Ok, Assuming that your city has plenty of educated Sims generating recyclable waste, and that your Recycling Center has proper road access and power and water, then you need a couple more things. First of all, you need trucks to pick up the bins that your Sims are leaving out for you--add garages for them if your existing recycling trucks are unable to make the rounds and collect from everywhere before the day ends. You will also need enough delivery trucks at the Recycling Center to carry away the recovered Metal, Alloy, and Plastic and take it either to your factories (Processor or Electronics plant) or to export at a trade depot/port. Finally, you will need enough processing modules at the Recycling Center to handle the waste stream--each one will consume X tons of waste and output Y tons of recovered material (you can choose between Metal, Alloy, or Plastic recovery modules). This last bit is important, because if your Recycling Center's waste storage is full, it will stop accepting further waste until it has digested what it has, and if its storage area for the recovered metal/alloy/plastic is full, then it will stop processing until a truck can empty that as well. In sum, a Recycling Center works just like any of the City Specialization factories, only its input is the collected waste and its output is the recovered material.

Regular police can only arrest criminals once they have committed a crime. However, once there is a University with a School of Law in your region, you can build the Detective's Office module at a Precinct. A Detective can go into criminals' hideouts and arrest them pre-emptively.

AFAIK, trucks that are entering/leaving the city (i.e. importing/exporting) will not use service roads, but trucks that are running entirely within your city (e.g. coal mine delivering to power plant) can use the service roads.

The game allows you to place signs for a lot of city service buildings. Do these signs actually do anything besides cost money, take up space, and look nice? If so, then what do they do?

In short, you do not have to have the entire stock of resources on hand all at once--you will be able to send it off one truck load at a time as it becomes available.

Ok, first of all, your Grade School is redundant with your High School. This version of Simcity does not track the individual ages of Sim kids, so you are better off just bulldozing the Grade School(s) and expanding the High School to accomodate all of the kids (High School is more effective and cheaper on a per-student basis than Grade School). The same goes for the Community College vs. the University. You can just add dormitories to your University in order to expand its capacity, and then bulldoze the Community College. In fact, you should also do this because the University allows you to upgrade it with additional schools (Law, Engineering, Science, etc.) based on how many students attend it, so it is in your interest to move all of those Community College students over to the University.

What exactly does the School of Business that you can add to the University do? The in-game description is unclear, and there appears to be no building/module that requires it as a prerequisite.

You can, but be aware that deliveries from the trade port to destinations within your city will be via truck, which means that you should add extra truck garages (up to the maximum) at the port. Also, you must have storage lots at the port for the coal/ore that you wish to import, and then select "import" from the trade port's control panel for each commodity.

A lof of the time, when I place a building, the computer wants to orient the building so that the snap-points (where expansion modules would go) are against the road (where there is no room to build the extra modules) instead of sitting in the empty space where they would be if the building faced the other way. Is there a way to manually control which way a building will face when I place it, short of moving the roads?

Most likely your trucks are stuck in traffic. You will have to either extensively restructure your city to reduce overall traffic, or else wait for the pathfinding patch (hopefully within the next week or two).

You get one truck when you place the depot, but you can place up to three more, for a total of four trucks. If stuff is not moving in and out of your trade depots fast enough (i.e. it is stuck at full capacity), then you need to add more truck garages.

There are two reasons that this can happen. First of all, your refineries and oil power plants (or other consumers of oil) may be using it up faster than it can be replenished. Check to see that the delivery trucks are not stuck in traffic too much--if they are, then a refinery may use up its stock while waiting for more. Also, if oil is building up at the oil wells (i.e. their local storage gets full even part of the time), then add delivery truck garages to the oil wells up to the limit allowed. Second, the oil may not be getting routed to the oil consumers in the first place. Make sure that all oil consumers are set to "accept local deliveries". Also, if their oil stocks are low, then go to your trade depots/ports and tell their oil storage lots to use the oil locally instead of exporting it--this will redirect deliveries to your local consumers.

Yes.. that will be really nice, destroying garbage permanently without causing air or ground pollution. No, I didn't mean burn it with zero pollution--I meant that it might produce maybe only half as much pollution as the regular incinerators, sort of like how the "clean coal" power generator produces only half as much pollution as the regular coal power generator.

It would be nice if they had an "advanced" incinerator that burned more garbage while producing less pollution per ton of garbage burned, but would have to be unlocked by a University research project, just like the "clean coal/oil" and other advanced power station generators.

Another thing that you can do is to build the Trade Port as soon as it becomes available and connect it to your rail line (if one runs through your city map) or the waterfront (if you have that). Rail/water transport will let you ship cargo in and out while bypassing road congestion entirely.
