What unskilled work doesn't involve too much social contact?

Conservation related work is an option. qualifications are sometimes required but there will be posts that don't need prior qualifications, and where you can advance doing self-study courses.

Also some conservation work is voluntary, but these sometimes provide food and accommodation if they involve away periods, and doing it voluntarily can lead to paid work.

Conservation includes: footpath maintenance (rights of way, routes in country parks), groundwork of all kinds on national trust sites, country parks, local nature reserves, linear parks, british council for conservation volunteers, wildlife trust, etc etc. Sometimes this is working in a group, but not mentally engaging with the others, just doing a component of the work, but many are attracted by the solitary nature of such jobs.

Grounds staff are needed in many urban areas for upkeep of parks, cemeteries, hospital grounds, private grounds/company offices in parkland, maintenance of shrubberies and local playing fields on housing estates. The work involves routine tasks such as hoeing, raking, trimming, pruning, grass cutting, litter picking.

Away from open spaces cleaning is often viewed rather disdainfully, and isn't just antisocial hours (usually night) or minimum wage, or just domestic (house cleaning). It is a flourishing industry, and can involve permanent and quite well-paid posts and contract work - cleaning hospitals, factories, offices, public ammenities (not just loos - theatres, cinemas, community centres), schools, colleges, universities, shopping malls, retail premises..........  You can get qualifications by day release and distance learning, and you can get a degree in it. The work may be team based but not necessarily social and a lot of such work is solitary.

Wastes management is hugely important - not just binmen - there is a great deal of specialised waste management including the ruinning of landfil sites, organising the logistics of waste movements, specialised wastes - chemical, medical, hazardous, building wastes, packaging, also wastes conversion, and then there is a vast industry on recycling, where the AS mind can be put to good work and often working alone. Again there is training and qualifications up to degree level and postgraduate qualifications.
