Water Absorbing Plantation Clay for Vertical Greenery System

Abstract

Abstract. With the arises of environmental conscious, the usage of vertical garden system has become more popular in urban cities. Citizens can enjoys the benefits of energy and cost saving besides ornamental effect. More investigations have been conducted on green facades led to the cities ecological enhancement.However, limited plants species can be planted for green facades systems as this system does not provide sufficient soil and nutrients for common plants. Alternative plantation methods such as planted box and felt system required additional maintenance attention. The idea of using clay composite which consists of nutritious soil, water absorbing polymer and flexible cement clay potentially become alternative vertical greenery systems that offers economic and sustainable plantation platform for more variety of plants.The fabricating of clay composite involved three processes, they are: mixing, moulding and drying. Physical properties characterisation (density, pH, compression test, aging test and water immersion test) were tested on the dried fabricated clay composite to ensure their sustainability in tropical climate. The results showed that clay composite with 1.5 wt% of cement and 0.3 wt% superabsorbent polymer shows optimum water absorbing properties. This system are expected to enable more agriculture activities in urban living.

“…The internal and external wall surfaces of high‐rise buildings offer great space for vertical green wall gardens, providing many social and environmental benefits for its inhabitants; while enabling the further development of cities and urbanization 6 . Green plants on vertical landscapes can act as natural air filtration and noise abeyance, besides reducing the ambient temperature of the building 7 . However, implementing green wall systems has several obstacles, including the selection of the right plant growing media type.…”

The ideal growing media has to be lightweight (for suspending plants vertically), be of granular materials (for root growth), and capable of supplying and retaining essential nutrients for the plants.…”

“…The systems that allow greening a building vertical surface are classified with different terms in literature: vertical greening systems (Perini et al, 2011;Oluwafeyikemi and Julie, 2015), vertical greenery systems (Wong et al, 2010;Azkorra et al, 2014;Pérez et al, 2017;Coma et al, 2017), green walls (Kontoleon and Eumorfopoulou, 2010;Su and Lin, 2015;Wong and Baldwin, 2016;Djedjig et al, 2017;Vox et al, 2018b), vertical greens (Perini et al, 2011), vertical gardens (Peck et al, 1999;Alexandri and Jones, 2008;Perini and Ottelé, 2014), bio shaders (Ip et al, 2010), vertical landscaping (Allan and Kim, 2016;Yu et al, 2016), green façades (Coma et al, 2014;Flores Larsen et al, 2015;Hoelscher et al, 2016;Blanco et al, 2018), living walls (Charoenkit and Yiemwattana, 2016;Safikhani and Baharvand, 2017). Such a wide classification often leads to a non-real interpretation of the results obtained considering the different greening systems.…”
