How to Use REGAIA

Classify any waste item in seconds — upload a photo and let the AI do the rest. Follow the five steps below to get started.

Five Steps to Classification

1
Step One

Open the Homepage

Navigate to the REGAIA homepage. You'll be greeted by the main upload interface — a clean, centred panel where you can drag and drop a waste image or browse your device for a file.

Make sure you have a clear, well-lit photo of the waste item ready before you begin.

Step Two

Upload Your Waste Image

Drag and drop your image directly into the upload area, or click the browse button to select a file from your device. The system accepts common image formats and supports files up to 10 MB.

Use JPG, PNG, or WEBP formats for best results. Keep the waste item centred in the frame.

Step Three

Preview the Image

Once selected, a preview of your uploaded image will appear on screen. Take a moment to confirm the image is clear, correctly framed, and shows the waste item you intend to classify before moving on.

If the image looks blurry or cropped incorrectly, click the upload area again to choose a different file.

Step Four

Click Predict

Press the Predict button to submit the image to the AI model. A scanning animation and loading indicator will appear while the system analyses the visual features of your image against its trained categories.

Processing typically completes in just a few seconds depending on your connection speed.

Step Five

View Your Result

The AI returns the predicted waste category along with a confidence score shown as a progress bar. The higher the confidence, the more certain the model is about its classification — use this to guide your recycling decision.

Categories include cardboard, glass, metal, paper, plastic, and general trash. If confidence is low, try a clearer photo.

Tips for Better Results

Good Lighting

Take photos in natural daylight or a well-lit space. Shadows and dim lighting reduce the model's ability to distinguish material types accurately.

Single Item Focus

Centre one waste item per photo. Mixed or cluttered scenes may confuse the classifier — isolating the item gives the best confidence scores.

Sharp & Clear

Avoid blurry or motion-blurred images. Hold your device steady and ensure the item is fully in frame with no important parts cut off.

Retry if Uncertain

A low confidence score means the model is unsure. Try a different angle, better lighting, or crop the image closer to the item and predict again.
