we don't want to mention the actor,
we are more interested in the process/action,
what is happening is more important than who is doing it.

The stages to produce Biodiesel

The stages to produce Biodiesel
In the beginning of the process, photosynthesis is created as oil crops harness light from the sun. In the second stage, seeds are harvested from these plants. After this, crude vegetable oil is extracted from the seeds. Following this step, this liquid is purified and becomes refined vegetable oil. Alcohol is then added during the process of transesterification. This creates biodiesel as well as a separate product called glycerol, which is used for the food and cosmetic industries. Next, the biodiesel is used to power vehicles. Finally, the use of these machines creates energy as well as releasing CO2 into the atmosphere.
Slide 7 - Diapositive
To describe a process we use the passive voice & sequencing words.

How bricks are made for the building industry.
Overall, there are seven stages in the process, beginning with the digging up of clay and culminating in delivery.
To begin, the clay used to make the bricks is dug up from the ground by a large digger. This clay is then placed onto a metal grid, which is used to break up the clay into smaller pieces. A roller assists in this process.
Following this, sand and water are added to the clay, and this mixture is turned into bricks by either placing it into a mould or using a wire cutter. Next, these bricks are placed in an oven to dry for 24 – 48 hours.
In the subsequent stage, the bricks go through a heating and cooling process. They are heated in a kiln at a moderate and then a high temperature (ranging from 200c to 1300c), followed by a cooling process in a chamber for 2 – 3 days. Finally, the bricks are packed and delivered to their destinations.
