The Home Composting (online) course offered through Curitiba City Hall's Aprendere Portal is accepting registrations until November 15, 2026. The course is online, has a 4-hour workload and originally offered 400 places. The published target audience is “PMC employees and the community,” so participation is not restricted to municipal employees.
During the editorial check on September 15, 2026, class 74954 showed 118 places available. That counter is dynamic and may change as people register, so anyone interested should check availability directly on the official course page.
Who can take the home composting course
The official listing defines the audience as Curitiba City Hall (PMC) employees and the community. For people who are not municipal employees, the Aprendere Portal itself offers a “Community” access option linked to a CPF number. The course page does not list an academic prerequisite, minimum age or a requirement to already participate in the municipal composting program.
This means the course should not be described as training exclusively for public employees. At the same time, the public listing does not state a specific residency rule beyond the broad “community” category. Anyone with a particular registration question should use Aprendere's own channels rather than assume a requirement that is not stated in the official offer.
Registration checklist before November 15
| Step | What to do | What to check |
|---|---|---|
| 1. Open the listing | Go to the “Home Composting (online)” page on the Aprendere Portal. | Whether the status is still “Registration Open” and whether places remain. |
| 2. Sign in | Municipal employees use the credentials indicated by the system; community participants choose the “Community” option. | On a community user's first access, enter the CPF and follow the portal's instructions for registration or password setup. |
| 3. Confirm registration | On the course page, select the registration button and complete the information requested by the system. | Registration details and email address, because course access information is sent by email. |
| 4. Watch your email | After registering, wait for the instructions to access the course. | Inbox and, if necessary, spam or junk folders. |
| 5. Do not wait until the deadline | Register before November 15, 2026. | The published deadline does not guarantee a place if the class reaches capacity earlier. |
The Aprendere login page says that “Community” users should continue, enter their CPF and registered password. On first access, the system provides the next instructions. The course listing also states that, after registration, access information will be sent to the email provided.
What the 4-hour course covers
The syllabus is divided into three modules. The first explains why to compost, what composting is and its benefits. The second focuses on practical aspects: what a composter is, construction, digestion and collection boxes, worm composting, what can and cannot go into the system, raw materials and aeration. The third covers where and how to use compost and presents different composting methods.
The official objective is to present composting as part of the food cycle and highlight benefits such as reducing the amount of household organic waste sent to landfills, producing compost for garden beds and pots, and using the liquid generated in the process as a natural fertilizer, as described in the course.
The online course is not the same as applying to receive a composter
This distinction helps prevent a common misunderstanding. Curitiba City Hall also runs the COM-POS-TE Curitiba Municipal Composting Program, which has distributed home composting kits and monitored participants in specific initiatives. The program page links to the online course as guidance material, but treats program participation and composter distribution as a separate process.
On the institutional page checked for this article, the COM-POS-TE participation section says “New registrations coming soon”. Therefore, signing up for the 4-hour course should not be interpreted as a guarantee of receiving a composter. When the city opens a selection or distribution round, it publishes its own rules and steps.
What participants are expected to do: the course and the program have different requirements
For the online course, the public listing describes registration, remote access and the syllabus. The class listing does not require participants to weigh waste, answer monthly questionnaires or maintain a composter supplied by the city.
Those responsibilities appear on the COM-POS-TE Curitiba page for participants who receive and use a program composter: they must care for the equipment, record how much waste is added, answer monthly questionnaires and notify the city if they withdraw. Applying those rules to the course itself would create requirements that are not stated on the training page.
What if you already took the course in a previous year?
The 2026 listing includes a specific notice: anyone who completed the course in previous years may take it again, but will not receive a new certificate. This matters for people who want to repeat the material simply as a refresher.
