Other than these, there were also some more essential processes like the Oil pressing facilities. These would be needed for cooking, lighting, soapmaking, and preservation.
Some sections could also have a dedicated use in war. Rather, this one was easy to convert to "war mode", and would churn out the oil needed for their wars at the clap of the hands.
There would also be a plastic factory.
However, rather than just the petrol from Dune Town (which was mostly used for bitumen roads and fuel oils for some machines being developed), they were also using corn starch, sugarcane, and plant oils for the biodegradable variety.
This was not to say they were completely doing away with petrol-based plastics just because they cared about sustainability. They were still using them, though in select applications, and definitely not as a consumable item.
The plastic products using petrol would be those with very sensitive applications and areas where they could not be melted. For example, the ones used in machinery components and medicinal tools, where higher durability and precision were required.
They didn’t want machines breaking, or even exploding, because of a random and avoidable leak, right?
They didn’t want medical tubing to burst when used near a fire user, either.
That said, Petrol-based plastics could actually be made biodegradable, as it had been done in Terran before. It was just that the process was a bit more cumbersome and resource-intensive, and therefore not practical for them to explore just yet. For now, the balance between the two kinds was what they’d pursue.
And then (although there were also others), there was the Paper mill and Print shop.
The Alterra bookstore was intensely popular, especially for the literati. The consolidation of the terran region alone meant a huge guaranteed market of literates, book readers, writers, and so on.
According to the recent news, there was a large buy-off of Otto fanfiction in a few allied territories.
It seemed like the people Otto rescued fantasized about him a lot.
Alterran Paper and Stationery was also gaining popularity outside of the region, too. According to Bart, the rims and rims of paper they bought would always be purchased by nobles within the first few minutes they would come out.
These factories were just the ones assigned to Amber’s team. Boss Briana was training another team lead, and he’d be handling another batch and another set of factories. It was all very exciting.
There was also a small railway system that would run in this area. Each lot in the industrial area was much larger than the ones inside, so traveling from a factory all the way to the end, where the depots would be, could get quite cumbersome.
Some items were also quite sensitive to transport. For example, they had used the broat carts for glass before, and they had a few wastages.
The crops that would be given priority were determined by Gru’s agricultural department and underwent rigorous market studies, as well as the needs (current and future) of the territory itself.
They had all given honesty oaths, so Althea didn’t have to worry about anyone being bribed or lobbied to push for specific props.
After all, the abundance of certain crops meant cheaper production costs for the specific industries that used them! Alterra was growing big, and it wouldn’t be a surprise that under-the-table discussions would take hold, and in that case, they could only be thankful for the Oaths!
The underground farms were also not left behind. People liked their mushrooms, and there were already plenty of mushroom-derived products circulating in the market.
Not to mention, certain leafy greens also prefer underground planting, like lettuce, spinach, arugula, and so on. Of course, some root crops were as well, and there were also plenty of herbs that would take advantage of this. These were built under the system farms, so they also gained benefits from there.
No matter the disaster, and even if the rest of the world went hungry, Alterra was definitely not going to suffer with them.
After these zones were done in approximately one month, the rest of the territory would be developed step by step, and some items were already assigned to another Phase, though that would be for much later.
Anyway, people were already excited about what the new territory would look like!
