[An excerpt from the wiki site]
Social enterprises play an important role in society. Their distinguishing feature is that they trade to support their social objectives rather than for personal gain. In so doing, they provide much-needed goods and services, often where the private sector has chosen not to. Social enterprises provide health and care services, recycling services, new and recycled goods, transport, community facilities, renewable energy, construction services, housing and access to broadband telecommunications. This is often combined with providing on-the-job training in a supportive environment for disadvantaged people, including people who have a disability or are long-term unemployed.
