“…There are some constraints such as climatic conditions, soil properties, soil depth, compaction, water availability and drought, waterlogging, aeration, and the nutrient status. Provided that no or just negligible landfill gas emissions are present in the root zone, careful site management including a correct soil placement and handling, soil amelioration, irrigation respectively drainage depending on precipitation, fertilisation, choice of adequate species, can accomplish the necessary environmental conditions (Nixon et al, 2001). Remediation of the sites is just a prerequisite for a successful land use management.…”

“…Short-rotation coppices are often established for afforestation of unused agricultural soils and restoration of landfills (Nixon et al 2001). The most frequently claimed advantage of coppice is an increase in the overall biodiversity of the site, especially in terms of heliophile forest species (Spitzer et al 2008, Van Calster et al 2007, Baeten et al 2009).…”

Coppice forest is an alternative to high forest mainly aimed at the production of firewood with a short rotation period. A new interest in this silvicultural system has arisen with the demand for renewable energy resources. Exploiting the existing root system of the stump, sprouts are advantaged over plants of seed origin, and this advantage could induce changes at the level of a photosynthetic apparatus, especially in young plants. This paper presents a comparison of the photosynthetic ability of young sprouts, young seedlings and mature trees of sessile oak (Quercus petraea (Matt.) Liebl.) growing in a forest stand managed as a coppice-with-standards in the southeast of the Czech Republic. The basic photosynthetic characteristics and transpiration rate at the leaf level were determined using gas-exchange measurement techniques. Data taken in non-limiting conditions were compared with those obtained under limiting soil moisture. The results revealed no differences between the measured parameters of sprouts, seedlings and old trees in non-limiting conditions. Contrastingly, sprouts had the highest photosynthetic capacity and transpiration during drought due to their ability to maintain a higher stomatal conductance as compared with seedlings and old trees. This suggests a better drought tolerance of sprouts compared to seedlings.

“…In particular, the production of biomass destined to produce energy is relatively well documented (e.g. Bolan et al, 2013;Nixon et al, 2001), while the installation of photovoltaic systems (conventional or installed on flexible membranes) is another recently developed opportunity (USEPA, 2013;Mohapatra et al, 2012;Sampson, 2009). The use of closed landfill surfaces to grow energy crops presents excellent potential because this approach is compatible with landscape recovery processes and does not diminish the agricultural surfaces potentially usable for edible crops.…”

The contribution of integrated municipal solid waste (MSW) management systems to greenhouse gas emissions is not negligible, even though it is moderate compared with other anthropogenic activities. The main emission from landfills that accept biodegradable MSW is methane that escapes from the biogas collection system. Such emissions are partially compensated if the collected biogas is exploited for energy production. Further compensation measures would also increase the overall sustainability of the landfill site. This study analyses the possibility of exploiting closed landfills to produce energy based on the case study of the Valdina landfill (Messina, Italy). Two possible scenarios are presented: the installation of a photovoltaic system and the cultivation of giant reed (Arundo donax L.) to be used for energy production through combustion. The results of a preliminary experimental activity are presented for the second scenario. The findings demonstrate the possibility of using the leachate produced in the landfill for irrigation purposes. For each scenario, the costs, potential energy production rate, avoided emissions and issues related to the integration of energy production with the landfill aftercare are evaluated. The presented results suggest that the cultivation of giant reed is the best option, especially during the early post-closure period, in terms of investment (18,000 € against 8,300,000 €), high production yield in the Mediterranean climate, simplicity of cultivation and integration with ordinary post-closure landfill management, limited cost of the energy produced (0.1€ kWh -1 against 0.27€ kWh -1). On the other hand avoided emissions are higher for the photovoltaic plant (27804 t CO 2 against 778 t CO 2 on an horizon of 20 years).
