Ruling on items confiscated from students who break the rules

What is the ruling on items confiscated from students for breaking the rules, such as (pumpkin or sunflower etc) seeds, chewing gum, masbahahs, rings and so on? 
I confiscate (pumpkin or sunflower etc) seeds and chewing gum and throw them in the trash. As for masbahahs and rings, I hand them over to the administration, but the administration says: Give them back so that we will owe them nothing.
To sum up, the question is: what is the ruling on items confiscated from students in such cases?.

Praise be to Allaah.

If these students have been informed about the things which they are not allowed to use in class or bring to school and have been told that whoever breaks the rule will have it confiscated from him, it is permissible to punish those who break the rules by confiscating them. If they are items of little value, such as pumpkin seeds, it is permissible to dispose of them, but if they are valuable items they should be returned to the student or his guardian at the end of the day or at the end of the school year, according to whatever the school thinks is best. 

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) was asked: Is it permissible for the teacher to take things from some students which may be valuable, with which they were playing in class during the lesson, and give them to the school? 

He replied: That is based on the issue of whether it is permissible to punish by taking wealth or property. Some of the scholars say that it is not permissible to punish by taking wealth or property in any case except what is mentioned in the texts. Some of them say that punishing by taking wealth or property is permissible and this is the more correct view. But if the students have something that they are playing with and he has warned them, for example by writing on the blackboard or posting a notice, that if anyone brings something and plays with it, it will be confiscated, then in that case he may confiscate it, but if it is something valuable and the student is poor - for example -- then it should be kept safely at the school, and at the end of the year it should be given to the student or his guardian.

And Allah knows best.

Learn Holy Quran because it will be a proof for us muslim on the Day of Judgment.
This is due to the statement of the Messenger: “And the Quran is a proof for you or against you.” [Muslim] so the deputy of every Muslim is to read quran and learn quran with tajweed so one of two things will occur with this proof, the Book of Allah. And this quran education will be in your favor, a proof for us on the Day when we will need every single good deed and learning quran along with doing quran memorization is one of it and to add more spread the quran teaching and spread the kids quran knowledge and listening to quran online and understand the quran tafseer , it will be something standing against us and follow the guidance of or prophet Muhammad peace be upon him, and these good deeds will be a proof against us! Who could be saved from the terrors of that Day if Allah’s own Speech is against him?!?! Think carefully, so reading Arabic Quran and teaching our kids quran qaida with the tafseer of quran  and let the kids memorize quran dear Muslim brother or sister, about your position with the reading Quran! Are you neglecting it, contradicting it, being heedless of its orders and prohibitions, are you thinking deeply over it?! Will it be on your side on the Day of Judgment.? So learn quran recitation! O Allah! We ask you, by Your Glorious Speech and the rest of your beautiful Names and Attributes, to make the Quran a proof for us! So the Quran tutor should let his student know about these facts also,
