More than 150 toys were exchanged as parents and children took part in a toy swap.
The campaign, which was run by Petersfield Climate Action Network, was organised to coincide with Plastic Free July.
People were encouraged to drop off any unwanted toys at Winton House and they were then given a token to exchange for a new toy at a later date.
Sarah Moss from Winton House, said: "The toy swap was an absolutely fantastic idea. We are thrilled with the number of people that made donations and came along to collect a toy.
"It's a wonderful way to ensure that these once-loved toys get a second home.
"We hope this is something we can do again in the future."
People were also given the option of donating their token so someone else could use it. Any leftover toys were donated to Homestart Butser.
The campaign was organised in a bid to help reduce waste and demonstrate the importance of buying things second hand.
Shpock's Second Hand Effect report, published in June 2021, shows the annual environmental benefits of the secondhand industry.
It found that through second hand buying and selling Brits saved 90,477 tonnes of CO2 – the equivalent of 7,152 London double decker buses.
The findings also explored the savings that as a nation we have made by buying and selling secondhand items for certain categories.
It turns out cars are the top savers of CO2 at 32,237 tonnes which is the equivalent of around 21,200 midsized cars.
In addition, home and garden products also saved 29,500 tonnes of CO2 which is equivalent to the weight of almost 1.2 million wheelbarrows.
Meanwhile, second hand sports leisure and games items contributed the third biggest saving at 13,671 tonnes which is equivalent to the weight of around 30.1 million footballs.
