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.

Experimental application, it 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 areas, roads, sidewalks and subservices.

The BIOBOSCO Urbano TM, with its 10 m2 of land occupation, absorbs CO2 from the atmosphere – releasing oxygen into the environment – in a quantity comparable to a grove of approx. 50 trees. The dimensions and structure can be customized to adapt to different urban contexts.

The biomass produced inside Eni’s ex-Gazometro Ostiense is destined for a company that produces fertilizing soils in the horticultural field, Self Garden S.r.l. .

Main collaborations: Self Garden S.r.l. (quality compost), Consorzio Italiano Compostatori, Arch. Cesare Griffa (designer); C-LED S.r.l. (lighting), Scubla S.r.l. (skid builder), Netwark S.r.l. (hardware-software interface); Eridani3 (architectural structure builder), Aksolar S.r.l. (photovoltaic panels).
