Due to current construction trends, we are constantly searching for eco-friendly materials that have a low carbon footprint. This is the case of the analyzed material, and additional thermographic heat distribution inside the material during a fire resistance test proves that it is also a perfect insulation material, which could be applied in addition of popular isolating materials. This paper presents the results of certain hemp–lime composite studies and the potential for using hemp–lime composite for the structural construction industry. Hemp–lime composite heat transfer coefficient, fire resistance, and bulk density properties are compared to those of other commonly used construction materials. The obtained results show that the material together with supporting beams made of other biodegradable materials can be the perfect alternative for other commonly used construction materials. Keywords: hemp–lime composite; thermal conductivity; low-energy buildings; specific energy absorption; natural fiber 1. Introduction The idea of sustainable development in construction, i.e., one that limits the negative impact of buildings on the environment and is user-friendly, is gaining in popularity [1]. Building in an eco-friendly way is becoming common not only among office space developers, who apply for global Leadership in Energy and Environmental Design (LEED) or Building Research Establishment Environmental Assessment Method (BREEAM) certificates, but also among individuals thinking about building a year-round or recreational house [2]. Hemp lime is a material that has a chance to revolutionize the world’s natural construction as it strongly fits into the trend of renewable resources. It has a negative carbon footprint because during its growth, hemp absorbs more carbon dioxide than is used later to make building materials [3,4]. Hemp lime has high thermal insulation, heat accumulation, vapour permeability, is non-flammable, can be used as a fertiliser after demolition and is 100% decomposable [5,6]. The objective of the work is the experimental identification of heat conductivity for three experimental mixtures of hemp–lime composite used for construction purposes analyzed for the use for construction of single-family buildings. Industrial hemp (Cannabis sativa L.) has a long history with human civilization and was often found near early nomadic settlements close to streams in Materials 2020, 13, 1011; doi:10.3390/ma13041011 www.mdpi.com/journal/materials Materials 2020, 13, x FOR PEER REVIEW 2 of 15 multitude of uses covering a range of products derived from fiber or oilseed that have been known throughout history [8]. True hemp (industrial hemp) found common application during the 19th century. The sturdy fibers of the plant—well-known and valued for their strength—were used to make ropes for maritime shipping and other industry, as well as paper and textiles [9]. Hemp use has been suppressed in recent times, but due to its usefulness and the ecological advantages in harvesting hemp over cotton and trees, there has been a call for hemp use which is growing worldwide [10]. The hemp–lime composite (Figure 1) consists of water, hemp shiv, lime, and other additives to further improve its properties [5]. Mixing and compressing the components results in a light and appropriately strong material whose structure makes it possible to fill any space or—when applying special formwork—build a complete partition [11,12]. Hemp–lime composite may also be used to make floor tiles or roof and ceiling insulation. Hemp–lime composite shows very poor load-bearing strength and for that reason, it may only be used with specifically designed load-bearing structures or pillars, most typically made of softwood timber [13].

Hemp lime composite owes its excellent thermal conductivity properties to high hemp shiv porosity [16]. Its properties attract even more people both in this country and abroad to launch investigations and promote hemp–lime composite applications in the construction of new or improving thermal insulation performance of the existing buildings [17–20]. Such composite materials can appear to have variations to their properties due to the existence of structural changes [21]. The properties of the composite are influenced by many factors such as the morphology of the filers, the orientation of the filers, porosity, degree of compaction, the distribution of the filers, and others like gluing [22,23]. Also, some new information regarding nanotubes and fibers in concrete and cementitious materials are worth mentioning [24,25].

    Minerals In Your Home Activity Book Minerals in Your Home Activity Book Written by Ann-Thérèse Brace, Sheila Stenzel, and Andreea Suceveanu Illustrated by Heather Brown Minerals in Your Home is produced by MineralsEd. © 2017 MineralsEd (Mineral Resources Education Program of BC) 900-808 West Hastings St., Vancouver, BC V6C 2X4 Canada Tel. (604) 682-5477 | Fax (604) 681-5305 | Website: www.MineralsEd.ca Introduction As you look around your home, it is important to think of the many things that you have and what are they made from. It’s simple - everything is made from Earth’s natural resources: rocks, soil, plants, animals, and water. They can be used in their natural state, or processed, refined and manufactured by people into other useable things. The resources that grow and can be replaced when they die or are harvested, like plants and animals, are called renewable resources. Those that cannot be regrown and replaced, like rocks, soil and water, are called non-renewable resources. All natural resources are valuable and we must use them conservatively. Mineral resources are natural Earth materials that must be mined from the ground. We use them every day, and they are non- renewable. Some are changed very little before they are used, like the rock granite for example, that is commonly used to make kitchen countertops or tombstones. Other mineral resources, like those that contain useful metals, must be processed to extract the metal ingredient. The metal is then manufactured into different parts of a product, like a toaster or a smartphone. Whether you are practicing violin in your room, eating a meal in the kitchen, watching TV in the living room or brushing your teeth in the bathroom, your daily activities use things that come from mineral resources.

Thermogravimetric analysis (TGA), limited oxygen index (LOI), and the Underwriters Laboratories (UL)-94 horizontal and vertical tests were carried out for evaluating the effectiveness of these FR treatments. Flat-coupon tensile test was performed to evaluate the effects of FR treatment on the mechanical properties of the FFRP composites. For both fire retardants, the results showed that the temperature of the thermal decomposition and the LOI values of the composites increased as the FR content increases. Under the UL-94 vertical test, the FFRP composites with 20% and 30% APP (i.e., by mass content of epoxy polymer matrix) were self-extinguished within 30 and 10 s following the removal of the flame without any burning drops, respectively.

  • Sustainability by Design in Textile Products and Fashion
    New Design Ideas Vol.1, No.1, 2017, pp.37-49 SUSTAINABILITY BY DESIGN IN TEXTILE PRODUCTS AND FASHION Nesrin Önlü1* 1Textile & Fashion Design Department, Fine Arts Faculty, Dokuz Eylul University, Izmir, Turkey Abstract. Sustainability is to deliver everything we need to live, without disturbing the natural equilibrium, to future generations and to produce and sustain them in ways that they can benefit. Sensitivity to the environment is essential in sustainability. Manifesto, take it from nature, give it back to nature, or reapply it. Natural return is the goal of sustainability to produce environmentally friendly products and to recreate less consuming society. We have to spend our consumption habits for a sustainable life, we must adopt slow fashion instead of fast fashion in order to reduce the most damage to the environment in the concept of fashion which is effective in every area of our life today. Fashion, on the other hand, is a concept that is connected to a much more design than any other period, and has become a phenomenon that shapes every stage of our life, every field. The ultimate in design is the design and production of much more product variety than we can consume. This kind of production damages the neighborhood too much and confronts future generations with a world that can not be experienced. For this reason, this article will talk about the importance of sustainability, its contribution to sustainability of design, and how sustainability can be achieved through design within textiles and fashion. Keywords: sustainability, design, textile, fashion.

  • RAMMED EARTH: Synergy of Natural Material in Artificial Earthscapes
    RAMMED EARTH: Synergy of Natural Material in Artificial Earthscapes The thesis explores the use of soil, a traditional and sustainable building material, situated in the landscape of an abandoned surface quarry mine, defined as drosscape by Lars Lerup and Alan Berger. In taking advantage of this new artificial landscape as a material for new production, the site develops into a vocational learning center and temporary housing, which serve to spread awareness of Rammed Earth construction as a refined, modern alternative to contemporary materials, that has matured beyond its origins as primitive mud huts set in warm, dry climates. The main facility provides a testing ground for application and research of Rammed Earth construction, expanded upon by a continual construction of various housing units throughout the lifespan of the project, utilized as a practical learning experience for the trainees. This thesis project proposes to use an open pit mine’s own materials to inhabit it with new structures, transforming the ground into a space that brings awareness of the artificial construction from natural materials. The abandoned open- pit mine therefore provides both an opportunity and a critique, as suggested by Solà-Morales, to present a solution to the contextual destructive practices.

Abstract: Outdoor tourism is a form of outdoor holiday that is growing rapidly today, and that stands out from other forms of tourism for its immediate relationship with the landscape which becomes for the tourist the main attraction of the holiday intended as a break from ordinary urban life. Outdoor tourism today represents a growing percentage in the tourism sector, in which mobile homes are the real players. Despite the considerable use of this product in open-air accommodations located in relevant landscapes, there is still no sensitivity in the constructive approach and in the choice of materials in terms of sustainability. In the open-air tourism sector, the lack of ecological sensitivity results from two levels of application: one regarding the whole settlement and the public spaces of outdoor accommodations and one regarding the mobile unit from the design to the production process. This paper will provide some practical strategies to introduce the ecological theme in the mobile home for the tourism sector. The research aims to analyze the production system of mobile Citation: Berizzi, C.; Nirta, S.; homes in order to introduce alternative materials within the existing assembly line.
