos), along stretches of highways, railway stations, subways, ports and airports in Italy and abroad”.

The biomass produced inside Eni’s site (ex-Gazometro Ostiense) is delivered to a facility of Self Garden Srl that produces compost for horticultural applications.

Main collaborations: Self Garden Srl (compost), Consorzio Italiano Compostatori (CIC), Arch. Cesare Griffa (designer); C-LED Srl (lighting), Scubla Srl (plant builder), CodeBaker Srl (hardware-software interface); Eridani3 (architectural builder), Aksolar Srl (photovoltaic panels).
