Provided herein is a dyed substrate with at least 70 wt. % of dyed PLA-fibres having a poly(lactic acid) content of at least 70 wt. %, the dyed substrate having a total poly(lactic acid) content of at least 70 wt. %. The dyed PLA-fibres are dyed with one or more disperse dyes, and the dyed substrate has the following CIELAB colour: 0≤L*≤25; −5≤a*≤5; and −5≤b*≤5. A method of preparing the dyed substrate is also provided.

Dyed substrate comprising poly(lactic acid) fibres

A dry cleaning system arranged for washing articles employing a cleaning solution. The dry cleaning system includes a wash tank () for washing an article to be washed with a cleaning solution. The wash tank () is arranged for washing the article at an increased pressure compared to atmospheric pressure. The dry cleaning system includes a fluid displacement device (), such as a pump, connected to the wash tank () and is arranged for transferring the cleaning solution through the dry cleaning system in a first operational mode. The fluid displacement device is arranged to reduce the pressure in the wash tank towards atmospheric pressure in a second operational mode.

System and method for washing articles employing a densified cleaning solution, and use of a fluid displacement device therein

The invention provides a photo bioreactor () comprising a vessel () containing an aqueous liquid comprising a photosynthetic culture and a light distributor (). The light distributor has a surface () arranged to receive light () and a tapered surface () arranged to emit at least part of the received light. At least part of the tapered surface. () is submerged in the aqueous liquid comprising the photosynthetic culture. Light may be distributed efficiently in the aqueous liquid comprising the photosynthetic culture by relatively simple and cheap means. The reactor allows a high illuminated volume fraction.

Photo bioreactor with light distributor and method for the production of a photosynthetic culture

The invention provides a photo bioreactor comprising an aqueous liquid comprising a photosynthetic culture and a light distributor (). Each light distributor has a surface arranged to receive light and a surface arranged to emit at least part of the received light. At least part of the surface is submerged in the aqueous liquid comprising the photosynthetic culture. The walls of the light distributors define a fluid filled cavity.
