Ei amcan cyffredinol yw cydnabod yr effaith negyddol ar gymunedau sy'n byw ger safle tirlenwi a'i nod yw gwrthbwyso rhai o'r effeithiau hynny drwy'r dulliau a nodir yn y cynllun. Er mwyn cyflawni hyn, dyrennir cyfran o'r refeniw a godir o'r dreth gwarediadau tirlenwi i'r cynllun, i'w ddyfarnu fel grantiau i brosiectau llwyddiannus. Dros y pedair blynedd diwethaf, mae grantiau o £5,000 i £50,000 wedi bod ar gael mewn dau gylch ymgeisio blynyddol, gydag un prosiect sylweddol y flwyddyn yn cael cynnig cyllid o hyd at £250,000.
Its overall objective is to recognise the negative impact for communities living near a landfill site and aims to offset some of those impacts through the means set out in the scheme. To achieve this a proportion of the revenues raised from landfill disposals tax is allocated to the scheme, to be awarded as grants to successful projects. Over the last four years, grants of £5,000 to £50,000 have been made available in two annual bidding rounds, with one significant project per year being offered funding of up to £250,000.
