Waste classification issue

There appears to be a classification issue here. Waste in this dump is classified as hazardous. However when i sent a truck to collect and move it with no specific orders, it collected and moved just a tiny amount of mixed waste. So, i switch it to pick up hazardous, and it picks up, except it is classified as mixed waste in the truck and even has an export value (i suppose it is because of the waste construction material). I should add that i was a bit puzzled it was classified as hazmat anyway, because the truck that moved waste there was supposed to pick up ash from the incinerator exit dump. Unloading that to the separator imput dump gives no more trouble, it stays as mixed way.

I guess the truck has the mixed waste from another trip. Hasmat is nothing else than mixed waste which is contaminated.
Once it gets processed it will turn into mixed waste.

You can send the truck straight to the customs to get rid of his current cargo. After that he will pick up hazmats.

You can apparently have more than one type of waste in a single dump. If you dump hazardous waste in a dump with mixed waste, all of it becomes "hazardous waste". However, if you then remove hazardous waste from that dump, the remaining waste may become mixed waste again.

Your screenshot shows "hazardous waste" which is actually over 50% construction waste, so I am guessing you have been dumping construction waste in there along with the hazardous waste. Your garbage truck has a chance of picking up some of the non-hazardous waste, after which it will not load any hazardous waste, if it had orders to load only hazardous waste.

The short term solution is to order your truck to load any waste without specifying the type. Though eventually, you will want to bring it straight to the processing plant/border post without using any intermediate dump sites, especially sites that hold non-hazardous waste, since hazardous waste is the most expensive type to get rid of. You'll want to avoid contaminating any other waste with it, since that leads to higher processing/export costs.

not the truck was empty..it was just weird how it kept changing that is all, as for the constuctrion waste, i think it just flies through the incinerator, right?

Hazardous waste sometimes is mixed with mixed waste. Some players even mix it intentionally to make mixed waste to be unloaded border faster. Waste is still half baked and needs more work on it.
